Skip straight to analysis with Maxar’s analysis-ready data (ARD). ARD is preprocessed time-series stacks of imagery that are aligned and produced at a set standard. Aligned image stacks from ARD provide increased usable content via localized metadata, more accurate feature extraction, faster processing, lower storage costs and homogenized ...

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...
Aug 12, 2022 · ARD is available for Maxar's GeoEye-1, WorldView-1, WorldView-2, WorldView-03 VNIR, and WorldView-4 satellite archives. ARD imagery includes three GeoTIFFs: a 3-band RGB image for visualization, a panchromatic image, and a 4 or 8-band multispectral image. A set of data masks in raster and vector formats accompanies each tile in an order ...
Dec 1, 2022 · The most common method for the delivery of ARD imagery is through Amazon S3 buckets. Delivery to an Amazon S3 bucket and prefix location requires the following: An S3 bucket policy must be applied. This policy gives Maxar ARD "write" permission to the bucket. Maxar's access to your bucket is limited to writing objects to your bucket.
Feb 24, 2021 · Maxar ARD handles orthorectification for you, and it offers our proprietary Bundle Block Adjustment (BBA) process to further refine the alignment of images within the ordered stack. BBA can be deployed on up to 50 images to create a deep temporal stack of aligned imagery.
Feb 2, 2021 · Maxar ARD provides consistent imagery, which speeds up the pixel-to-answer workflow and enables compute vision models to be deployed across geographies. Time Series Analysis. Maxar ARD is also optimized for the analysis of imagery over time because users can set their date range or desired stack depth and automatically align each imagery ...
