PNV Stream TMDL Temperature Modeling with Temperature Logger Locations (Potential Natural Vegetation) At DEQ, a PNV-style temperature TMDL analysis begins with an aerial photograph interpretation performed in the ArcGIS program. The procedure for making this interpretation is outlined below. Interpretations of existing shade levels are represented as 10% class intervals starting with shade class 0 (i.e., a shade value of 0), which represents shade levels ranging from 0 to 9.9%, and proceeding through shade class 90, representing shade levels from 90 to 100% (adapted from the CWE process, IDL, 2000). For example, a stream segment that is interpreted as having a shade level anywhere between 30 and 39.9% would be assigned a shade value of 30.
