To ensure that territories are displayed correctly on the map and balancing can be performed successfully, geographic data must meet the requirements described below.
| Requirement | Description |
|---|---|
| Supported File Format | The file must be saved in GeoJSON format. If the file cannot be uploaded, make sure that:
If the file format is not supported or the file structure is invalid, the system displays an error message. |
| Coordinate System | Geographic data must use the WGS 84 (EPSG:4326) coordinate system. If the coordinate system is not explicitly specified, the data is interpreted as WGS 84. If objects are displayed in the wrong location after the file is uploaded, check the coordinate system of the source file. If necessary, export the data again using WGS 84 (EPSG:4326) and re-upload the file. |
| Valid Coordinate Ranges | All coordinates must be within the following ranges:
Coordinates outside these ranges may cause objects to be displayed incorrectly on the map. |
| Geographic Objects | The file must contain geographic objects with coordinates. Territory boundaries must be defined correctly. |
| Overlapping Territories | Territories must not overlap. Each point on the map must belong to only one territory. Overlapping territories may cause data to be processed incorrectly and may prevent balancing from being performed. |
| Territories Consisting of Multiple Parts | A territory can consist of multiple separate parts located in different areas. All parts can be treated as a single territory. If a territory name is specified in the uploaded file, it is used as the name of the corresponding object on the map. For a preliminary check of small GeoJSON files, you can use geojson.io. |
