2000 DAIS Natural Color 8-bit Aerial Photography
Learn more by reading the GIS FAQ 🗺
Summary
This image dataset comprises 25 individual image tiles stored in TIFF format that can be displayed as a single seamless mosaic.
The raw imagery was converted to natural color version.The imagery, within the horizontal accuracy and resolution limitations, serves as digital backdrop imagery for GIS analysis and cartographic display.
In particular, the absolute and relative horizontal accuracy should be carefully considered when either determining coordinate positions or when applying the data relative to other spatial datasets.
Description
Low elevation, high resolution (i.e., small ground sample distance (GSD)) aerial photography collected in September, 2000 for Vashon and Maury Islands, portions of King County that reside in Puget Sound, approximately 5 miles west of the city of Seattle.
The data has a pixel size of 0.5 meters and is displayed in natural color for visual analysis.

| Supplemental Information |
The images were converted from original 4-band, near infrared, 16-bit format to 3-band, natural color, 8-bit format. The reduction in dynamic range of the data from 16 to 8 bit allows the imagery to be viewed in most image viewing and GIS software. This is a true natural color image as the images were created by dropping the near infrared band and combining the remaining blue, red and green bands. The images can be accessed as individual TIFFs tile by tile, as a pseudo-mosaic by using the associated image catalog dbase file (dais_nat.dbf), where supported, or a single MrSid mosaic (dais_nat.sid), where supported. |
