==Speakers Dec 1st 2022==
8:30 AM - 9:00 AM - Doors Open/Registration 
9:00 AM - 9:05 AM - Opening Remarks - David Wright, Dean of Research & Graduate Education, College of Arts & Sciences
9:05 AM - 9:10 AM - Welcome from Organizers - Natalie Robbins, Stacy Curry-Johnson, & Randal Hale
9:10 - 9:50 Serve Data, Not Services - Howard Butler - Hobu, Inc
Gone are the days of buying a 2U server and sticking it in a rack in a closet next to an air conditioner. What was once organizational excess compute capacity to provide on-demand network services is now metered and measured in the cloud by the same administration that inventories the office supply cabinet. Excessive middleware is decidedly out of fashion, and concepts like Cloud Native Geospatial, with its focus on cloud optimized formats and JSON metadata to drive desktop and cloud applications alike are taking hold. Howard Butler, president of Hobu, Inc. and leader of the PDAL software project, will talk about formats, organization, federation, archive, and frustration in the process of getting data to and from the cloud.
Howard Butler is the founder and president of Hobu, Inc., an open source software consultancy located in Iowa City, Iowa that focuses on point cloud data management solutions. He is an active participant in the ASPRS LAS Committee, a Project Steering Committee member of both the PROJ and GDAL open source software projects, a contributing author to the GeoJSON specification, creator of the Cloud Optimized Point Cloud format, and a past member of the OSGeo Board of Directors. With his firm, Howard leads the development of the PDAL and Entwine open source point cloud processing and organization software libraries.
9:50AM - 10:00AM - BREAK
10:20AM - 10:40AM TiPG: Composable application for serving OGC Features and Vector Tiles from PostgreSQL - David Bitner
This presentation will introduce TiPG (previously separate packages TiMVT/TiFeatures) a minimal configuration Postgres based OGC Features and Vector Tiles server. TiPG can be placed in front of any PostgreSQL instance automatically exposing tables, views, and functions through the OGC API. Being build on FastAPI, TiPG can be either used directly as an application, or it can be incorporated as routes within any FastAPI application allowing to leverage the full FastAPI ecosystem for functionality such as Authentication or to extend the API with business specific needs.
10:40AM - 11:00AM Building a modern Cloud GIS with the Power of Open Source - Bernie Drahola & Daniel Anselmo
Configuring an online GIS solution can be challenging. Even though all the tools to do so are readily available. Bernie Drahola and his team want to provide GIS users around the globe a shortcut to using Open Source technology in the cloud at a low cost. Based on components like Openlayers, GDAL, GeoServer, and more they built yey'maps - a ready-to-use cloud GIS solution. In this presentation, you will learn about the journey of building yey'maps and its success story.
11:00AM-11:10AM BREAK
11:30AM to 11:50AM Mergin Maps for Archaeology, a QGIS workflow for field recording at the Vaughn Home Excavations, Vanderbilt University. - Giles Spence Morrow and Steven Wernke 
Methods of data collection in archaeological fieldwork settings vary as widely as the contexts themselves. Quite apart from core research questions, logistical and environmental conditions often guide how data is collected from archaeological contexts. The last decade of research has seen increasing interest in moving beyond analog documentation through personal notebooks and standardized paper forms to digital native data collection via iPads. With the advent of mobile GIS applications, on-site spatial documentation is now becoming a viable option in the field, allowing for real time data collection and collaboration across multiple members of an excavation project. The current paper outlines our ongoing use of the MerginMaps / Input App during the archaeological excavations at the Vaughn Home, one of the original faculty houses on Vanderbilt University’s campus. We will present our database structure and current workflow that integrates the MerginMaps plugin for QGIS to incorporate photogrammetric orthomosaics and LiDAR-based models created in the field. We highlight both the challenges faced and successes realized in our use of MerginMaps in our archaeological application of the software, with hopes of prompting discussion on future directions for development in relation to the integration of three-dimensional spatial data in the form of GLB models.
11:50AM -12:10PM STAC software, now and looking forward - Peter Gadomski
A tour through the current state of the software ecosystem around the SpatioTemporal Asset Catalog (STAC), and some discussion about future plans and roadmaps.
12:10 to 1:00 - LUNCH
1:00PM - 1:20PM - Vector Mosaicking with GeoServer - Joseph Miller
The vector mosaic datastore is a new feature in GeoServer that allows indexing many smaller vector stores (e.g., shapefiles, FlatGeoBuf) and serving them as a single, seamless data source. This has the advantage of cost savings when dealing with very large amounts of data in the cloud, as blob storage bills at a fraction of an equivalent database. It is also faster for specific use cases, e.g, when extracting a single file from a large collection and rendering it fully (e.g. tractor tracks in a precision farming application). This happens because the file splitting de-facto imposes an efficient data partitioning, and shapefile access excels at returning the whole set of features (as opposed to a subset).
1:20PM - 1:40PM - OpenStreetMap: The Community Behind Your Open Map Data - Maggie Cawley 
What motivates over 1.5 million people to add details to a single map? From improving Lyft user experience to saving lives during humanitarian crises, OpenStreetMap is an open source project that has altered the geospatial data landscape by providing free, editable open data to people all over the world. This talk provides an overview of the OpenStreetMap project, covers a few of its almost limitless use cases, and provides a behind the scenes look at the community driving the movement.
1:40PM - 2:00PM Using OSMnx to download global geospatial data - Matt Travis
At addresscloud we've been looking at ways to programmatically download the building footprints from OpenStreetMap (OSM) for various global cities. To do this we leveraged the awesome power of OSMnx, a simple yet effective python script that allows the user to extract not only real-world street networks but other geometries that exist in OSM. is built on top of geopandas. This presentation will talk about what's possible with OSMnx and demo its capabilities
2:00PM - 2:10PM BREAK
2:10PM to 2:30PM Extending GeoNode to Support Crowdsourced Historical Map Georeferencing - Adam Cox
For my master's thesis at Louisiana State University, I created a public web platform for crowdsourced georeferencing of historical maps. I decided to build from the geospatial content management system GeoNode, creating my own extension that allowed users to georeference GeoNode content in the browser, turning scanned documents into geospatial layers. To test it all out, I hosted the platform on oldinsurancemaps.net and solicited public participation. I connected it to the Sanborn map collection at the Library of Congress and participants georeferenced 140 volumes (1,500 individual sheets) of fire insurance maps from all across Louisiana. In this presentation I will describe my experience with GeoNode, show some results from the pilot project, and conclude with an update on where I've been taking the project recently
2:30PM to 2:50PM - OSGeoLive Tour Q&A - Brian Hamlin
OSGeoLive is a self-contained bootable DVD, USB thumb drive or Virtual Machine built on Lubuntu/GNU Linux, that allows you to try a wide variety of open source geospatial software without installing anything. -link- It is composed entirely of Libre software, enabling it to be openly distributed, duplicated and passed around. Source code is available. OSGeoLive provides pre-configured applications for a range of geospatial use cases, including storage, publishing, viewing, analysis and manipulation of data. It also contains sample datasets and documentation.
2:50 to 3:00 PM Break
3:00PM - 3:20 Using ESRI's File Based Geodatabase and QGIS - Randal Hale

9:00 to 9:40 State of Geoserver - Andre Aime - Geosolutions
GeoServer is a web service for publishing your geospatial data using industry standards for vector, raster and mapping, as well as to process data, either in batch or on the fly. 
GeoServer powers a number of open source projects like GeoNode and geOrchestra and it is widely used throughout the world by organizations to manage, disseminate and analyze data at scale.
This presentation provides an update on our community as well as reviews of the new and noteworthy features for the latest releases. In particular, we will showcase new features landed in the past year, including the newly released GeoServer 2.22, and glimpse of what’s in store for GeoSever 2.23.
Attend this talk for a cheerful update on what is happening with this popular OSGeo project, whether you are an expert user, a developer, or simply curious what GeoServer can do for you.
9:40 to 10:00 BREAK
10:00AM - 10:20AM - What's new in the Second Edition of Discovering QGIS 3.x - Kurt Menke
The Second Edition of Discover QGIS 3.x was published in August of 2022. The book is current to QGIS 3.26, includes 7 new chapters and a lot of new material. In this talk I will go through all the changes and what you will find in the Second Edition!
10:20AM - 10:40AM - Cartography for Academic Journal Figures & Books - Michelle Tobias
How do you communicate nuanced academic research in a post-it sized map? Making map figures for academic publications such as journal articles and books requires a different set of skills from making other maps. Space, color palette, and fonts are usually extremely limited and if you don't meet the requirements, you risk the journal staff editing your work which can alter data. In this talk, I will discuss how to find and understand art specifications from publishers and how to create maps that fit these specifications.¬†I will also discuss communicating effectively through small maps with limited color palettes. Demonstrations will take place in QGIS.
10:40-11:00 am- OpenRiverCam: open-source and free software to measure river flows with video recordings - Hessel Winsemius & Stephen Mather
pyOpenRiverCam is a fully open-source, user-friendly, low cost and sustainable python API to estimate river surface velocities and cross-section river flows. It is ideal to measure pre- and post-river restoration effectiveness, flows around infrastructure, and establish and maintain river rating curves (relationships between geometry and river discharge) in small to medium sized streams. The software is co-designed with practitioners from The Netherlands (Waterboard Limburg and KNMI) and Tanzania (Wami - Ruvu Basin Authority and TMA) and inputs from several users in the hydrometry and geospatial world. 
We will show and demonstrate the methods in pyOpenRiverCam (see https://github.com/localdevices/pyorc). The library performs lens calibration, image enhancement, stabilization, orthorectification, velocity estimation (with Particle Image Velocimetry), spurious velocity filtering discharge estimation, and intuitive plotting and exports in geographical projection or camera perspective, all through a highly intuitive Application Programming Interface. Validation shows a remarkable resemblance of estimated velocities against in-situ Ott mill observations. Application during the 2021 flood event in Limburg led to a full set of rating points (relationship between discharge and water level) within one single event. Full documentation is underway on https://openrivercam.org/ and first designs of an operational dashboard built on top are being made.
pyOpenRiverCam makes it possible to include OpenRiverCam methods in university curricula, or use it in research into enhancements or applications, as its methods are fully open, transparent, and easy to use. First cases for uptake in scientific education and research are taking place in the Netherlands, where pyOpenRiverCam is used in MSc studies and piloted with Rijkswaterstaat for several use cases, investigations on applicability of the method for flash flood monitoring in the Philippines. A first introduction with hands-on experience was provided to several stakeholders in Zambia, such as the University of Zambia, and the Water Resources Management Authority. We welcome use, feedback and contributions.
11:00 - 11:10 Break
11:10AM - 11:20AM - GeoServer in Action: discovering GeoServer production sites - Andrea Aime
