Gis data download

A data model in geographic information systems is a mathematical construct for representing geographic objects or surfaces as data. Gis data download are two approaches for representing three-dimensional map information, and for managing it in the data model.

Approaches for representing three-dimensional map information, and for managing it in the data model. This mapping approach characterizes the vertical variations of physical properties in each 3-D map unit. Raster-based stacked surfaces depict the surface of each buried geologic unit, and can accommodate data on lateral variations of physical properties.
