The landcover interpretation was created to provide an up-to-date landcover interpretation for the project area. The classification scheme was devised considering various county-wide mandates affecting multiple departments.
Primary drivers for the classification schema and effort are implementation of Endangered Species Act mandates, buildable lands definition and sensitive areas mitigation.

Data sources used in this process:
The 2001 image was acquired from the Snohomish County Public Works Department. It is an NALP product of a LANDSAT 7 ETM+ image with a systematic level processing (meaning satellite ephemeris information was the source of georectification). This was found to be a geoprecision level of approximately 3 pixels alignment to the 7 July 2000 orthorectified image purchased for this project. The 1994 image is a Map-oriented processing level Landsat 5 Thematic Mapper Image at 25 meter resolution (five pixels for 1994). Appropriate Process steps to orthorectify the 1994 and 2001 were done by Marshall and Associates, Inc. Center to center pixel spacing is 25 meters with an average horizontal accuracy of 22.8 meters.
There are no gaps in the data. All cells were classified as one of the values found in the entity section.
all cell values in the range of 0-1. A 0 value represents no change and a 1 value represents change from 1994-2001
