Abstract:
2013 King County natural color orthogonal magery acquired by Pictometry for internal business and agency use only. Pixel resolution is 0.75 foot GSD in rural (east) King County and 0.33 foot GSD in urbanized (west) King County. Higher resolution data includes portion of southwestern Snohomish County, the Highway 2 corridor in northeast King County and the Apenal area near Snoqualmie Pass. The 0.75 foot data is also known as Neighborhood-level imagery whereas the 0.33 foot data is known as Community-level imagery.
Purpose:
Color imagery mosaic for King County and portions of adjoining counties. This ortho-mosaic is a visualization product and is not intended or valid for authoritative or definitive use. Portion of larger Pictometry package that contains their proprietary oblique and orthogonal view imagery for the same project area.
Supplemental_Information:
To correctly determine the acquistion date and time for an area you need to use the spatial indexes - OBLIQUE_IMAGE13_AREA and ORTHO_IMAGE13_AREA.

Logical_Consistency_Report:
7500-foot tiles are created from a mosaic of Pictometry's ortho tiles. Some tiles will be a combination of 0.75 foot and 0.33 foot imagery. Imagery was captured over a three months in a block-type pattern, with infill areas. Because this imagery is not true 'orthophoto' imagery there are some tonal variations across many of the tiles due to variations in lighting conditions. The mosaic tiles also show numerous examples of mis-alignment along seamlines with offsets and other artifacts that indicate the images of different vintage were mosaicked.
Completeness_Report:
Except for a small 'hole' in the water around Vashon Island there is complete imagery for the project area.

Process_Description:
Pictometry provided their orthogonal tiles in two folders: 4 inch and 9 inch, both in JPG format. The 4-inch tiles are 2700 feet on edge and the 9 inch tiles are 5400 feet on edge. A python routine was created to mosaic the tiles into new 7500x7500-foot tiles in MrSid format. The compression was lossless. 7500 tiles comprised of all 4-inch tiles were named 'grid-cell'_13n033.sid, while those in the 9-inch area were named 'grid-cell'_13n075.sid. When a 7500 grid cell spanned both 4-inch and 9-inch input tiles, the tile was assinged the higher resolution suffix - 033, These tiles were published to the King County GIS production server. A esri Mosaic Dataset was created
