Summary
Provide a project-wide (King County and southwest Snohomish county) generalized interpretation of impervious and impacted surface current to 2015 for those areas completed.
By exclusion, null value areas imply vegetated or water.
Can to be used, within limitations of accuracy at suitable scales, to determine the distribution of these types of surfaces across the project area and to make first-order areal calculations.
Description
Year 2015 Impervious/Impacted Surface data, based primarily on spectral vegetative index applied to 2015 color infrared aerial orthoimagery.
Updated with ancillary vector sources.
Significant manual edits to remove commission error were applied.
