2000 Space Imaging natural color orthoimagery - merged DAIS, Emerge and Ikonos for full county coverage

Learn more by reading the GIS FAQ 🗺

Summary

This image dataset comprises 373 individual image tiles stored in TIFF format that can be displayed as a single seamless mosaic.

The images were converted from original 'False Color" near-infrared format to a natural color derivative.

The imagery, within the horizontal accuracy and resolution limitations, serves as digital backdrop imagery for GIS 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 lat spring to early fall 2000 for western King County and southwestern Snohomish County.

The data has a pixel size of 2 feet and is displayed in a natural color derivative for visual analysis

Supplemental Information	The images were created by converting original 'False Color' near-infrared TIFF images to a natural color derivative. It is considered a natural color derivative rather than a true natural color product as the original data is limited to 3-bands only, omitting the blue band. An algorithm was applied to the original data to closely mimic a natural color image. The images may be accessed as individual TIFF file by tile, as a pseudo-mosaic by using the associated image catalog dbase (emerge_nat.dbf) file, where supported, or as a single MrSid mosaic (emerge_nat.sid), where supported. Detailed photodate information is not available. A general overview at the township-level for data capture dates can interpolated from www. https://www5.kingcounty.gov/sdc/raster/ortho/images/ortho2000emergegeneralflightdate.jpg
