The Cascadia Users of Geospatial Open Source (CUGOS) is a Pacific Northwest group with members who are users and promoters of open source geographic information system (GIS) software and applications. Members come from all walks of life, including a large spectrum of business and academia, and active Open Source Geospatial Foundation (OSGeo) members (board members, charter members, and active project participants). CUGOS meetings take place the third Wednesday of every month at 6:00 PM.
The CUGOS 2023 “Spring Fling”, a conference showcasing recent research and applications using open source GIS technology, took place on April 21 (main conference) and 22 (OpenStreetMap Hackathon-OpenSidewalks Project) at the UW Bill & Melinda Gates Center for Computer Science and Engineering. The keynote speaker was Paul Ramsey, one of the original and lead developers of the PostGIS spatial data storage and analysis extension for the free and open source SQL database application, PostgreSQL.
CSDE research scientist Phil Hurvitz presented a talk, “Using R Markdown to create self-documenting research reports, including geospatial analysis and tabular, graphical, and map outputs” that included an overview of using R and PostGIS analytic approaches with code and results contained within HTML documents generated with R Markdown. Presentation materials are available at http://gis.washington.edu/phurvitz/presentations/2023/cugos_2023/, with slides and results of a simple demonstrative analysis of race and poverty combining US Census and City of Seattle GIS data. The web site includes downloadable code including R Markdown for generating slides and web pages and parallel analytic code using R’s sf package and spatial SQL with PostGIS.
