Pennsylvania Spatial Data Access

Abstract:

Line shapefile depicting isolines created from the 1991-2020 precipitation raster dataset from the Spatial Climate Analysis Service, Oregon State University. This file should be used in conjunction with the 30 Year Precipitation dataset (1991-2020) for the Susquehanna River Basin. The attribute field for inches has been interpolated from the raster's VALUE field. The inch values should be viewed as approximate. The conversion is listed in the Entity Attribute Overview section of the document.

Purpose:

Dataset developed to fit the needs of the Susquehanna River Basin Commission.
