When using the Features API, it is important to follow specific rules to ensure your submissions are accepted and processed correctly. Below are the key requirements:
General Requirements
| Rule | Requirement |
| Format | Valid GeoJSON |
| Projection | WGS84 (EPSG:4326) |
| Dimension | 2D only (no 3D geometries) |
| Supported Geometry Types | Polygon or MultiPolygon |
| Vertices Limit | No more than 1,500 vertices |
| Total Collections Limit | Up to 1000 collections per organization |
| Total Features Limit | Up to 2 million features per organization |
| Collection Features Limit | Up to 150,000 features per collection |
Optional Features Properties
A Feature may contain any properties you wish to include. If you provide an id, it will be used as the feature’s identifier for lookups. If an id is not provided, one will be automatically generated. The total JSON payload for feature properties is limited to 3KB.
Important Notes
- Only two-dimensional (2D) coordinates are allowed — Z-values (elevation) are not supported.
- Submissions exceeding the vertex or feature limits may be rejected or result in processing errors.
- Ensure that all geometries are properly closed and valid according to the GeoJSON specification.
