GAP Data: Making It More Available
Track: Federal Government Systems
Author(s): M. P. Mulligan
Paper will discuss ongoing efforts by the USGS to make biological data it already holds more available via Internet technologies. As steward for the GAP program, USGS BRD has been in the process of assembling this data for more than a decade.
GAP data sets are coverages at roughly 1:100,000 scale that were assembled for each state (47 completed, some now in second iteration) as part of the GAP program for the identification of gaps in Bio-Reserve locations. It includes Arc Coverage layers on vegetation, landownership, and so forth, that may have broader application in planning and management. Many potential user communities are still unaware of its existence and possible utility. The state-by-state distribution of GAP data on CD has been uneven, and the USGS BRD is investigating technologies to make it more available; current prototyping focuses on ArcIMS 3.
