Orthophotography data

Orthophotography data

Overview

The King County GIS Spatial Data Warehouse (KCGIS SDW) stores orthophotography and satellite imagery of multiple vintages, resolutions, and extents. Data is available in natural color, panchromatic (B&W), and multispectral formats, though not all versions are available for each dataset. Please refer to the descriptions below, and metadata where available, for more information about each dataset.

Due to the particular conditions contained in various licensing agreements, not all datasets are available for release to the public or agencies and cities outside of King County government. Data may be made available, with restrictions, to consultants and other parties operating under contract or other formal agreement with King County. Availability of data to other outside parties is included in the product listings on this page.

For data which King County is permitted to release, we can assist you in selecting the correct data and format for your needs, and in providing a cost-estimate for data preparation and media delivery. All imagery requests require submission of a Custom Data Request form in order for staff to properly estimate the effort needed to provide the data. The King County GIS Center can also assist you in contacting the original source or vendor for data that we are not permitted to redistribute.

Imagery datasets are available in various formats, resolutions and tiling schemes. Depending on your business needs, you may choose from the following.

  • Losslessly compressed 7500-foot tiles
  • Township-range tiles where the data is stored in a minimally-lossey image format
  • A seamless, project-wide mosaic dataset in which the imagery retains its native resolution

Quadrant file mosaics at the zone tiling level are also available. Plus, each dataset is stored as a single file mosaic in the SDW keyregion directory. These zone and keyregion file mosaics are more strongly compressed so lose some of their image quality, but are useful when easy access to the regional picture is important.

Beginning with the 2012 King County Ortho Project, a single, full-extent mosaic dataset has become the standard for publishing raster data to the SDW. Mosaic datasets are based on the 7500-foot tiles only, so new township, zone, and keyregion tiles are no longer be published to to the SDW, though custom mosaics can be requested.

Finally, the original, uncompressed TIFF data which corresponds to the losslessly compressed 7500-foot tiles is available only through a custom data request (and only for those imagery datasets that are licensed for distribution).

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 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: 2015 Western Washington Regional Orthophotography - RGB with 2 Foot Pixel Resolution

Abstract: This data set contains 2-foot, 3-band (RGB), 8-bit/band color orthophotography that covers a large and mostly contiguous urban area in the Puget Sound area of western Washington. An orthophotograph is an aerial photograph that is geometrically corrected using a 3D terrain surface so that the scale is uniform and the image lacks distortion, allowing for highly accurate horizontal measurement of most ground-level features. Over 1,006 square miles of digital aerial imagery suitable for 2 foot orthophotography was acquired by GeoTerra, Inc., in the spring of 2015 for the purpose of updating regional base mapping data. The regional project was a collaborative effort between multiple agencies primarily within the Puget Sound region. King County oversaw the project and acted as lead manager for the effort on behalf of 88 participants. The aerial imagery was acquired using multiple, large-format digital mapping cameras. Overlapping stereo imagery was aerially-triangulated into large block adjustments using new and existing surveyed control. Existing terrain data was updated, or in some areas newly acquired, and used for rectifying the aerial imagery into digital orthophoto mosaics. These ortho image files are in a 3000' x 3000' contiguous, non-overlapping tile structure and are available in uncompressed GeoTIFF format. Each are projected to NAD 83/91(HARN), Western Washington State Plane North Zone, US Feet.

Title: 2017 King County (Pictometry) Orthogonal Base Imagery - 3 inch (west) and 9 inch (east)

Abstract: Natural-color aerial imagery mosaic of King County and southwestern Snohomish County. The dataset consists of tiled orthogonal imagery produced from nadir images captured by Pictometry International Corp. from 2/17/2017 through 10/30/2017. Resolution is 3 inches per pixel (“Neighborhood” scale in Pictometry terminology) over urbanized, western King County, and 9 inches per pixel (“Community” scale) over rural, eastern King County. Also covered at the Neighborhood level are southwestern Snohomish County, the U.S. Highway 2 corridor in northeastern King County, and the Alpental area near Snoqualmie Pass. There are gaps in the completeness of the data. These gaps vary in size but are mainly distributed in the eastern portion of the county, with the far northeastern portion of the county (federal lands/wilderness areas) absent. The imagery in the mosaic is licensed to King County by Pictometry International Corp. for use by cities and other governmental entities only.
