Description:
Abstract:
Statewide gridded layer providing coded to indicate distance to surface water bodies such as lakes and streams. Grid cells are coded to reflect distance ranges of 0-40, 41-70 and 71-100 meters from the nearest water body.
Purpose:
The PA Gap Analysis habitat models are compared in a collective manner to the distribution and extent of lands serving long-term conservation purposes. Mismatches of a substantial and extensive nature are identified as broad-scale "gaps" in the conservation safety net. Gap analysis is a "coarse filter" geographic approach to conservation, and is meant to supplement rather than supplant detailed work on a site level for species of special concern.

Process_Step:
Process_Description:
PADOT streams layer was converted to a gridded version covering the entire state. This was combined with surface water information from the available MRLC land use/land cover layer. Using the DISTANCE function of ARCINFO GRID a map was created showing distance to the nearest water bodies in 30-meter increments. This map was recoded (RECDIST) to reflect the final distance ranges.

Process_Step:
Process_Description:
Using the ARCINFO DISTANCE function from the 100 meter buffers in the streambufers100 layer distances were coded at 30-meter intervals. This resulted in the final layer with distances from the surface-water of 40-, 70-, and 100 meters.
