LandXML Road & Terrain GIS Tools QGIS 4 compatibility
QGIS 4 ready Active
Yes — LandXML Road & Terrain GIS Tools supports QGIS 4 (declared max version 4.99.0).
Civil 3D, OpenRoads and generic LandXML in QGIS: terrain, road geometry, profile and cross-section viewers, earthworks quantities, design reports and a geometric design review (alignment phasing, sight distance, barriers) against Kenya RDM 1.3 or AASHTO.
About
Brings LandXML road and terrain data into QGIS and turns it into review-ready reports. Import: TIN surfaces to GeoTIFF, surface boundaries, breaklines and feature lines; horizontal alignments with true arc-length stationing; vertical and existing-ground profiles; 3D centrelines; station points; Civil 3D corridor cross-sections placed along their alignment; a Complete Road Design GeoPackage export. Review and report: a Profile Viewer dock (click an alignment to see existing ground against design, with cut/fill shading, transitions and a cross-section tab); cut/fill, corridor and TIN-to-TIN quantities with mass haul and side-slope areas for grassing; cross-section sheets as PDF, HTML or PNG; a Road Design Report with plan, curvature, gradient, long-section and superelevation diagrams. Geometric Design Review: checks alignment phasing, stopping sight distance, crest and sag K, grades, radii, transitions, superelevation, design speed changes and embankment barrier warrants against Kenya RDM 1.3 (2025) or AASHTO 2018 criteria files, follows the design speeds set in Civil 3D, and writes recommended PVIs and curve lengths as a Civil 3D profile text file and LandXML. Coordinate handling is explicit: stored coordinates, axis swap, offset, 2-D Helmert or reprojection are chosen by the user; a LandXML-declared CRS is shown for reference only. US survey feet, international feet and metres remain distinct. No extra Python dependencies. Licensed under the GNU General Public License version 2 or later.
