Meidum Resolution satellite imagery - UAE RapidEye

2014 5m RapidEye ortho mosaic of the United Arab Emirates. LAND INFO offers multiple imagery and mapping solutions for affordable, large-area coverage.

Medium-resolution imagery is ideal for covering large areas – countries, continents and in the case of Landsat the entire globe!  While there isn’t a text-book definition of “medium-res” satellite imagery, for practical purposes it typically means resolution less than 1m. Medium-res satellite imagery was traditionally offered on a scene basis, however newer medium-res satellites such as RapidEye and SPOT 6/7 now support custom AOIs (Areas of Interest) with per km2 pricing. 

With the exception of WorldView-2/WorldView-3, medium-res satellites typically offer additional multi-spectral bands, which make them ideal for image analysis/classification. Their larger collection swath widths allow them to collect large areas in a shorter amount of time, giving better temporal selection. With commercial medium-res satellites such as RapidEye and SPOT 6/7 imagery can be ordered as a new tasking collection or from archive (if the needed date/image type is in archive with acceptable parameters including cloud-cover), free to low-cost government medium-res satellite imagery is only available from archive (custom new collects aren’t supported.)  Off-shelf high-res products such as DigitalGlobe’s Basemap +Vivid are also cost-effective solutions for large area coverage. Contact LAND INFO for additional details.

The table below lists the principal medium-resolution satellite imagery options; LAND INFO is an authorized distributor of both leading commercial medium-res satellite imagery providers: Airbus SPOT Image and Planet Labs (formerly BlackBridge) RapidEye. We also work extensively with ASTER and Landsat 8 and will work with niche satellites such as ALOS, CartoSat, CBERS, DEIMOS-1, DMC, Formosat, Landsat 1, Landsat 2, Landsat 3, Landsat 4, Landsat 5, Landsat 7, Planet Labs, ResourceSAT, Sentinel-2A/2B, SPOT 1, SPOT 2, SPOT 3 & SPOT 4 and TripleSat as needed, for example date-specific coverage.

Please contact us with your requirements, our highly trained and specialized staff is happy to make a data recommendation that will help ensure the success of your project.

  • 1 at nadir
  • 2 Horizontal accuracy CE90 (Circular Error 90%) without GCPs (except RapidEye), excluding terrain and off-nadir effects
  • 3 2.5 meters from 2 x 5-meter scenes
  • 4 RapidEye is the only imagery listed where GCPs (but not a DEM) are used with the Basic (1B) imagery, therefore accuracy is
       higher in areas where higher accuracy GCPs are available, such as USA
  • 5 35m CE90 without GCPs within a 30 degree viewing angle cone; 10m CE90 for Ortho products where Reference3D is available
  • 6 ASTER SWIR data after April, 2008 is not useable
  • 7 Landsat 8 Thermal imagery is acquired at 100m resolution but resampled to 30m for delivery
  • 8 Characteristics refer to the optical PRISM and AVNIR-2 sensors not the radar PALSAR
