GeoJSON is a file format for geographical data (e.g. Polygons or Points). It is a simple text-based format which can be read by humans, but also by computers. Any Geo Dataset in another format can be converted to the GeoJSON file format.
How to create a GeoJSON file
To convert a Geo Dataset to a GeoJSON, a GIS (Geographical Information System) can be used. ArcGIS Desktop is one example. An open-source alternative is QGIS.
Also take a look at the data preparation page for considerations and tips regarding importing geo data.
Use the Geo Data Wizard for importing the created file. Select in step 1 the first option: Import a GeoJSON file and follow the steps in the wizard.
Import requirements
The GeoJSON file must meet the following requirements to be loaded properly by the Tygron Platform:
- The file must be saved in GeoJSON format.
- The file must have a CRS (Coordinate Reference System) defined.
- The file must use character encoding UTF-8.
- All desired attributes must be numerical, so that they can be loaded as valid attribute values. Attributes with text values are ignored when attempting to load them as attributes.
