Bjørn Sandvik's Thematic Mapping Blog has only posted ii interesting tutorials on mapping grid-based statistics. Both tutorials too the accompanying demo maps visualize population density inwards Oslo, Norway.
The offset tutorial inwards Mapping Grid-Based statistics using OpenLayers, Three.js too D3.js shows you lot how to practice a grid based interactive map to visualize population density. The map likewise allows the user to guide an expanse on the map to encounter the set out of inhabitants inwards a custom defined area.
The instant map inwards the post provides a 3d visualization on the same population data, amongst each grid's population density shown equally a 3d tower or block on the map. The green occupation amongst such an approach is that the towers or blocks inwards the foreground obscure the stance of the towers inwards the background. Bjørn's 3d interactive map largely overcomes this occupation yesteryear allowing you lot to rotate too zoom inwards too out on the map.
Both the tutorials for the maps are inwards Norwegian but the root code is available on GithHub too should survive slow to follow for anyone familiar amongst OpenLayers too D3.js.
