Authors: Traore Bintou Yasmine , Zongo Bilassé
Published: May 2023

L’activité de pépinière est en plein essor dans les villes du Burkina Faso. Toutefois, cette activité demeure peu connue des habitants. L’objectif de notre étude était d’évaluer l’impact des secteurs phytogéographiques sur la diversité des espèces produites et la valeur socio-économique des pépinières du Burkina Faso. Pour une meilleure connaissance de ces pépinières, 166 pépinières ont été identifiées et étudiées à travers un inventaire floristique et une enquête semi-structurée. Trois cent vingt (320) espèces réparties en 84 familles et 226 genres ont été recensées. Au sud soudanien, les familles les plus représentées en termes d’espèces sont les Fabaceae, Euphorbiaceae et Arecaceae. Au nord soudanien prédominent les Fabaceae, Euphorbiaceae et Arecaceae. Au sahel prédominent les Fabaceae, Euphorbiaceae et Malvacea. Les plantes sont majoritairement à usage ornemental ou destinées à la plantation pour la production de fruits et/ou le reboisement. Les pépinières individuelles prédominent dans nos zones d’étude et seraient les plus rentables. Les pépinières constituent une activité économique rentable et source d’emploi pour de nombreuses personnes. Dans les zones soudaniennes prédominent les espèces exotiques par rapport aux espèces locales. Ces résultats montrent l’importance de la valorisation des espèces locales.

English title: Floristic diversity and socio-economic values of nurseries following a phytogeography transect in Burkina Faso (West Africa)

The nursery activity is booming in the cities of Burkina Faso. However, this activity remains little known to the inhabitants. The objective of our study was to assess the impact of phytogeography sectors on the diversity of species produced and the socio-economic value of nurseries in Burkina Faso. In order to contribute to a better knowledge of these nurseries, 166 nurseries were identified and studied through a floristic inventory and a semistructured survey. Three hundred and twenty (320) species in 84 families and 226 genera have been recorded. In South Sudanese, the most represented families in terms of species are Fabaceae, Euphorbiaceae and Arecaceae. in North Sudan the Fabaceae, Euphorbiaceae and Arecaceae predominate. In Sahelian nurseries predominate the Fabaceae, Euphorbiaceae and Malvacea. The plants are mainly for ornamental use or intended for planting for fruit production and/or reforestation. Individual nurseries predominate in our study areas and would be the most profitable. Nurseries are a profitable economic activity and a source of employment for many people. In Sudanian areas, exotic species predominate over local species. These results show the importance of valuing local species.

A spatio-temporal cartography and landscape metrics of urbanization patterns in Algerian low-Sahara. The case of Ouargla City
Authors: Dechaicha A. , Alkama Dj.
Published: May 2023

Monitoring and assessment of spatial and landscape transformations generated by uncontrolled urbanization is currently a key step in any oasis sustainability project. Through a landscape-metrics based approach using a multi-time series of Landsat images (1985-2000-2015), we have tried to assess the spatial growth of Ouargla City (Algeria) over the last three decades, by highlighting its impact on the oasis ecosystem. The results of the spatio-temporal cartography have shown a significant spatial growth of built-up areas, against an excessive decline and progressive fragmentation of the palm grove, which have negatively influenced the oasis ecosystem functioning. The main aim of this paper is to show the utility of satellite images and landscape metrics for monitoring uncontrolled urbanization and assessing its impacts on oasis landscapes.

Groundwater is often the preferred source for human consumption, irrigation and industry. In Algeria, many people count on well water for their drinking water supply and irrigation of agricultural lands; especially in rural areas, which is a strategic reserve of which quality must be assured. Groundwater protection requires the detection of origins of pollution and its consequences on the ecological system. The region of Bouirahas seen water-borne diseases occurrence caused by groundwater pollution, which has led us to look for the origin of this problem. It is considered like a high-risk area because it has recorded a large number of Toxi-food collective, Viral Hepatitis A, typhoid fever and Choléra cases in 2018. The study carried out based on the potential risks to human health and the GIS for a period of eight years (from 2008 to 2015), has allowed us to the elaboration of water-borne disease mapping of the whole region and to find that the most affected municipalitie sare: Bouira, Sour El Ghozlene, Lakhdaria and Ain Bessem .The correlation between these diseases and the irrigated perimeters by wadis is very strong in this municipalities.

Authors: Thorogood Nancy P. , Waheed Zeina , Chernesky John , Burkhart Ian , Smith Judith , Sweeney Shannon , Wudlick Rob , Douglas Sam , Wang Di , Noonan Vanessa K.
Published: May 2023

Background

Spinal cord stimulation (SCS) clinical trials are evaluating its efficacy and safety for motor, sensory, and autonomic recovery following spinal cord injury (SCI). The perspectives of people living with SCI are not well known and can inform the planning, delivery, and translation of SCS.

Objectives

To obtain input from people living with SCI on the top priorities for recovery, expected meaningful benefits, risk tolerance, clinical trial design, and overall interest in SCS.

Methods

Data were collected anonymously from an online survey between February and May 2020.

Results

A total of 223 respondents living with SCI completed the survey. The majority of respondents identified their gender as male (64%), were 10+ years post SCI (63%), and had a mean age of 50.8 years. Most individuals had a traumatic SCI (81%), and 45% classified themselves as having tetraplegia. Priorities for improved outcome for those with complete or incomplete tetraplegia included fine motor skills and upper body function, whereas priorities for complete or incomplete paraplegia included standing and walking, and bowel function. The meaningful benefits that are important to achieve are bowel and bladder care, less reliance on caregivers, and maintaining physical health. Perceived potential risks include further loss of function, neuropathic pain, and complications. Barriers to participation in clinical trials include inability to relocate, out-of-pocket expenses, and awareness of therapy. Respondents were more interested in transcutaneous SCS than epidural SCS (80% and 61%, respectively).

Conclusion

SCS clinical trial design, participant recruitment, and translation of the technology can be improved by better reflecting the priorities and preferences of those living with SCI identified from this study.
Buckling Analysis of Cold-Form Steel Built-Up Column with Two Sections
Authors: Sherin Fathima , U Minu
Published: May 2023

Cold-formed steel has a high strength ratio, high corrosion resistance, and ease of fabrication. So, their range of applications has rapidly expanded as a primary structure for flexural and compression members due to their varieties of advantages. The increased load-carrying capacity and span length can be achieved by the build-up of the section connecting two or more individual sections by self-drilling screws or spot welds. This project deals with the buckling analysis of cold-form built-up sections using ANSYS software. The sections were made by connecting two sections using self-drilling screws. The sections used for the study were channel sections without lips. This project mainly aims to study the effect of buckling loads by changing the screw spacing. According to the findings, buckling load increases as screw spacing decreased. In contrast to open sections, closed sections display variable findings.

1H NMR Spectroscopy is widely used technique, but until recently was of limited practical importance in pharmaceutical and chemical education. Teaching1H NMR spectroscopy remains a challenge in all the chemistry labs, as the number of facts obtained from each experiment is easily overwhelming for the students. We developed four different experimental settings for the undergraduates which connect interdisciplinary problem-solving approaches with the hands-on experience in NMR. The set of the experiments consists of amino acids identification, logP value determination, quantitative determination of the marketed over the counter drugs, and pKa value determination. We could show that our approach to teach NMR has significantly improved the understanding of the technique among our students.

Exploring the Contribution of the Service Sector to Economic Growth and Job Creation: Empirical Evidence from South Asia
Authors: Sadiq Rozina , Sheraz Sahar , Ali Mahnaz Muhammad , Nazeer Shabnam
Published: May 2023

The service industry is the main driving force behind the global economy, responsible for creating the most employment opportunities and stimulating the most economic growth in both developed and developing countries. However, there is concern among policymakers regarding whether an increasing emphasis on the service industry will actually lead to job creation or not. Therefore, the purpose of this study is to investigate the impact of service sector growth on economic expansion and job creation in six developing nations of South Asia: Bangladesh, Pakistan, Iran, India, Nepal, and Sri Lanka. The study collected data over a period of 30 years, from 1990 to 2020, and utilized two models, with the generalized method of moments (GMM) being employed to estimate the findings. The results demonstrate a significant and favorable relationship between the expansion of the service industry and economic growth, as well as employment levels. To enhance the growth rate of developing economies and increase exports of service-related products, it is recommended to foster a favorable environment in the service sector. This can include creating conditions that are supportive of business, enabling greater ease of operation, and providing a stable political climate.
An exploratory assessment of the Bering-Chukchi-Beaufort Seas stock of bowhead whales using a stochastic population dynamics model
Authors: Poole David , Givens Geof H.
Published: May 2023

The stochastic population dynamics model used by Aboriginal Whaling Management Procedure developers is revised to correct weaknesses related to uncertainty parameterisation and replacement yield estimation. Two variants of this model, along with the standard deterministic version, are used to assess the Bering-Chukchi-Beaufort Seas stock of bowhead whales. The variants differ with respect to the magnitude and complexity of the stochastic variation they introduce into natural mortality and birth/calf survival processes. An allowable catch statistic, E (Q0), is defined for appropriate use with stochastic model assessments. Using the same assessment methods, likelihood and priors as IWC (1999a), 5th percentiles of E (Q0) were found to be 117, 106 and 91 for the deterministic, simpler stochastic and extreme stochastic models, respectively. Bayes factor results show that there is no evidence suggesting that either stochastic model should be favoured over any simpler alternative, and the deterministic model yielded the best fit overall. The E (Q0) estimates confirm and strengthen past IWC Scientific Committee inference that under current bowhead subsistence hunting levels the stock should continue to increase towards stabilisation above its maximum sustainable yield level.
Biology and conservation of the franciscana (Pontoporia blainvillei) in the north of Rio de Janeiro State, Brazil
Authors: Di Beneditto Ana Paula Madeira , Ramos Renata Maria Arruda
Published: May 2023

This paper describes the interactions of the franciscana (Pontoporia blainvillei) with fisheries in the north of Rio de Janeiro State (210 18’S-220 25’S) and presents new information on its biology. A total of 181 dolphins were caught in gillnet fisheries in northern Rio de Janeiro from 1986-1999. The annual catch per unit effort (CPUE) values varied from 0.2-1.8 dolphins per gillnet fishing effort. Incidental captures were recorded throughout the year, usually less than 10 n.miles from shore, in depths less than 30m and in surface-set gillnets. There was no difference in the proportion of sexes (1 male:1.1 females). Males ranged from 66-130.0cm and 0-5 years and females from 74-147.5cm and 0-9 years. The predicted asymptotic length (using the Gompertz model) was 121.9cm for males and 145.6cm for females. Calving occurs throughout the year, with no seasonal pattern. Females attain sexual maturity at 3 years and 130.0cm in length and males at 2 years and 115.0cm. Individuals up to the age of three years represented 74% of the dolphins captured. Franciscana preferentially feed on the teleosts Stellifer sp., Anchoa filifera, Pellona harroweri and Isopisthus parvipinnis, measuring up to 10cm of length, and on the cephalopods Loligo sanpaulensis and L. plei. No internal parasites were observed. The barnacle Xenobalanus globicipitis was recorded on only one individual. Sightings were recorded in all seasons and 90% of them were obtained up to 5 n.miles from shore, in waters up to 15m deep. Around 70% of groups sighted consisted of up to five dolphins. Estimates of the population size and continuous gillnet fleet monitoring are required to conserve franciscana in the northern limit of its distribution range. The differences in the somatic, reproductive and genetic patterns of franciscana represent important aspects that may be used as evidence to best define their stocks. These variations may reflect the reduction of gene flow between populations, the allocation of resources between growth and reproduction and/or the influence of environmental features, such as water temperature and food availability.

Published: May 2023

System evaluation is carried out with the aim of knowing system weaknesses that hinder users from implementing them. Inventory application users in Badung Regency, based on interviews conducted, had never been evaluated and there were several records collected regarding complaints from users. This study aims to evaluate the value of the success and speed of doing tasks with Performance Measurement, RTA and SUS Techniques. Based on the results of processing the data obtained with the performance measurement technique, it shows that pages are generally quite effective because they function properly, even though there was an error in one of the tests in carrying out the task by the respondent. This is due to a period mismatch caused by the user's own error, namely forgetting to change the period. Efficiency when viewed from the results of the data obtained with performance measurement techniques, it is generally known that inventory applications are quite efficient. For user satisfaction, the score for the respondent's questionnaire is 61.18 which is obtained, this means that the score is smaller than the SUS standard score, which is 68. So it can be said that respondents are not satisfied using the Inventory Application. The results obtained from the usability testing process show that the Inventory Application page which is the object of research still does not meet the criteria for a product with good usability. This can be seen in the assessment of the level of effectiveness, efficiency, and user satisfaction. This inventory application is not able to meet the good criteria for these three aspects.

Negotiating epistemic congruence
Authors: Granqvist Angelica
Published: May 2023

Based on fieldwork in an upper-secondary school in Sweden, this paper centers on Swedish as two school-subjects: Swedish (SWE) and Swedish as a second language (SSL), as taught in one class. Adhering to separate curricula, and taught by SWE and SSL teachers respectively, they are often implemented as physically separated subjects. By contrast, this paper explores three different learning spaces in relation to everyday negotiations of belonging and participation among the migrant language learners: combined whole-class teaching, a separate SSL group, and combined book-group discussions. Drawing from the notion of the classroom as a contact zone (Canagarajah, 2020) and theory of spatial repertoire (Pennycook & Otsuji, 2014), I discuss how minoritized second language learners negotiated social belonging and linguistic participation in these differently embodied learning spaces. Engaging a linguistic ethnographic approach, the data production consisted of fieldnotes from classroom observations, audio-recorded book discussions and semi-structured interviews. The material was analyzed by means of an epistemic stance analysis. Findings indicate that while an epistemic incongruence prevailed in the combined whole-class teaching, the reverse was found in the separate SSL group. In the space between these opposites, the book-group discussions served as a growing ground for epistemic congruence at the interface of SWE and SSL. The article thus contributes insights into how the organization of SWE and SSL affects how students navigate their multiple and hybrid identities as well as the extent to which they feel a sense of social belonging in order to fully participate in different educational practices.

Challenges and solutions in determining dilution ratios and emission factors from chase measurements of passenger vehicles
Authors: Leinonen Ville , Olin Miska , Martikainen Sampsa , Karjalainen Panu , Mikkonen Santtu
Published: May 2023

Abstract. Vehicle chase measurements used for studying real-world emissions apply various methods for calculating emission factors. Currently available methods are typically based on the dilution of emitted carbon dioxide (CO2) and the assumption that other emitted pollutants dilute similarly. A problem with the current methods arises when the studied vehicle is not producing CO2, e.g., during engine motoring events, such as on downhills. This problem is also encountered when studying non-exhaust emissions, e.g., from electric vehicles. In this study, we compare multiple methods previously applied for determining the dilution ratios. Additionally, we present a method applying Multivariate Adaptive Regression Splines and a new method called Near-Wake Dilution. We show that emission factors calculated with both methods are in line with the current methods with vehicles producing CO2. In downhill sections, the new methods were more robust to low CO2 concentrations than some of the current methods. The methods introduced in this study can hence be applied in chase measurements with changing driving conditions and be possibly extended to estimate non-exhaust emissions in the future.
Glacial-interglacial sea water isotope change near the Chilean Margin as reflected by δ2H of C37 alkenones
Authors: Hättig Katrin , Varma Devika , Schouten Stefan , van der Meer Marcel T. J.
Published: May 2023

Abstract. Hydrogen isotopic compositions of C37 long chain alkenones (δ2HC37) have been proposed as a proxy for past seawater salinity and applied in several regions. However, previous studies were based solely on a single core and often suggested unlikely large changes in salinity. Here we present a new δ2HC37 record, in combination with oxygen isotopes of benthic foraminifera from the same samples, from a sediment core from the Chilean Margin (ODP site 1235). The observed negative shift in δ2HC37 of 20 ‰ during deglaciation was identical to that of the nearby located, but deeper, ODP core 1234, suggesting a regionally consistent shift in δ2HC37. This shift translates into a hydrogen isotope shift of the surface seawater (∆δ2HSW) of ca. 14 ‰, similar to glacial-interglacial reconstructions based on other δ2HC37 records. The reconstructed bottom seawater oxygen isotope change based on benthic foraminifera during the last deglaciation is approximately 0.8 ‰, in line with previous studies. When translated into ∆δ2HSW using the modern open-ocean waterline this would suggest a shift of ca. 5 ‰, smaller than the reconstructed surface seawater shift based on alkenones. The higher change in surface δ2HSW suggests that the surface water experienced more freshening during the Holocene than bottom waters either due to increased freshwater input or reduced evaporation, or a combination of the two.
Unique ocean circulation pathways reshape the Indian Ocean oxygen minimum zone with warming

Abstract. The global ocean is losing oxygen with warming. Observations and Earth system model projections suggest, however, that this global ocean deoxygenation does not equate to a simple and systematic expansion of tropical oxygen minimum zones (OMZs). Previous studies have focused on the Pacific Ocean; they showed that the outer OMZ deoxygenates and expands as oxygen supply by advective transport weakens, the OMZ core oxygenates and contracts due to a shift in the composition of the source waters supplied by slow mixing, and in between these two regimes, oxygen is redistributed with little effect on OMZ volume. Here, we examine the OMZ response to warming in the Indian Ocean using an ensemble of Earth system model high-emissions scenario experiments from the Coupled Model Intercomparison Project phase 6. We find a similar expansion-redistribution-contraction response, but show that the unique ocean circulation pathways of the Indian Ocean leads to far more prominent OMZ contraction and redistribution regimes than in the Pacific Ocean. As a result, only the outermost OMZ layers (oxygen > 180 μmol/kg) expand. The Indian Ocean experiences a broad oxygenation in the southwest driven by a reduction in waters supplied by the Indonesian Throughflow in favor of high-oxygen waters supplied from the South Indian Gyre. Models also project a strong localized deoxygenation in the northern Arabian Sea due to the rapid warming and shoaling of marginal sea outflows (Red Sea and Persian Gulf). We extend the existing conceptual framework used to explain the Pacific OMZ response to interpret the response in the Indian Ocean.

Abstract. Evaporation (ET) is one of the crucial components of the water cycle, which serves as the nexus between global water, energy, and carbon cycles. Accurate quantification of ET is, therefore, pivotal in understanding various earth system processes and subsequent societal applications. The prevailing approaches for ET retrievals are either limited in spatiotemporal coverage or largely influenced by choice of input data or simplified model physics, or a combination thereof. Here, using an independent mass conservation approach, we develop water balance-based ET datasets (ET-WB) for the global land and the selected 168 major river basins. We generate 4669 probabilistic unique combinations of the ET-WB leveraging multi-source datasets (23 precipitation, 29 runoff, and 7 storage change datasets) from satellite products, in-situ measurements, reanalysis, and hydrological simulations. We compare our results with the four auxiliary global ET datasets and previous regional studies, followed by a rigorous discussion of the uncertainties, their possible sources, and potential ways to constrain them. The seasonal cycle of global ET-WB possesses a unimodal distribution with the highest (median value: 65.61 mm/month) and lowest (median value: 36.11 mm/month) values in July and January, respectively, with the spread range of roughly ±10 mm/month from different subsets of the ensemble. Auxiliary ET products illustrate similar intra-annual characteristics with some over/under-estimation, which are completely within the range of the ET-WB ensemble. We found a gradual increase in global ET-WB from 2003 to 2010 and a subsequent decrease during 2010–2015, followed by a sharper reduction in the remaining years primarily attributed to the varying precipitation. Multiple statistical metrics show reasonably good accuracy of monthly ET-WB (e.g., a relative bias of ±20 %) in most river basins, which ameliorates at annual scales. The long-term mean annual ET-WB varies within 500–600 mm/yr and is consistent with the for auxiliary ET products (543–569 mm/yr). Observed trend estimates, though regionally divergent, are evidence of the increasing ET in a warming climate. The current dataset will likely be useful for several scientific assessments centering around water resources management to benefit society at large. The dataset is publicly available at https://doi.org/10.5281/zenodo.7314920 (Xiong et al., 2023).
REAL-TIME LIDAR-INERTIAL POSITIONING AND MAPPING FOR FORESTRY AUTOMATION

Abstract. Accurate real-time positioning in forests is challenging due to GNSS signal degradation and an unstructured spatial environment that is difficult to conceptualize through visual sensing. Positioning is vital in any forestry automation application, such as collecting inventory, harvesting, or search and rescue missions. Lidar and inertial based solutions are popular, however they often obtain real-time computation by effectively compressing the number of measurement points to track utilizing regular geometric shapes that do not adapt well to forest. Other solutions sacrifice the high-frequency of positioning estimates or they rely on post-processing. We propose a real-time lidar-inertial SLAM-based approach that utilizes NDT scan registration, factor graphs and loop closure corrections to produce accurate and high-frequency pose estimates. To test our method, data was captured with a lidar and imu sensor mounted on a stick surveying forest sites. Ground truth trajectory for accuracy evaluation was computed by fine registering individual laser scans onto a high-quality reference point cloud recorded from the same forest area using terrestial and airborn laser scanning methods. Experiments shows, that our method can produce real-time position estimates up to 200 Hz within 2–15 cm error.

Abstract. This work represents a large step into modern ways of fast 3D reconstruction based on RGB camera images. Utilizing a Microsoft HoloLens 2 as a multisensor platform that includes an RGB camera and an inertial measurement unit for SLAM-based camera-pose determination, we train a Neural Radiance Field (NeRF) as a neural scene representation in real-time with the acquired data from the HoloLens. The HoloLens is connected via Wifi to a high-performance PC that is responsible for the training and 3D reconstruction. After the data stream ends, the training is stopped and the 3D reconstruction is initiated, which extracts a point cloud of the scene. With our specialized inference algorithm, five million scene points can be extracted within 1 second. In addition, the point cloud also includes radiometry per point. Our method of 3D reconstruction outperforms grid point sampling with NeRFs by multiple orders of magnitude and can be regarded as a complete real-time 3D reconstruction method in a mobile mapping setup.

Abstract. In recent years, wearable devices such as smart bands and smartwatches have gained widespread popularity due to their ability to provide various health and fitness applications by detecting and analyzing the human body and motion information. However, the accuracy of location-based services can be limited, especially in urban areas and indoors. This study proposes a series of smartwatch Pedestrian Dead Reckoning (PDR) improvements based on 9 Degrees of Freedom (DOF) IMU orientation estimation, which includes the heading estimation of human movement and a novel pre-trained velocity regression model. The proposed system holds the potential to enhance positioning accuracy and augment navigation availability for smartwatch users, thus offering potential applications across various fields. This study makes significant contributions to the field of smartwatch navigation by proposing a GNSS/PDR fusion algorithm specifically designed for the consumer-grade IMU, magnetometer, and GNSS receiver built into Apple Watch, tracking varied roll and pitch of the sensor caused by hand swing, and integrating a CNN model to predict the 1-D speed and provide ZUPT information, offering improved accuracy and reliability.

Published: May 2023

Abstract. This paper explores the use of Mobile Mapping Systems (MMSs) for urban Cultural Heritage (CH) documentation, which has become an increasingly important tool in surveying for rapid and accurate mapping of both internal and external environments. The study evaluates the performance of the STONEX® X120GO SLAM Laser Scanner, a recent commercial MMS, in documenting CH in various outdoor applications, including urban environments and inaccessible places. The methodology was applied to three test fields in the historic centre of Venice, which include Piazza San Marco, Santa Marta area, and the Venetian canal called Rio de le Toresele. The STONEX® X120GO SLAM Laser Scanner is composed of a 360° rotating head LiDAR scanner, three 5MP cameras, and an Inertial Measurement Unit (IMU) and Global Navigation Satellite System (GNSS) for geospatial 3D point cloud creation. The MMS was evaluated in terms of time, accuracy, and point cloud resolution against other active sensors such as Terrestrial Laser Scanners (TLSs) and spherical photogrammetry. The results suggest that the tested MMS has reached optimal levels of development, enabling high-speed data collection and providing good accuracy for significant urban CH sites. Overall, the paper highlights the importance and potential of MMSs for CH documentation and emphasizes the need for ongoing development to optimize the management process.

Abstract. Browsing the scientific and professional literature it appears that the concept of mobile mapping underwater is not as common as in ‘terrestrial’ applications. Nevertheless, exploring and mapping the ocean’s depths is a priority challenge for humankind, today more than ever. Radio waves, such as the GNSS or UWB signal, have a very limited transmission underwater, resulting in the absence of an underwater global positioning system. Consequently, the main sounding methods (i.e., depth measuring systems) are based on the fusion of inertial and acoustic sensors, which allow for systematic mapping of vast seafloor areas. However, photogrammetric surveying methods are preferred when high resolution and reliable colour information are essential aspects in the project economy. This class of approaches include visual odometry and visual SLAM (vSLAM), which represent a valid tool for navigation and positioning in GNSS-denied environments, such as underwater. In this paper, we present a portable underwater mobile mapping system, named FROG, which implements a vSLAM based solution to guide the survey according to photogrammetric principles. FROG is built upon the Guided Photogrammetry - GuPho concept and, thanks to its modular design, can be used by a diver or installed on a micro ROV and controlled remotely from a support vessel. In the paper, FROG characteristics will be detailed, and its potentialities demonstrated in real case applications at sea and in lakes.
