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.
