Sub-meter Satellite-Derived Bathymetry Now Commercially Available

A world first from EOMAP and Satrec Initiative.

The teams of EOMAP and Satrec Initiative have launched the world’s first commercial, sub-meter bathymetry product based on satellite imagery.

“We’ve successfully processed KOMPSAT-3 derived bathymetry for different sites with varying recording conditions. The product quality in terms of spatial resolution, accuracy and signal-to-noise-ratio was a positive surprise to our team. We’re therefore proud to announce that commercial satellite-derived bathymetry (SDB) has now reached sub-meter horizontal resolution, specifically in this case 70cm spatial resolution” explained Dr. Thomas Heege, CEO of EOMAP.

KOMPSAT-3 is a recently launched multispectral satellite, which has the latest state of the art technology to measure the Earth’s surface at very high resolution. It captures more than 300,000 sq km of the Earth surface every day, approximately the size of Ireland and Britain combined.

MoonGyu Kim, of Satrec Initiative commented “We are very pleased with the high quality of bathymetry products that EOMAP derived from KOMPSAT-3 imagery. I believe the new products developed by EOMAP will be a very cost effective and valuable way of obtaining bathymetry data.”

The EOMAP team processed KOMPSAT-3 data and produced bathymetry for study sites at which they had previously derived bathymetry products using other satellite imagery, and for which validation data was available. This enabled both a comparison with other bathymetry products as well as an objective evaluation of the results.

“Our SDB service will strongly benefit from the KOMPSAT-3 derived image data. They can now be used in synergy with other high resolution data in our algorithm workflow. EOMAP is now able to offer low cost and rapid bathymetric data from 30 to 5 to 2 to 0.7m resolution, providing bathymetry layers for every purpose,” said Abhay Mittal, CMO EOMAP.

“Together with the attractive costs of the KOMPSAT-3 imagery we’re confident in providing industry-leading, very high resolution services to our clients and we invite everyone interested to visit us at our booth R110 at the Oceanography International conference, which is being held next week in London“, added Dr. Heege.

EOMAP is a world leader in aquatic remote sensing services, notably using optical sensors to derive bathymetry, seafloor and water quality products. EOMAP has a worldwide presence, including in Germany, Singapore, U.S. and Australia.

About KOMPSAT- 3
KOMPSAT-3 is the first sub-meter optical satellite developed and operated by the Korea Aerospace Research Institute (KARI). Orbiting our planet at 685 kilometers (km), KOMPSAT-3 collects 70-centimeter (cm) panchromatic and 2.8-meter (m) 4-band multispectral (blue, green, red and near-infrared/NIR) imagery.
