The Apollo Mapping team is pleased to announce that we have added another high-resolution satellite to our product selection, KOMPSAT-3, and sales of this data will start immediately!
If you are not familiar with KOMPSAT-3, here is a summary of the key satellite specifications:
A 70-cm natural color sample image collected by KOMPSAT-3 on August 24, 2013 over Bagram Airfield. This imagery has been photo enhanced by Apollo Mapping. Additional samples of color 70-cm KOMPSAT-3 imagery can be found here.- Launch Date: May 17, 2012, 16:39 UTC

Having worked with sample images for the past several weeks, we are extremely impressed with the crispness of KOMPSAT-3 data and its color reproduction. We feel that KOMPSAT-3 separates itself from other high-resolution satellites in two key ways:
(1) 14-bit depth which is important for spectral analysis. With 14-bit depth data, KOMPSAT-3 has a maximum digital number (or pixel value) range of 16,384 units. Compared with the maximum digital number range of 4,096 for Pléiades 1 and then 2,048 for the other high-resolution satellites in orbit now, this is a significant advantage for you remote-sensing academic and professionals out there.
(2) A 1:30 PM local collection time. All other high-resolution satellites collect imagery during the mid-morning, so an afternoon collection time can be an advantage in persistently cloudy areas like tropical islands. This is also an advantage for vegetation analysis as chlorophyll concentrations change though out the day; so coupling KOMPSAT-3 with imagery collected during the morning, can give researchers a more complete picture of plant health.
If you are interested in pricing, coverage and/or have any additional questions about KOMPSAT-3 data, please contact the Apollo Mapping sales team at sales@apollomapping.com or (303) 993-3863.
