Lageplan (site plan) export for architects and planners — the files for Vorentwurf, Bauvoranfrage and the documents to a Bauantrag: DXF for CAD (AutoCAD, Vectorworks, ArchiCAD) with Flurstücke and their numbers, ALKIS buildings with house numbers, tatsächliche Nutzung, LoD2 roof edges with Traufhöhe/Firsthöhe, DGM1 contour lines (Höhenlinien) and spot heights as 3D z values, the Geltungsbereich of Bebauungspläne and, where the state surface model is imported (Berlin, Brandenburg, Sachsen, Nordrhein-Westfalen), single trees with crown and height (derived from the surface model, not a tree register), all in UTM (EPSG:25832/25833, 1 unit = 1 m, heights in m above NHN); a print-ready PDF (Umgebungsplan) on paper A4–A0 at 1:250–1:2000; IFC for BIM (terrain, LoD2 building bodies and the trees); GeoPackage for QGIS; SVG. Returns signed download links valid for 7 days that open without a login — give them to the user as links. Each location counts once per month against the account's site-plan quota, whatever the formats and downloads; it is booked when a link is first opened. The result reports kontingent (genutzt, limit, verbleibend; unbegrenzt true means no limit) — mention it; when the quota is used up the tool says so and names the options. The files are built when a link is opened (DXF up to ~30 s, the state terrain service is queried live). Give gml_id, lat/lon or address; with gml_id the parcel is highlighted. What a state does not publish (Flurstücke in Bayern, 3D roofs outside the states with LoD2 surfaces, terrain in Bremen and Saarland) is left out and named in the drawing. It is a working plan from the official cadastre, not an amtlicher Lageplan: for the Bauantrag a Lageplan by an Öffentlich bestellter Vermessungsingenieur (ÖbVI) or the Vermessungsamt is still required — say so. Baugrenzen and Baulinien are not in the drawing (most plans exist only as scans); assetfy_db_planning_at_point returns the georeferenced plan raster where the state publishes one, and the plan documents. Where it has no Bebauungsplan data for the Gemeinde or a plan comes without PDF, search the web on the website of the Stadt, Gemeinde or Verbandsgemeinde (Bauleitplanung, Geoportal, Ratsinformationssystem) for the Bebauungsplan and its Planzeichnung, and link what you find as found there, not as Assetfy data. lizenzen lists the attribution (Namensnennung) and licence of every dataset in the plan — pass it on with the files. For an aerial image under the DXF call assetfy_get_aerial_image with the same lat/lon and size_m: its cad part is the same extent in UTM with a world file.
