Title: IDXPTRNEAT - PLSS Township-RangeTiling Index for King County Raster Data
Feature Count: 0
Feature Type: Polygon
Abstract: A spatial tiling index designed for processing of file-based image and other raster (i.e., LiDAR elevation, landcover) data sets. A grid based on the Public Land Survey System (PLSS). It is different than the PLSS layer itself in that townships along the western edge of Puget Sound have been arbitrarily extended as full townships into the water. Polygons in portion of Pierce County and the eastern edge of King County have not been extended. The name of the spatial index is derived from the acronym (I)n(D)e(X) (P)olygons for (T)ownship-(R)ange, (NEAT) or idxptrneat. Tile label is the t(township number)r(range number)as in t24r02. The meridian zone identifiers, N for townships and R for range is inferred as this index is intended as a local index for ease of use by the majority of users of GIS data. Lowercase identifiers are used for consistency between Unix and Windows OS storage.
Purpose: This index or tile level is used for raster and vector clipping by township range and is simular to IDXPTRNEAT and is based the PLSS.
