The official deadline for our Call for Presentations for the Spring Fling has passed on Friday March 10. However, if you have a topic you would want to present and need some extra days to submit an abstract just let us know. For the time being you can still submit proposals for talks/presentations via the web form. Please feel free to pass on to anyone you know who might want to give a talk!

Matt Stevenson will share a preview of his Spring Fling lightning talk about using R Studio to generate spatially balanced sampling sites for surveying the endangered Streaked Horned Lark in the Willamette Valley of Oregon.

Karsten Vennemannn will show a variety of live map demos (based on a web mapping viewer, internally called base viewer) he has worked on together with Eldan Goldenberg over the last 1.5 years. Base viewer is based on Openlayers (compiled via Node package manager), MapServer and PostGIS.

Ivan Storck will provide an update on the status of his work with Washington Water Trails to update their maps and is seeking some ideas to help out this local non-profit.

Anyone is invited to share (their own or news about any interesting) small or large geospatial projects. As always any geo-questions are encouraged and will gladly be discussed within the group.
