Have you considered DEIMOS-1 as a replacement for the failing Landsat 7 mission? If not, it is worth giving it a look; and if so, give it a second one!

Our mapping and research-focused clients have found DEIMOS-1 to be superior to Landsat 7 in multiple ways:

  • It offers better multispectral resolution at 22-meters.
  • DEIMOS-1 can be tasked to time new collections of imagery with field research.
  • The archive is robust with a low minimum order price.
  • There are no scan line failures.
  • The price for DEIMOS-1 is well below $1 per square kilometer.

The production options for DEIMOS-1 are similar to other commercial medium-resolution sensors. Here is the advice we can offer when considering DEIMOS-1 for your next project:

  1. Processing Level
    1. L0R – this is product has been radiometrically corrected but has not been geometrically corrected; it is meant for user who wish to orthorectify DEIMOS-1 data on their own.
    2. L1T – this product has been manually orthorectified (10-meter RMS) to a base layer Landsat ETM+ reference image; this is the default processing level.
  2. Radiometric Calibration
    1. All gain and bias coefficients needed to convert raw digital numbers to radiance are included in associated metadata files.
  3. Delivery Format
    1. All data products are delivered as GeoTIFFs. A TFW file is also delivered with geometrically corrected products.
    2. Metadata information can be found in the .dim file. Much of this information is also summarized in the .htm file which is easier to read using a web browser.
