Currently, Podaris supports the WGS84 Coordinate Reference System (CRS). Attempting to import a GeoJSON dataset with a CRS other than WSG84 will produce an **"0" must be less than or equal to 180** error. ![CRS error](https://support.podaris.com/hubfs/image-png-May-06-2022-03-04-25-56-PM.png) A number of tools exist for identifying the CRS of a dataset when it is unknown, and transforming its data into a new CRS. - [MyGeodata Convertor](https://mygeodata.cloud/converter/geojson-to-latlong) - an online tool for identifying a dataset's CRS and converting it. - [A guide to saving a dataset in another CRS](https://docs.qgis.org/3.22/en/docs/training_manual/vector_analysis/reproject_transform.html#moderate-fa-saving-a-dataset-to-another-crs) with the free, open source and cross-platform GIS tool [QGIS](https://www.qgis.org/). -
