GeoJSON is a file format for geographical data. 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.

  • Go to the documentation for ArcGIS
  • Go to the documentation for 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 conform to a number of prerequisites before it can be loaded properly. Files which do not conform to these prerequisites may not be loaded properly by the Tygron Platform. The requirements are:

  • 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.

Notes

  • Shapefiles can be converted to GeoJSONs using QGIS
