Not QGIS 4 ready Active
Not yet — the latest version declares max QGIS version 3.99.0, so it is not offered to QGIS 4 users.
QGIS plugin to convert elevation rasters into LandXML TIN surfaces and run quality control on the result.
About
Two Processing algorithms for moving terrain data between GIS and survey or CAD workflows. "Raster DEM to LandXML surface" turns any elevation raster into a LandXML TIN without intermediate mesh layers or extra plugins, with control over cell size, extent, linear units and a constant height shift. "Check LandXML surface (QC)" validates an existing LandXML file - structure, declared units, degenerate triangles, nodata leakage - and can compare it back against its source raster to report vertical bias, RMS and metre/foot mix-ups, writing the worst residuals out as a point layer.
