dwg2geo (Python)
Convert engineering DWG drawings to GeoJSON from Python — the pure-Rust dwg2geo converter as a native extension. No AutoCAD, no LibreDWG, no GDAL needed.
pip install dwg2geo
import json
import dwg2geo
result = dwg2geo.convert_file("drawing.dwg") # or dwg2geo.convert(raw_bytes)
fc = json.loads(result["geojson"]) # GeoJSON FeatureCollection (local drawing coords)
print(result["feature_count"], "features")
print(result["converted"]) # per-entity-type counts
print(result["skipped"], result["failed"]) # with reasons — auditable
Options: convert(data, polygonize_closed=False, curve_tolerance=None).
The result dict mirrors dwg2geo's EmbedResult:
| key | meaning |
|---|---|
geojson |
FeatureCollection string in the drawing's local coordinates |
feature_count, model_space_entities |
totals |
converted / skipped / failed |
per-entity-type outcomes with reasons |
warnings |
conversion warnings |
bbox |
[minx, miny, maxx, maxy] or None |
source_sha256 |
hash of the input bytes (audit trail) |
Features carry resolved CAD style metadata (layer, color_rgb, color_index, linetype, lineweight_mm, text properties…). Coordinates are local — georeference with e.g. pyproj using the drawing's known CRS; dwg2geo never guesses one:
from pyproj import Transformer
transformer = Transformer.from_crs("EPSG:31983", "EPSG:4326", always_xy=True)
lon, lat = transformer.transform(x, y)
Deterministic: the same bytes always produce byte-identical GeoJSON on a given platform (across platforms — native vs WebAssembly — a few floating-point values may differ in the last digit).
