Bjørn Sandvik's Thematic Mapping Blog has only posted 2 interesting tutorials on mapping grid-based statistics. Both tutorials as well as the accompanying demo maps visualize population density inwards Oslo, Norway.
The kickoff tutorial inwards Mapping Grid-Based statistics using OpenLayers, Three.js as well as D3.js shows yous how to exercise a grid based interactive map to visualize population density. The map equally good allows the user to pick out an surface area on the map to meet the set out of inhabitants inwards a custom defined area.
The instant map inwards the postal service 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 commons employment amongst such an approach is that the towers or blocks inwards the foreground obscure the sentiment of the towers inwards the background. Bjørn's 3d interactive map largely overcomes this employment past times allowing yous to rotate as well as zoom inwards as well as out on the map.
Both the tutorials for the maps are inwards Norwegian but the rootage code is available on GithHub as well as should travel tardily to follow for anyone familiar amongst OpenLayers as well as D3.js.
