summary

Shows how to build a working GIS app with GeoDjango: import a country shapefile using Django’s ogrinspect, load geometries into PostGIS as MultiPolygons, register the GeoManager, and expose editable geometry fields with the provided widgets. Renders shapes with OpenLayers (transforming EPSG:4326 to Google’s 3857/900913), supports contains and nearest‑N queries (example: five closest countries), and warns that some polygon distance ops can be very expensive.
