Welcome to State of the Map 2020
State of the Map is the yearly gathering of the global OpenStreetMap community. In 2020, forthe first time since ever the conference will not be held as an in-person conference, but as an
online conference. We are proud of the participation of the OpenStreetMap community andour rich programme but there is even more! Please do get involved and take advantage of theoff-schedule sessions, discussions and spaces.

A short history of SotM2020
In 2019 Bernelle Verster (indiebio), an experienced FLOSS community manager and conference
organiser put a lot of effort into formulating a detailed bid for Cape Town. She also managed
to rally a passionate local African team of volunteers around her. And would you believe that,
South Africa won the vote! The first SotM in Africa!
Fast forward to March 2020. Teams and committees already in an efficient routine of regularmeetings and organising tasks via GitHub issues with the conference date becoming more andmore emergent. The news of COVID-19 first lurking, then hitting the entire planet hard. South
Africans like to repeat words for emphasis: “Hard hard”.
With the consequences at that point being not quite clear, alternative paths were mapped
out. But eventually President Ramaphosa issued travel restrictions and a state of emergency
on March 15. A very strict lockdown following soon. What to do? Postpone to a later date in2020 with uncertainty? Cancel entirely? No, an online conference it’s going to be!
A new situation to all, we tried to uphold old traditions. We also tried to introduce things
that can contribute to a communal atmosphere, hence the distance. One of it being theself-organised sessions. Please find things like FAQ, session URLs, and links to ressources
at 2020.stateofthemap.org.
We thank our sponsors that stayed with us and help us organise this conference under free
software principles.
We wish you a wonderful timeYour organising team.

Drones for Community Mapping

Drone technology is an evolving industry used in multi-disciplinary fields ranging from agriculture, marine conservation to real estate and films. There’s so much potential and possibilities
on what drones could help people making work faster and more efficient. In mapping, aerial
imagery uploaded to Open Aerial Map can be used as basemap for OSM editing. Example
cases are in Batad Rice Terraces, UNESCO Heritage site for mapping tangible changes in thecommunity over time and create a tourism map and other small urban communities in thePhilippines, aerial imagery was used for mapathons and community mapping done in OSM.

4 County OSM Digitization Liberia – Lesson Learned

10:45
Track 2

Last year, HOT collaborated with OSM Liberia and iLab Liberia to complete the mapping andperform quality assurance in four counties in Liberia. The objective of this program is to update
OpenStreetMap data to assist with a Social Registry data collection in four counties in Liberia:
Bomi, Bong, Nimba and Maryland. Buildings and roads are the entities to map for this program.

OSM Routing Evaluation

This talk will present an evaluation of different OSM routing software and its impact on the journey. Several popular OSM routing software results will be evaluated on its route-cost (distance9and or time) and different modes of transportation (from walking to motor-vehicle). Additional
evaluation on the ground will also evaluate which route is a good (or bad) one and what may
cause this impact.
Sowmya Nayani

Track 2

Health Facilities Import
RMSI - India

The talk is to basically share the experience of working with Imports of Health Facilities in India(OpenGovernmentData). We planned to go briefly through the background of Open GovernmentData and the countries following the OGD, along with the compatibility of OdBL for thedatasets they provide to the public.
The main purpose of the import is to provide accessible data of accurate health care information from the Open Government Data directories for Hospitals, Health facilities, Blood banks,
Health Centers and Health Clinics information which can be useful for all the people and also
the Humanitarian team in India.
The primary focus of the talk is the import process from data preparation to the execution
which includesImports Guidelines , Data Cleanup, Data transformation, Data Execution. The
talk shares the detailed stats of the – Indian Health facilities OSM map data coverage before &after Imports and our survey experience for collecting the health facilities records in our region –Telangana.
We also line up with the Survey experience to collect the Health facilities records and conducted OSM awareness programmes. Conclude the session with the future plan and local
community support.

Adding Missing Ranking to OSM Data for Rule-based Cartography

Separation of features by their importance is a core technique in cartography. But what happens if features of the same feature class (e.g. train stations) have a varying importance? Amanual cartographer can choose the important features based on other knowledge. Howerver,
rule based cartography which is dominating in the OpenStreetMap environment cannot work
this way. A computer programme rendering a map needs selection rules. Someone has toimplement them.
This talk presents some examples showing how to add lacking relevance information if theimportance of features within one feature class ranges span between extreme values. It willshow how train stations and airports can ranked using other OSM data and external datasets.

Building mapping communities in rural Tanzania – challenges, successes and lessons learnt

13:00
Track 2

Crowd2Map Tanzania is a volunteer run crowdsourced project that has been mapping rural
Tanzania since 2015. This talk will give an overview of some of the lessons learnt, particularly inbuilding mapping communities in remote rural areas with first time smartphone users.
Said Turksever

Track 1The Map in 360

Mobile mapping is the process of collecting geospatial data from a mobile vehicle using a 360º
camera, laser scanner, GPS/IMU positioning system, and other sensors. This is one of the mosttime and cost effective methods to collect geospatial data, but the required equipment can be
expensive. An alternative approach to mobile mapping brings the opportunity to the OpenStreetMap community to ”‘Map in 360”’ using a wide range of consumer devices compatible
with Mapillary. Instead of capturing a frame of street-level imagery in a single direction, a360º camera can capture the entire scene simultaneously. 360º street-level imagery provides
the OpenStreetMap community a more comprehensive understanding of the map space andmore accurate machine-generated map data. In this talk, we will review the workflow of datacollection with 360º cameras, look at how to upload 360 street-level images to Mapillary, andcompare the impact of different 360º camera models in terms of map data extraction accuracy. OpenStreetMap communities can use this knowledge to coordinate their own street-level
imagery collection with 360º cameras to contribute to Mapillary and improve local maps.

Mapcampaigner Redesign: The Data Quality Monitor For OSM

16:30
Track 1

Humanitarian Openstreetmap Team (HOT) is an international team focused on humanitarian
action and community development through open mapping. Since 2010, the organization has
managed activations to attend multiple events such as understanding hazards, public health,refugee response, among others. However, when we think about organizing large-scale efforts
it can be complex, due to the necessary logistics, volunteers involved, and also assuring thatthe data collected is meaningful. MapCampaigner, is a tool which monitors progress, view
metrics on the quality and completeness of collected data and users engaged. The goal ofthis talk is to present the latest features included in the latest update of the tool, the goals
that MapCampaigner accomplishes and many humanitarian and non-humanitarian examples
through a demo.

Creating an open data ecosystem for reviews of places and more

16:30
Track 2

We built open-source infrastructure that allows the community to integrate open data reviewsof POI into the OpenStreetMap ecosystem. This enables any application or website to make useof a reviews layer, and to benefit from the shared data pool that is created by a combined userbase of participating applications. We built it to ensure that people all over the world can freely
share their insights about things that matter to them without being confined to proprietarydata silos.
Frederik Ramm

There might have been a misunderstanding...

17:15
Track 1

Common misconceptions about OpenStreetMap
When people come to OpenStreetMap for the first time, their expectations are sometimes atodds with what the OpenStreetMap community is doing. If you have been puzzled by an OSMer
telling you that OpenStreetMap is not a map, that openstreetmap.org is not aiming to competewith Google Maps, or by their stubborn refusal to remove a private trail from the map, then thistalk is for you. It will explain the basic tenets of the OpenStreetMap community and how they
apply in practice.

OSM data assessment in the area of Athens – Greece

17:15
Track 2Current presentation aspires to contribute to an overall assessment of the OSM map in Athens,
Greece. The OSM content is assessed in terms of completeness and precision. Various official
mapping sources and ground truth data are employed in order to measure the current state of
the map.

An Incomplete History of Companies and Professionals in OpenStreetMap

18:00
Track 1This talk with survey the bright and dark history of companies and professional involvement in
OpenStreetMap, lay out the challenges that we face now, and chart steps forward to figuring
this out together. I want to reset the vision of the position of companies in OSM, starting byconnecting back in time to when it was all more fluid in our community. Only later did somedraw a sharp distinction between volunteer and professional activities in our project. The
reality of the relationship of companies and professionals in OpenStreetMap from the very

13

earliest days until today is ... complicated. There’s incredible mutual benefit and purpose.
There are super hard issues to address when large amounts of resources are mustered, among
the constellation of many kinds of actors and motivations in OpenStreetMap. The reality isthat OpenStreetMap is transformative, and that companies in OSM first come for the data, may
fumble along the way, and stay for the shared mission to change how maps are made in theopen.

Turkish Law on National Geospatial Data and Its Implications Regarding OSM and the Community

18:00
Track 2The talk will focus on the Turkish law egulating the acquisition, collection, dissemination andtrading of spatial data falling within the responsibility matrix of Turkish National Geographic
Information System, effective since February 20, 2020. With the law, acquisition, collection,dissemination and trading of spatial data which is defined within the National Spatial Data
Responsibility Matrix by third party individuals or legal entities are subject to prior application
fees and approval of the Ministry of Environmental and Urban Affairs. The talk will reflect andreport the developments in Turkey after the law, effects and implications drawn focusing on
the national spatial sector, OSM, and the Turkish OSM community.

Participatory Budgeting & Mapping with citizens and government

20:00
Track 2

Map Kibera has been working for the past two years with some of Kenya’s county governments
to create maps of their primary features and funded projects. After implementing a Participatory
Budgeting process, these counties realized that without good maps it was difficult for people
to not only allocate resources, but to work with citizens to identify needs and prioritize funds.
Map Kibera has been assisting counties to map key features and projects in OSM by working
with youth from the local communities. The maps not only serve to connect citizens to thebudgeting process and hold county government accountable for the funded projects, but, they14

have also become central to county functions in all areas. This talk will share all about theprocess used and outcomes.

Sustainability and OSM for Development

20:45
Track 2

Research Outcomes with Open Cities Africa and GFDRR
We have seen an explosion of OSM mapping in the last few years around maps for development
and humanitarian uses, particularly in Africa. During this time it has also become clear thatsustaining this essential mapping work, and keeping maps up to date, was going to be a primaryconcern. Building a healthy mapping ecosystem around mapping for development will notnecessarily be able to follow the same model as it has in more developed countries. In thistalk, I will share the culmination of my research on sustainability with the World Bank’s Global
Facility for Disaster Reduction and Recovery and their Open Cities Africa project, and someways that we can best support mappers and grow a healthier global OSM ecosystem.

MapImpact: Mapping and social researchs by students in Cusco, Perú

21:30
Track 2

In Cusco, Peru, during the last 2 years, GAL Center worked with students using OSM and associated tools, such as Kobo as educational tools, mainly for research into social problems that the15students themselves identify in their locality. Projects such as ”‘Sexist advertising mapping”,”‘Sexual health” and ”‘Garbage mapping in Larapa” were the result of this work.
This year, MapImpact is one of the HOT Microgrants and we will work with high school
students and YouthMappers Chapters that we help to create in universities. In this talk, I will tell
you more about how we work MapImpact in GAL: our objectives, our methodology, our results
and why we would like it to be replicated in other places.

MAPBEKS: Mapping of HIV Facilities and LGBT spaces in the Philippines on OpenStreetMap

10:00
Track 1The Philippines is to be considered one of the most-LGBT friendly countries in the World. In
2019, it was able to host the largest pride celebration in Asia. Amidst all this, crimes against
LGBTQ+, discrimination, and bullying is still rampant in the country.
The Sexual Orientation and Gender Identity Expression (SOGIE) Bill is still continuously being
delayed. It is intended to prevent various economic and public accommodation-related acts of
discrimination against people based on their sexual orientation, gender identity or expression.
Despite of being tolerated, the LGBT community is still far from being accepted by society.
Evidence of our community have been written on books, told in stories, presented in movies
and yet the community has not left its mark in data. Spreadsheets, research, books haveidentified spaces where community activities happen but this are not shown on any map online.
Our spaces are mere descriptions or addresses on tables and paragraphs.
This talk would be about how we would be more represented on OpenStreetMap so as toprovide emphasis on being on the map.

OSM Deep Facts in Developing Country: Indonesia case study

10:45
Track 1

The number of OSM contributors every year tends to increase. But not all are sustainable contributors. For example in Indonesia, there is a lot of OSM training and Mapathon but it issuspected that there are not many local contributors of all time. For this reason, extracting
information from OSM accounts that have been registered since a few years ago that classified
as a rare mapper. The method is by recording the top 500 accounts in Indonesia, identifying
local accounts based on profiles and heatmaps, sending questionnaires, and summarizing

17them. The results can be used by the Indonesian OSM community to increase the sustainabilityof the contribution of local people in OSM.
Ardie Orden

Measuring OpenStreetMap building footprint completeness using human settlement layers

10:45
Track 2

Non-government organizations and local government units use geographic data from OpenStreetMap (OSM) to target humanitarian aid and public services. As more people start to dependon OSM, it is important to study data completeness in order to identify unmapped regions sothat OSM volunteers can focus their attention on these areas. In this study, we propose amethod to measure the data completeness of OSM building footprints using human settlements
data.
Zainab Ramadhanis

Gender Performance in OSM Mapping, Does It Matter?

11:30
Track 1Plenty of research about behavioural differences between men and women for years ago. According to a scientific article in 2013 by Lewis, on average women may have better verbal
memory and social cognition, whereas men may have better motor and spatial skills. Moreover,spatial skill is really needed for mapping, especially as a mapper volunteer in OSM that everyone
can make their own map. It also has been known that male mappers more dominate OSM
mapping than female mappers. Nevertheless, in some mapper communities, the number offemale mappers more than male mappers, for example in Humanitarian OpenStreetMap Team
Indonesia. 19 from 30 mappers in HOT Indonesia are female, yet does it affect the performanceand quality of mapping in OpenStreetMap?
Aphiwe Madubedube

Towards understanding the quality of OpenStreetMap contributions:
Results of an intrinsic quality assessment of data for Mozambique

11:30
Track 2Contributors of OpenStreetMap data for Mozambique, a country in Southern Africa, were classified into four distinct groups. The most active group included 25% of all contributors, mostof them long-term contributors, and most features were last edited by members of this group.
One can therefore conclude that the quality of the data is likely to be good, however, it lacks incompleteness and the number of edits per feature is low. Even though no absolute statements
about data quality can be made, the analysis provides valuable insight into the quality and caninform efforts to further improve the quality.

Identify map problems in OSM by connectivity check

12:15
Track 1

In an ideal map, every point is reachable to another. However, in OSM data for instance, only
98.59% of Singapore’s nodes are reachable to each other by a path. In this talk, we identify
OSM map problems by checking the connectivity of the road network using strongly connectedcomponent algorithms and introduce a creative visualisation to help map ops pinpoint the fix
effortlessly. Using this approach, we have fixed thousands of map problems in SEA.
Susanne Schröder-Bergen

12:15
Track 2Analyzing the localness of OSM data

The ”‘localness” of data is often described as a major factor for the authenticity of (geo-) information in OpenStreetMap. However, the exact meaning and relevance of ”‘localness” remain
controversial. We compare proposals made for the ”‘measurement”, i.e. for the empiricaloperationalization, of ”‘localness”. Based on this, two convincing operationalizations wereselected and implemented in order to contrast regional differences in ”‘localness”. Our analysis
allows the identification of regions in which exceptionally high proportions of data are mapped
remotely – mostly regions in the Global South. Bearing this in mind, we discuss how ”‘localness”
is negotiated in the OSM community.

The use of OpenStreetMap within the Italian Alpine Club

13:00
Track 1

The collaboration between the Italian Alpine Club (CAI) and OpenStreetMap (OSM) officiallybegan with the signing of an agreement between CAI and Wikimedia Italia, the Italian chapterof the OSM Foundation, in 2016.
The first activity was to define a standard to be used for CAI objects to be mapped using thewiki, and this started the mapping.
Three years after that signature much has been done with a surge in the last year also thanks
to the funding of CAI through the project ”‘CONTRACT FOR THE DATA IMPLEMENTATION SERVICE
IN THE INFOMONT SYSTEM”’. This financed one person to carry out different activities:- the data entry in OSM with the procedure used and the situation region by region- the development of software released under a FOSS license able to obtain CAI data from
OSM and carry out some conversion and reporting operations- training activities in the different sections of the CAI
During the presentation will be made a history of the activities of the CAI with OSM, theresults obtained so far and the various features of the software developed.

From Historical OpenStreetMap data to customized training samples
for geospatial machine learning

13:00
Track 2

Recently, OpenStreetMap (OSM) shows great potentials in providing massive and freely accessible training samples to further empower geospatial machine learning activities. We developed aflexible framework to automatically generate customized training samples from historical OSM
data, which in the meantime provide the OSM intrinsic quality measurements as an additionalfeature. Moreover, different satellite imagery APIs and machine learning tasks are supported
within the framework.

Community mapping a means to building resilience

15:00
Track 2The study contributes towards some best practices of carrying out community mapping exercise
and, distribution of results freely on OSM and spatial data portal like MASDAP for further studies
or decision making. Thus the study focused on preparing for mapping – what to map, how to
map and how to record the data; the mapping exercise itself; downloading and digitizing ofdata in map production; and how to use the maps to aid in decision making.

Earthquakes and OpenStreetMap

To assess the possible human and financial losses of earthquakes and to estimate the long-term
earthquake risk that many people on Earth are exposed to, detailed knowledge of buildings
is paramount. This encompasses not only the position, size, and type of buildings, but also
the reconstruction value and the number of people inside the building at any time. Using
OpenStreetMap data and further open data, we are implementing an open, global, dynamic,
purely algorithmic, and reproducible exposure model for the probabilistic description of the20

aforementioned parameters for every building on Earth, growing and changing with every edit
in OpenStreetMap.

Examining spatial proximity to health care facilities in an informal
urban setting

15:45
Track 2This study explores the following research questions using OpenStreetMap-based mapping
approach and healthcare facility survey from one of seven slums being studied in Africa andAsia. What are the differentials of spatial proximity to health care providers in informal settlements like slum? What are some of the lessons learnt from using OpenStreetMap-based
mapping approach for slum health research? Preliminary findings suggest that residents canaccess four categories of healthcare facilities (Clinics/Maternity Centres; Patent Medicine Stores;
Traditional/Faith Healers; Eye Health Centre) within a walking distance (under 1km) where

What to do when local citizens do not consent? A discussion on how tonavigate difficult field scenarios that involve local communities.

Track 1

Most field program managers have their go-to field preparation checklist – this often includes
a data model, their preferred data collection tools, field survey timeline, to name a few. We
are often cautioned about the importance of community entry, and it is right, you will not beable to just enter the community and start mapping as people will get curious, ask questions
and possibly become suspicious or hesitant to accept your data collection activities. At HOT,
we employe participatory mapping methods and encourage local people to map their communities. However, sometimes with even all the correct steps followed, your activities can behindered due to factors outside of your control. In this session, we will explore one of HOT’s
field mapping projects implemented in Kampala in collaboration with the Kampala Capital City
Authority that aimed to map community-level flood risk in a local suburb along the Nakamiro
Channel catchment area. Despite all the correct steps taken, community entry in a specificjurisdiction felt impossible and field mapping could not be carried out. In this session, our aim
is to first discuss what went wrong and how our field team approached this situation and later
invite participants/attendees to share similar challenges experienced in the field and how thesesituations were overcome or addressed.

Evolution of humanitarian mapping within the OpenStreetMap Community

16:30
Track 2Since 2010 organized humanitarian mapping has evolved as a constant and growing element of
the global OpenStreetMap (OSM) community. We analyse the history of humanitarian mapping
using OpenStreetMap History and OSM Tasking Manager (tasks.hotosm.org) data. We conduct acomprehensive quantitative analysis on a global scale and long term perspective to depict morethan just snapshots of individual events. Results show that in regard to edits, users, projects,
geographic diversity, almost all of these have experienced linear growth. But regarding user
commitment and validation efforts we conclude that the humanitarian mapping community
still faces huge challenges to achieve sustainability.

Detecting informal settlements via topological analysis

17:15
Track 2

We outline methods for a) extracting the geometry of street blocks in urban centres using OSM
and remote sensing data, b) generating approximate cadastral maps of a block given containedbuilding footprints, and c) quantifying residents’ ability to navigate within blocks throughtopological analysis of cadastral maps. This topological metric, termed ”‘spatial accessibility”
and denoted k = 1, 2, 3, ..., determines whether areas of a city are informal settlements, as
blocks where k > 2 contain cadastral parcels without direct access to formal road networks. We
analysed 1 terabyte of OpenStreetMap data for 120 low and middle income (LMIC) countries.

Curious Cases of Corporations in OpenStreetMap

18:00
Track 2

Today, nearly 17% of the global road network was last edited by a corporate data-team member.
We further investigate unique editing patterns among three corporations that have specific,
localized impacts on the map.

Pedestrians First

Measuring walkability in cities worldwide
Walkability is the foundation for urban life that is sustainable, inclusive, healthy, and dignified.
Pedestrians First is a new open-source suite of tools for using OSM data to measure indicatorsof urban walkability. During this talk, we will examine the nature of walkable and unwalkablecities, we will discuss the opportunities and limitations of using OSM to measure walkability,
and we will consider possible avenues for extending Pedestrians First in the future.
