如何从卫星获得浅水浴序测量

TCarta海洋,海洋地理专业供应商ducts, is commercializing a new technique to derive highly accurate shallow-water bathymetry measurements from NASA’s ICESat-2 satellite data. The new methodology is being developed with funding from the National Science Foundation (NSF). In 2018, NSF awarded the company a Phase 1 Small Business Innovation Research (SBIR) grant to commercialize new satellite-derived bathymetric (SDB) measurement technologies. Referred to as Project Trident, the research focused on leveraging Artificial Intelligence (AI) – machine learning and computer vision – to determine shallow-water seafloor depth in variable water conditions.

“As participants in NASA’s Applied Users Program, we incorporated laser data from ICESat-2 as a validation tool for the enhanced SDB technologies under development,” said TCarta President Kyle Goodrich. “The results were so impressive we plan to introduce a stand-alone ICESat-2 bathymetric data extraction tool as one of several commercial products from our NSF work.”
NSF awarded TCarta a $750,000 Phase 2 grant in late 2019 to continue Project Trident for an additional two years. Phase 2 will incorporate the new ICESat-2 research into the project’s original objective of enhancing existing SDB technologies with AI capabilities to measure seafloor depths in diverse water conditions.
“The breakthroughs we made with NSF funding will enable us to apply SDB technology in geographic areas and water conditions not previously possible,” said Goodrich. “The results will have commercial impacts on marine operations related to oil and gas exploration and production, coastal infrastructure engineering, environmental monitoring, and geospatial intelligence (GEOINT) activities.”
高分辨率光学卫星图像
TCARTA在2014年开创了高分辨率光学卫星图像在2014年进行海底深度测量的应用,专有技术的商业化。然而,这种SDB技术仅限于浅沿海地区的相对平静和清晰的水域。2018年,TCARTA与加利福尼亚州圣卡洛斯Jomegak合作(我们)and DigitalGlobe of Maxar Technologies (DigitalGlobe) of Westminster, Colorado(我们)on Project Trident.
The Project Trident team added ICESat-2 space-based laser data to the project shortly after the small satellite’s launch in 2018. Developed by NASA and the University of Texas, ICESat-2 (Ice, Cloud & land Elevation Satellite) was designed primarily for polar ice elevation and tree canopy measurements, but the green laser altimeter on board has proved remarkably accurate at gauging seafloor depths down to 100 feet below the surface.
