Detail Data Ordering


Data Acquisition 		IKONOS was launched on September 24, 1999, and is owned and operated by Space Imaging, Inc. The data were first available January 1, 2000. Space Imaging, Inc. distributes IKONOS imagery under the product name CARTERRA.

Timing 		For areas of interest (AOI) less than 500 sq km, it takes 10 to 14 days to receive archived imagery; 60 days if the imagery must be collected. For all other image products, it can take up to 120 days.
[dollar sign icon]
Cost 		The prices of IKONOS imagery vary based on the accuracy of the product's georeferencing and any special data requests (i.e., different swath size, viewing angle, etc.). Price information can be found at the Space Imaging, Inc. Web site.
[cd icon]
Data Formats/Software Needed 		Choice of untiled GeoTIFF or uncompressed NITF (National Imagery Transmission Format) 2.0. NITF format is available to approved government customers and supports 3-band 8-bit data, or 4 separate bands at 8-bit or 11-bit. Resellers also offer IKONOS imagery in a variety of formats.

Projections

Supported Projections:
Choice of Universal Transverse Mercator, State Plane, Albers Conic Equal Area, Lambert Conformal Conic, or Transverse Mercator.

Supported Datums:
Choice of World Geodetic System of 1984 (WGS84), North American Datum of 1983 (NAD83), or North American Datum of 1927 (NAD27). WGS84 available worldwide. NAD83 available in North America only. NAD27 available in CONUS only.
