NASA LCLUC

  Dear LCLUCers, friends of LCLUC, international colleagues,   As you see, my wishes a year ago for the virus-free 2021 were not fulfilled. The second year has passed with restrictions varying from stricter to softer and back to stricter, the new variants coming in waves. Now I’d be cautious to predict what will happen next year although a year ago vaccinations were just becoming available, and currently most people I know are vaccinated. We all adjusted to the changes in our personal life and work mode, became experts in virtual meetings, giving up international travel, but started some socializing and participating in limited holiday celebrations. In keeping with the LCLUC tradition, I will herein summarize achievements of the second strange year – 2021 - list our plans and convey my best wishes to the whole LCLUC family and our friends around the world. So, here we go. Solicitations. LCLUC-19 and -2021 selections brought many Early Career Scientists and diversity in ...

Dear LCLUCers, friends of LCLUC, international colleagues, Greetings for the New Year 2020. I would like to convey my best wishes to the whole LCLUC family and our friends around the world.  During the past 5 years, the geographic focus of the program has been on Asia with socio-economic aspects of land use as an integral part of the program. However, the most recent solicitation has opened the geographic interests of the program to other regions. Our program, along with many colleagues over the world, is investing in developing multi-source methods in studying LCLUC using all available mid-resolution resources, Landsat and Sentinel-1,2 being the primary assets as they freely and easily available. I appreciate contributions from each and every one of you in keeping the LCLUC a global outreach, vibrant program at NASA’s Earth Science. This past year the program has had another aspect that may push the envelope further in our monitoring capabilities. Several of the o...

Dear LCLUCers, friends of LCLUC, international colleagues,   Greetings for the New Year 2019. In keeping with the LCLUC tradition, I would like to summarize our past year achievements, mention some future plans and convey my best wishes to the whole LCLUC family and our friends around the world. The geographic focus on Asia with socio-economic aspects of land use has remained an integral part of the program until recently. However, the new solicitation is expanding the geographic interests of the program as you will see below. Along with the continued observations from the LCLUC workhorse mission – the Landsat program –, we have experienced a tremendous increase in the number of observations at landscape scale owing to our partner agency ESA’s Sentinel program. Our program, along with many colleagues over the world, is investing in developing multi-source methods in studying LCLUC. I appreciate contributions from each and every one of you in keeping the LCLUC a global ...

Liza Goldberg, 10th Grade Intern at NASA Goddard Biospheric Sciences Lab Project Summary: In order to address the need for a unified risk management system for mangrove loss, the Electronic Coastal Monitoring and Assessment Program (EcoMap) was developed to identify the locations and drivers of mangrove degradation worldwide, as well as project future areas of stress or loss. Time series and disturbance metrics were used in generating both individual losses driver maps and total vulnerability maps for mangroves on a global scale, and country-based vulnerability statistics were calculated for all mangrove-holding nations to inform the United Nations Sustainable Development Goals. In the future, we aim to bring EcoMap to coastal communities and stakeholders worldwide, in order to create a network of global mangrove monitoring and informed decision-making efforts.

**Yellow indicates newly flooded areas overlaid on Google Earth basemap. Typhoon Doksuri inflicted significant flooding across extensive regions in Vietnam and other countries in September 2017. An innovative satellite remote sensing method* has been developed and implemented for use with Sentinel synthetic aperture radar (SAR) satellite data at a resolution of 10 meters to identify, map, and monitor inundation including pre-existing/pre-flood water bodies (e.g., lakes, reservoirs, rivers, coastal ocean, etc.) and newly flooded areas after the typhoon made landfall.  Because Sentinel SAR operates at C-band microwave frequency, it can be used for flood mapping regardless of could cover conditions typically associated with storms, and thus can provide immediate results without the need to wait for the clouds to clear out. Attached is a high-resolution 4K-UHD flood map of a region around Hà Tĩnh (north central coast of Vietnam) showing flood inundated areas (in ye...
