- Open the source in QGIS. Keep related Shapefile files, such as
.shp,.shx,.dbfand any.prj, together. - Check the source’s actual coordinate reference system. If unknown, ask the data provider; do not simply assign WGS 84.
- On the layer, choose “Export → Save Features As”. Select GeoJSON and target WGS 84 / EPSG:4326.
- Export the required plots without unnecessary rounding and reopen the result to check locations.
- Upload the GeoJSON in the portal, review the preview and confirm the import.
