DENVER, Colorado, 26 October 2020 – TCarta Marine, a global provider of hydrospatial products, has announced development of new Machine Learning-based bathymetric mapping technologies – including creation of two software packages and commercial application of NASA’s ICESat-2 satellite – with funding from the National Science Foundation (NSF). Proposing signal detection and bathymetric error correction method for ICESat-2.
the surface of the Earth and from the atmosphere, including the inside of clouds, will be collected in a 1 meter diameter As TCarta begins the second year of its NSF Phase II grant, the company announced the release of two bathymetric software products developed through the program: In 2018, NSF awarded TCarta a Phase 1 grant to develop multi-method and integrate SDB technologies.

Flight Projects First ICESat-2 Global Data Released: Ice, Forests and More Help NASA Measure Trees with Your Smartphone To develop this capability ahead of the DESDynI and ICESat-2 missions, we propose to implement a system that enhances access to existing light detection and ranging (lidar) data sources hosted at NASA's National Snow and Ice Data Center Distributed Active Archive Center , Goddard Space Flight Center Land, Vegetation, and Ice Sensor Data Center, UNAVCO, and the San Diego … Recent Cyberinfrastructure developments, when integrated into existing Earth science data systems, can provide a framework for distributed data access and enhanced processing capability. The result was a 10-meter bathymetric map covering 130,000 square kilometers provided via the Esri Caribbean GeoPortal to organizations engaged in hurricane preparedness activities ahead of Hurricane Isaias.
The GLAS instrument aboard ICESat provided full-waveform lidar data for the earth’s forests from 2003 to 2010. Your email address will not be published.
During the commissioning phase of the mission, the ICESat was pla… It was designed and built at Goddard Space Flight Center, with the laser generation and detection systems provided by Fibertek. Satellite multispectral imagery has been widely used to estimate shallow water depths based on empirical models and physics-based models. DENVER, Colorado, 26 October 2020 – TCarta Marine, a global provider of hydrospatial products, has announced development of new Machine Learning-based bathymetric mapping technologies – including creation of two software packages and commercial application of NASA’s ICESat-2 satellite – with funding from the National Science Foundation (NSF). Use of a high rep-rate laser enables photon-counting detection, which in turn enables fast turn-around for data processing. GLAS was produced at Goddard Space Flight Center Training empirical models by ICESat-2 bathymetric points to estimate water depths. The laser altimeter measures the time required for a laser pulse of 5 nanosecond duration to complete the round trip from the instrument to the Earth's surface and back to the instrument. To develop this capability ahead of the DESDynI and ICESat-2 missions, we propose to implement a system that enhances access to existing light detection and ranging (lidar) data sources hosted at NASA's National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), Goddard Space Flight Center Land, Vegetation, and Ice Sensor (LVIS) Data Center, UNAVCO, and the San Diego Supercomputing Center. ICESat's primary objectives are to However, the in-situ water depth information is essential (as the priori) to use the empirical model in a specific area, which limits its application, especially for remote reefs. The commercial bathymetric mapping projects relate to oil spill management, oil & gas exploration and production, coastal infrastructure engineering, environmental monitoring, and geospatial intelligence (GEOINT) activities. As ICESat orbited, GLAS produced a series of approximately 70 m diameter laser spots that were separated by nearly 170 m along the spacecraft's ground track. Satellite lidar data from ICEsat, high altitude airborne lidar data from LVIS, and low altitude airborne lidar from the UNAVCO and SDSC's extensive Earthscope catalog will be incorporated into the OpenTopography Portal. The main objective of the GLAS instrument was to measure ice sheet elevations and changes in elevation through time. “The NSF grant has brought value to the bathymetric mapping arena in many ways,” said TCarta President Kyle Goodrich.

The sole instrument on ICESat-2 is the Advanced Topographic Laser Altimeter System (ATLAS), a space-based lidar. This site uses Akismet to reduce spam.
