The application reads the EA geometry and attributes directly from the GeoJSON source. Internet access is required for remote data and map tiles.

02 Administrative selection

Local Government Area District Ward

Selecting an LGA, district or ward filters the EA layer and zooms the map to the selected geography.

Methodology and data notes

EA statistics are calculated from the attributes available in the loaded GeoJSON. Population density is calculated as population divided by EA area in square kilometres. 3D extrusion height is a visual scaling of the selected indicator and is not a measured building height. Missing or zero values are not treated as observed values. The map uses a fixed Esri satellite imagery layer with reference labels.
