{"name": "GeoVanguard", "package_name": "geovanguard_qgis", "description": "Open-source tools for large, complex remote-sensing and GIS data in QGIS \u2014 including smoothing of polygon maps and classified rasters (e.g. Sentinel-2 land cover) without gaps or overlaps between neighbouring polygons.", "about": "GeoVanguard helps you process large, complex remote-sensing (RS) and GIS data in QGIS. It combines proven open-source components \u2014 QGIS, GDAL/OGR, GEOS, NumPy and SQLite \u2014 into efficient workflows that scale to very large datasets: the work is split into tiles and shared across your CPU cores, it can be paused and resumed, and an interrupted run continues where it stopped. Tools (Processing Toolbox \u203a GeoVanguard \u203a Smoothing Topology Preserver): Smooth Polygons smooths the outlines of an existing polygon map, such as land cover or forest types; Smooth Polygonization turns a classified raster into smooth polygons in one step. Neighbouring polygons share each smoothed border, so no gaps or overlaps appear, holes are smoothed like outer edges and areas are preserved \u2014 also for maps with hundreds of thousands of polygons. Choose Gaussian (recommended), Chaikin, B-Spline, Bezier or Douglas-Peucker smoothing; the defaults suit 10 m Sentinel-2 maps, with distances in meters. GeoVanguard needs nothing besides QGIS; the same engine is also available without QGIS as the Python package \"geovanguard\". Developed by Pisut Nakmuenwai.
