GeoLibre v3.0.0 is here! GeoLibre is a free and open-source, lightweight, cloud-native GIS platform for visualizing, exploring, and analyzing geospatial data. It runs everywhere you do, in the web browser, on the desktop, on mobile, and inside Jupyter notebooks, all while keeping your data local and private. This release landed 95 pull requests from 11 contributors, and 5 people made their first contribution to GeoLibre. Thank you to everyone who filed an issue, reviewed a change, or sent a patch. Our first major release makes the Cesium 3D globe a full rendering engine for the whole workspace, brings time-dynamic CZML scenes and native KML to the globe, and lets you save your edits straight back to ArcGIS Feature Services. What's new in v3.0.0 - Cesium as your main map: switch the entire workspace between MapLibre 2D and Cesium 3D from the View menu, and the choice is saved with your project. - Nearly every layer on the globe: COGs, PMTiles, MBTiles, vector tiles, ArcGIS services, I3S scene layers, LiDAR point clouds, and Gaussian splats all render in 3D, with extruded polygons and true elevation for 3D vectors. - Dynamic 3D scenes: load CZML for orbits, trajectories, and moving objects that play along the globe clock, open KML and KMZ with their original styling, and add Cesium Ion assets such as OSM Buildings by id. - Your tools work in 3D too: screenshots, print layouts, video and camera tours, the Elevation Profile, and the Sun, Atmosphere, Flight Simulator, and weather plugins. - ArcGIS write-back: edit a Feature Service layer in GeoLibre and save additions, changes, and deletions back to the service. - Editable SVG print layouts: export a layout and fine-tune the title, legend, and scale bar in Inkscape or Illustrator. - Smarter rasters and new data sources: viewport-based raster stretch, persistent layer filters from Select by Expression, a Portolan catalog browser, OGC CSW catalog search, and a USGS NLDI panel for tracing river networks.
