Detailed Description

ak_precip is a polygon coverage created from a 1:2000000 scale map showing lines of equal annual precipitation in Alaska. The precipitation map was prepared in 1994 as part of a flood frequency study of the streams and rivers of Alaska and was digitized into a GIS format. Precipitation values for polygons were set to equal the average value of their bounding lines of equal annual precipitation.
