Maxar satellites are "agile" and can sweep their sensors over the earth to capture long strips of imagery. For consistency, the sensor usually acquires an image in a roughly north-south orientation. This means that Maxar acquisitions can vary in shape and size. Below shows an acquisition that is about 16 kilometers wide by 52 kilometers long. The l...
When ARD imagery is ordered, three cloud-optimized GeoTIFFs (COGs), a set of data masks, and the metadata for these images are delivered.
ARD datasets are currently produced from data collected by the following satellites from the Maxar constellation: GeoEye-1: View or download the GeoEye-1 datasheet WorldView-1: View or download the WorldView-1 datasheet WorldView-2: View or download the WorldView-2 datasheet WorldView-3 (VNIR): View or download the WorldView-3 datasheet WorldView-4...
Maxar ARD is available for areas within the boundaries of Maxar's Digital Elevation Model (DEM). ARD is not available in the Arctic, Greenland, or Antarctica. There is 100% DEM coverage between 60N and 56S latitude. This image shows the geographic extent of ARD availability. Areas without grid cells are unavailable.
Imagery from ARD is organized on a globally discrete grid system. Locating images on a common grid system simplifies time-series analysis. It also serves as a structure to organize the files. A recursive quadkey structure is used to define the grid structure. Simply put, quadkey structures involve dividing a square space in half in each direction t...
