The 3D Geomatics* Committee (3DGeo) of the Minnesota Geospatial Advisory Council works to identify and promote the need for planning, funding, acquisition, and management of three-dimensional geomatic data and derived products. The committee engages multiple disciplines in Minnesota for the benefit of its resources and citizens, promoting the value, importance, and use of this complex and voluminous three-dimensional information.
* Geomatics: the discipline of gathering, storing, processing, and
delivering spatially referenced geographic information
