In 2015 or thereabouts I took a full semester course… Continue reading Linked In Learning →

I know I've been super behind on updating my QGIS software. I stuck to 2.18.19 for the last couple years because I don't like changing versions mid-project, but it's beyond time now. A stable release of QGIS 3 has been available since 2018, and I moved to version 3.8 a few weeks ago. The difference… Continue reading QGIS 3 Software Update →
