GeoVanguard QGIS 4 compatibility
QGIS 4 ready Active
Yes — GeoVanguard supports QGIS 4 (declared max version 4.99.0).
Open-source tools for large, complex remote-sensing and GIS data in QGIS — 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 — QGIS, GDAL/OGR, GEOS, NumPy and SQLite — 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 › GeoVanguard › 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 — 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. License: GPL-2.0-or-later.
