Title: 1936 Aerial Photos for western King County panchromatic
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: 1993 Seattle
panchromatic
Abstract:
Acquired under leaf-off conditions,
this high-resolution black and white orthophotography has a 1-foot ground sample
distance (gsd) resolution. Coverage is the majority of the City of Seattle area.

Title: 1996 NIES natural color
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: 1998 WA Dept of Natural Resources (WADNR) panchromatic
Abstract:
Black and white leaf-on orthoimagery with
3-foot GSD. The data covers almost all of King County except for some
small sections in the eastern-most portion of the County. Some adjacent areas in
Snohomish County are also covered.

Title: 2000 DAIS natural color, color infrared
Abstract:
Low elevation, high aerial photography
collected in September for theVashon 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
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
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
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
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
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.
