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.

10:00AM - 10:20AM Utilizing Geospatial Techniques and QGIS for Biology Research - Rusti Liner

Dillard University in New Orleans, LA is a historically black college/university and prides itself in utilizing innovative technology and tools in the classroom. The Biology Special Topics course (BIO 300) has been partnering with a professional Geographic Information Systems professional for the past two years to demonstrate this concept. The course is taught by Dr. Ruby Broadway, who is the principal investigator for the Interdisciplinary Urban Environmental Institute funded by the National Science Foundation, the Young Scholars Environment Institute, and the Integration of Technology and Virtual Laboratories. Dr. Broadway co-teaches with Professor Rusti Liner, a GISP and 27-year veteran of geospatial technologies and emergency management. Together, these partners form a dynamic duo of STEM and Social Sciences that offer students a unique perspective on how to accomplish Biology research, and QGIS is the centerpiece of this effort.

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

11:10AM - 11:30AM - Mapping Social Determinants of Health with TidyCensus - Dr. Dottington Fullwood

US Census data provides a multitude of variables to describe population-level characteristics at various geographic entities. Tidycensus developed by Kyle Walker allows data scientists to get simple feature geometry in a tidyverse-ready dataframe to visualize a select number of US Census Bureau's data. This presentation purpose will provide a broad overview of how to use pre-pared Census data for data exploration across census tracts, counties, and block groups.

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.

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
