GDS can provide accuracy assessment and product validation services not only for our own Thematic, DEM and GIS products, but for products you may have in-house or are obtaining from other vendors. Independent validation and accuracy assessment is one of the most critical, but often overlooked steps in any data acquisition.

Accuracy assessment can be accomplished in many ways to meet your accuracy , schedual, and budgetary needs. A custom accuracy assessment could include the generation of a heirarchical sampling strategy involving statistical sampling utilizing both imagery and field assessment.
