Band Combinations:

Pan-sharpened Color: Color imagery is created using a pan-sharpening process that combines a high-resolution panchromatic image with the multispectral bands to create a 50-centimeter or 1-meter color product. GeoEye delivers 50-centimeter or 1-meter color imagery as either one file with three bands in true color (red, green, blue) or false color (near infrared, red, green); or four files of one band each (blue, green, red, near infrared) or one file with four bands.

Multispectral: 2 or 4 meter GSD imagery delivered as one file with three bands in true color (red, green, blue) or false color (near infrared, red, green); or four files of one band each (blue, green, red, near infrared) or one file with four bands.

Panchromatic: 50-centimeter or 1-meter resolution black and white imagery.

Bundle: Customers receive panchromatic and multispectral imagery. GeoEye-1 and IKONOS collect panchromatic and multispectral imagery simultaneously to ensure radiometric and temporal consistency.

Map Projections: Universal Transverse Mercator (UTM), Geographic (nominal ARC), Albers Conic Equal Area (ACEA), Lambert Conformal Conic (LCC), Transverse Mercator (TM) and State Plane projection (US only). Customers must supply desired parameters for ACEA, LCC, and TM projections.

Datums: Map-projected imagery products are available in a variety of datums such as: WGS849 (available worldwide), NAD83 and NAD2710.

Dynamic range adjustment (DRA): Enhances the visual interpretability of the image. If “DRA off” is selected, absolute radiometric accuracy and full dynamic range will be preserved for scientific applications.

Bits: Choice of 8 bit or 11-bit dynamic range.

Resampling: Cubic convolution (also called bi-cubic) is the default resampling method for panchromatic, multispectral, and color imagery. Nearest neighbor resampling is available by request but not recommended due to color anomalies that may result.

Image Format: GeoTIFF, NITF 2.0, NITF 2.1, or NITF 2.1 with NCD11.
Stereo imagery is available in NITF or TIFF format for epipolar imagery and NITF or GeoTIFF for map-projected imagery.

Media: DVD, CD, External Hard Drive, electronic delivery (FTP) or Signiant Service12.

Deliverables: Media with data (image and support files), License, Return Policy, Packaging list, Packaging.

Minimum Order Size: The minimum order size for new collections is 100 square kilometers. For archive products the minimum order size is 49 square kilometers. All imagery product orders must be a minimum of five kilometers wide in any direction.

Sun Angle: Solar elevation angle from ground to sun will exceed 15°. Solar azimuth is unrestricted. Collection geometry will avoid reflections of the sun from water bodies into the sensor. Our satellite orbits are sun synchronous; therefore, all imagery is collected at approximately 10:30 AM local solar time, however not necessarily at the same sun azimuth.

Clouds: Newly collected imagery from IKONOS and GeoEye-1 will have less than 15% cloud cover.13 GeoEye uses an automated process to calculate the percentage of cloud cover in each image collected. Additionally, customers can designate a single coordinate within the image that must be cloud free. The imagery delivered will be cloud-free in a 2 km by 2 km square centered on the customer’s designated coordinate.

Support Files & Metadata: All GeoEye products are shipped with a text metadata file that includes GeoEye contact information, order parameters (area of interest, spectral bands, and coordinate system), source image description (acquisition date, sun angles, and viewing geometry), and product file descriptions (file names, sizes, and coverage) and also a license file, shapefiles, TIFF, and JPEG thumbnail with world files. Shapefiles show order area of interest (AOI), delivery component layout, and source image footprints with acquisition geometry.
