LandXML — Surveying & Civil Engineering Data Exchange

Preço antes do pagamento

.xml · application/xml

LandXML is an open XML vocabulary from the Autodesk, Bentley, and Trimble consortium (1999) for exchanging civil engineering and surveying data between AutoCAD Civil 3D, Bentley OpenRoads, Trimble Business Center, and Russian CREDO, IndorCAD, Topomatic. Our exporter produces a valid LandXML 1.2 document: buildings become Parcel elements with CoordGeom geometry, roads become PlanFeature from Line segments, and point objects become CgPoint. Honest about limits: coordinates are emitted in WGS84 (lat/lon), not a projection, so before designing in Civil 3D they must be re-registered to a local metric system (UTM, national grid). We write straight segments with no transition clothoids — OSM stores no curve parameters — so this is an OSM context basemap, not a geodetically verified survey.
