Title: 1936 Aerial Photos for western King County panchromatic imagery

Abstract: Acquired under leaf-on conditions. 1936 aerial imagery for western King County was scanned from 3 foot by 3 foot prints. The source is the original hardboard-mounted aerial prints. The original 0.5 foot pixel resolution was resampled to 1 foot pixel. The purpose of the imagery is historical comparison and Archiving original documents.

Title: 1996 NIES natural color imagery

Abstract: Acquired in June and July by the NIES Mapping Group of Bellevue (now Triathlon, Inc.) as part of their Digital Orthophotos of the Puget Sound Region Project.  GSD is 1 meter and data is 3-band, 8-bit data. Acquisition altitude was 15,000 feet above mean ground, providing photography at a nominal scale of 1:30,000. USGS Digital Elevation Model (DEM) control was used for orthorectification resulting in 1:20000 map scale accuracy. The King County Spatial Data Warehouse (KCGIS SDW) contains the portion covering most of western King County and portions of southwestern Snohomish County.

Title: 2000 DAIS natural color, color infrared imagery

Abstract: Low elevation, high aerial photography collected in September for the Vashon and Maury Islands portions of King County. The data has a gsd of 0.5 meters. The data was acquired as 4-band, 16-bit multispectral imagery, with 3-band, 8 bit natural color and color infrared versions created for general use.

Title: 2000 Emerge natural color, color infrared imagery

Abstract: Low elevation, high-resolution aerial photography collected in late spring to early fall for western King County and southwestern Snohomish County. Data was acquired as 3-band color infrared imagery at 2-foot gsd. Band ratios were used to create a natural color derivative from the red, green and infrared bands (blue band not acquired).

Title: 2000 Ikonos natural color imagery

Abstract: Although acquired from a satellite platform, this data appears as orthophotography though at medium resolution and with less horizontal accuracy as most orthophotography. Collected during August through October for eastern King County, this imagery combines the three visible color bands into a natural color product. The protracted acquisition campaign collected data under varying conditions that resulted in some illumination and tonal variation.

Title: 2000 Space Imaging natural color composite imagery

Abstract: This composite consists of the same imagery comprising the separate DAIS, Emerge and Ikonos datasets. This version combines all three into a county-wide 4-foot resolution dataset providing seamless year 2000 coverage, which is difficult to display with the individual datasets. Includes the improved color-balanced Ikonos data and edited shoreline tiles. Tonal differences between datasets are still apparent due to the original specifications of the individual datasets. The original datasets are still available where the higher, original pixel resolution is required.

Title: 2002 King County natural color imagery

Abstract: Data is 1-foot pixel resolution, natural color imagery orthorectified to a digital terrain model (DTM) created from the the lidar-based ground elevation model. As with all other imagery in the Spatial Data Warehouse, this imagery is stored at all tiling levels. Users can access the main township-range tiles in MrSid format. Larger zone and keyregion mosaics are also available in MrSid format, though in a more highly-compressed, reduced-resolution format. Coverage area includes southwestern portion of Snohomish County (WRIA 8) coincident with the lidar acquisition area. The 2002 King County natural color dataset provides full county coverage whereas the USGS 2002 imagery covers only the western portion of King County. Besides positional accuracy the datasets also vary in tonal quality and sun/shadow angle. These factors should also be considered in determining the best imagery for your business or mapping requirements.

Title: 2002 USGS natural color imagery

Abstract: Western King County only imagery extracted from Seattle-Tacoma high-resolution orthophotography project. Imagery acquired in June at 1/3-meter gsd. Data reprojected, retiled and resampled to 1 foot GSD. This imagery has been rectified to lower-resolution digital elevation models as compared to the 2002 King County natural color imagery which has been rectified to lidar-based elevation data.
