Commercial Datasets

NEW! EarthDEM data is now available in SDX, for all U.S. federal employees and contractors, as well as federally-funded researchers for scientific purposes.

NASA's Commercial Smallsat Data Acquisition (CSDA) Program evaluates and procures data from commercial vendors that advance NASA’s Earth science research and applications activities.

Currently, all CSDA data acquired from Planet, Maxar (formerly DigitalGlobe), and Spire Global are available to government users. An initial release of a subset of the EarthDEM products, developed by the Polar Geospatial Center, is also available. Data from the Teledyne Brown Engineering DLR Earth Sensing Imaging Spectrometer (DESIS) also are available through a separate collaboration with the International Space Station (ISS). See the table below to learn how to access vendor-specific data. All data products are available through CSDA at no cost to authorized researchers and are subject to scientific use licenses.

The commercial data currently distributed by NASA are available under different scientific use licenses and various access portals. Please see table below for data access portals and vendor-specific end user license agreement (EULA) information. Check back for updates on new data acquisitions.

Spire designs, builds, and operates a growing constellation of over 120 3U Low Earth Multi-Use Receiver (LEMUR) satellites tasked with collecting Radio Frequency (RF) signals from low Earth orbit. The company offers a suite of commercial RF sensing products, including a catalog of atmosphere, ionosphere, and weather data services derived from Global Navigation Satellite System (GNSS) signals collection.

The Spire-designed STRATOS payload collects these GNSS signals from which Spire can derive useful Earth Observation data types for climate and space weather research, among other applications. To support their mission, the company owns and operates over 30 ground stations and a robust data pipeline for quickly and securely moving data from orbit to cloud.

Signal-to-Noise ratio (albedo 0.3 @ 550 nm)	195 (w/o binning) 386 (4 binning) (based on on-ground calibration)
Dark/Read noise (electrons)	30-60e- (global shutter) 15-30e- (rolling shutter)
Quantum scale equivalent (e-/DN)	0.04 e-/DN
Max frame rate	235Hz (@235 spectral lines, rolling shutter) 117Hz (@235 spectral lines, global shutter)
Solar zenith angle restrictions (for L2A level processing)	> 55° produces reduced quality L2A product > 65° produces low quality L2A product > 70° not processable to L2A

¹ with respect to global reference Landsat ETM+ PAN with GSD 14 m.
