4D Geographic Information System (GIS) data

It is interesting to observe that, vendors are focusing on the development of 4D GIS software. 4D GIS data includes 2D data, 3D data, and data regarding time change. An integrated database with real-time monitoring is required to generate 4D data. 

4DMapper is an Australia-based company that puts multi-source and multi-format geospatial data, including 3D and 4D GIS, on the cloud and streams it to browsers after rasterization and vectoring.
