arcgis2geojson

✓ import arcgis2geojson

The module is used as a package; primary function is arcgis2geojson()

N/A

✓ from arcgis2geojson import arcgis2geojson

✗ from arcgis2geojson import ArcGIS2GeoJSON

Function is lowercase; class naming was common mistake in older versions

Convert a basic ArcGIS JSON FeatureSet to GeoJSON.

import arcgis2geojson # Convert an ArcGIS JSON FeatureSet (dict) arcgis_json = { "geometryType": "esriGeometryPoint", "features": [{"attributes": {"id": 1}, "geometry": {"x": -122.68, "y": 45.52}}] } geojson = arcgis2geojson.arcgis2geojson(arcgis_json) print(geojson) # Output: {'type': 'FeatureCollection', 'features': [{'type': 'Feature', 'properties': {'id': 1}, 'geometry': {'type': 'Point', 'coordinates': [-122.68, 45.52]}}]}

Debug

Known issues

gotchaThe function arcgis2geojson() expects a Python dict (parsed from JSON), not a raw JSON string. If you have a string, you must parse it via json.loads() first.

fix

geojson = arcgis2geojson.arcgis2geojson(json.loads(arcgis_json_string))

affects: all

gotchaArcGIS JSON with spatialReference.wkid (e.g., 4326) is not automatically reprojected; the library assumes WGS84 (EPSG:4326). If your data is in a different CRS, you must reproject before conversion.

fix

Manually reproject coordinates using a library like pyproj before passing to arcgis2geojson.

affects: all

deprecatedThe old experimental function 'convert' (from v2.x) was removed in v3.0. Use 'arcgis2geojson' function instead.

fix

Replace convert(...) with arcgis2geojson(...).

affects: >=3.0

Errors

Common errors & fixes

AttributeError: module 'arcgis2geojson' has no attribute 'arcgis2geojson'

Import performed as 'import arcgis2geojson' but the function may not be directly accessible due to shadowing (unlikely in current version) OR incorrect installation.

fix

Ensure you have arcgis2geojson installed (pip list) and import as 'import arcgis2geojson' then use 'arcgis2geojson.arcgis2geojson'. Alternatively, do 'from arcgis2geojson import arcgis2geojson'.

KeyError: 'geometryType'

Input dictionary missing the required 'geometryType' key. This is mandatory for ArcGIS JSON.

fix

Make sure your ArcGIS JSON includes 'geometryType' (e.g., 'esriGeometryPoint', 'esriGeometryPolygon').

TypeError: string indices must be integers

Passed a JSON string (str) instead of a dict to arcgis2geojson().

fix

Parse the string first: import json; arcgis_json = json.loads(json_string); geojson = arcgis2geojson.arcgis2geojson(arcgis_json)
