Warnings

• breaking Support for Python 2.7, 3.4, 3.5, and 3.6 was dropped in version 1.0.0. Users on these older Python versions must use `geomet<1.0.0`.
  Fix: Upgrade your Python environment to 3.7 or newer to use `geomet>=1.0.0`. Alternatively, pin `geomet` to an older version if Python upgrade is not possible.
• gotcha Conversions involving EsriJSON, especially with coordinate value structures or custom SRIDs, had known bugs in versions prior to 1.1.0.
  Fix: Upgrade to `geomet>=1.1.0` to ensure correct and reliable GeoJSON to EsriJSON conversions, including proper handling of coordinate arrays and SRIDs.
• gotcha Previous versions of `geomet` (specifically before 1.0.0) had issues with handling floating point representation, particularly with exponential coordinate values, which could lead to subtle precision errors during WKT/WKB parsing and generation.
  Fix: Upgrade to `geomet>=1.0.0` for improved precision and robust handling of floating-point numbers in geospatial data conversions. If on older versions, carefully validate converted geometries.

Install

• pip install geomet Install stable version

Imports

• wkt

  from geomet import wkt

• geojson

  from geomet import geojson

• esrijson

  from geomet import esrijson

  The EsriJSON module is named `esrijson`, not `esri`.

Quickstart

This example demonstrates converting a WKT string into a GeoJSON dictionary and then dumping it back into a GeoJSON string using the `wkt` and `geojson` modules.

from geomet import wkt, geojson

wkt_string = "POINT (30 10)"

# Convert WKT to GeoJSON dictionary
geom_dict = wkt.loads(wkt_string)
print(f"WKT loaded as: {geom_dict}")
# Expected: {'type': 'Point', 'coordinates': (30.0, 10.0)}

# Convert GeoJSON dictionary back to GeoJSON string
json_string = geojson.dumps(geom_dict)
print(f"GeoJSON dumped as: {json_string}")
# Expected: {"type": "Point", "coordinates": [30.0, 10.0]}
