Color satellite photos in four bands (GeoEye-1)

GeoEye-1 Level 1B Multispectral 4-Band Satellite Imagery
land NASA CSDA Level 1B active GeoTIFFNITF21NCDRD
In plain English

What it measures. High-resolution color satellite photos of land, captured in four channels of light: blue, green, red, and near-infrared (a band just beyond what our eyes can see). Each pixel covers a patch under two meters across, sharp enough to make out individual buildings and roads.

How it's made. Taken by the commercial GeoEye-1 satellite and delivered as a sensor-corrected but raw, un-projected product (the early processing stage, before being fitted to a map grid).

How & where you'd use it. Useful wherever detailed, frequent imagery is needed, such as mapping, disaster response, and land monitoring. Access is restricted under a government license, so investigators must be approved before they can use it.

Official description

The GeoEye-1 Level 1B Multispectral 4-Band L1B Satellite Imagery collection contains satellite imagery acquired from Vantor, Inc. (formerly known as Maxar Technologies) by the Commercial Satellite Data Acquisition (CSDA) Program. Imagery is collected by the GeoEye-1 satellite using the GeoEye-1 Imaging System across the global land surface from September 2008 to the present. This satellite imagery is in the visible and near-infrared waveband range with data in the blue, green, red, and near-infrared wavelengths. The imagery has a spatial resolution of 1.84m at nadir (1.65m before summer 2013) and has a temporal resolution of approximately 3 days. The data are provided in National Imagery Transmission Format (NITF) and GeoTIFF formats. This level 1B data is sensor corrected and is an un-projected (raw) product. The data potentially serve a wide variety of applications that require high resolution imagery. Data access is restricted based on a National Geospatial-Intelligence Agency (NGA) license, and investigators must be approved by the CSDA Program.
