STEMgis consists of three components:
- data loader, management and archive system
- retrieval and multidimensional visualization and analysis tool
- data dissemination including a freely distributable version of the
Viewer (STEMgis FreeView)
All spatial and attribute data are stored within STEMgis databases.
Every spatial feature and attribute value is stored with a time stamp
and a unique identifier. The spatial definition of a feature may change
with time, for example, the position of a car or the meandering of a river.
