Detailed Description

Social scientists at the U.S. Geological Survey (USGS) Fort Collins Science Center – in collaboration with the USGS National Land Imaging Program – conduct Earth observation user case studies using qualitative research methods. Using standard scientific methods, they are better able to understand the variety of Earth observation users, including how they use and value Earth observation data. This video guides you through a series of Earth observation users. Women have been key leaders in Landsat’s long legacy of technological innovation, Earth’s long term monitoring, and making a difference through applied science. The amazing thing about Landsat’s long-term catalog and open access data policy is that women from around the world and of all ages can make discoveries and contributions using cyber infrastructure and cloud data-processing platforms, whether at a local or global scale. Through its free and open data policy, Landsat Collection Products (Level 2 C1/C2), Landsat Science Products (Dynamic Surface Water Extent, Fractional Snow Covered Area, Burned Area, Provisional Actual Evapotranspiration) the USGS/NASA Landsat program helps break down barriers to entry for many Ladies of Landsat who were previously excluded from the field of remote sensing. With Analysis Ready Data at their fingertips, Ladies of Landsat no longer need to search or invest in heavy processing software and equipment and can educate themselves through an online community of learners and teachers. Ladies of Landsat demonstrate the power of the pixel and Landsat’s diverse applications in their work and how Landsat makes their work possible. Representation matters; young ladies going through their K-12 education (and beyond!) crave the ability to see women in positions of scientific power, able to make a difference with their work. Landsat is a joint USGS/NASA Program that provides the longest continuous space-based record of Earth’s land surface. Every day, Landsat satellites provide essential information to help land managers and policy makers make decisions about resources and the environment.

Hi. My name is Dr. Kate Fickas. I'm from Santa Barbara, California. I use Landsat, unoccupied aerial systems, and gridded climate data to study things like wetlands and water quality so that natural resource managers can make informed decisions about conservation, ecosystems, and the landscape.

Hello. My name's Morgan Crowley. I'm located in Ottawa, Canada. I use Landsat to map and monitor wildfires in extreme fire seasons, and, in particular, I combine it with other satellite sources to track fires as they're growing.

I am Txomin Hermosilla, Research Scientist at the Canadian Forest Service, and I use time-series Landsat data to map forest dynamics.

Hi. My name is Alexandra Runge, and I'm located in Potsdam, Germany. I use Landsat to map and monitor the annual dynamics of permafrost thaw disturbances, which occur in northern high latitudes, such as Siberia, Canada, and Alaska.

My name is Dr. Andrew Davidson. I am the Earth observation operations manager for Agriculture and AgriFood Canada based in Ottawa, Ontario, Canada. We use Landsat data to map every crop in every field in Canada on an annual basis.

I'm Dawn Wright from Redlands, California, and I promote the use of web apps that draw on Landsat's different bands to better explore the planet's geology, vegetation, and coastal communities, including changes over time.

Hello. I'm Gizem Şenel. I'm located in Istanbul, Turkey. I use Landsat data to monitor and map water bodies, specific lakes and coastal lagoons to assess the artificial impacts on coastal systems.

Hi. My name is Dr. Flávia Mendes, and I'm located in Munich, Germany. I use Landsat image to analyze the impact of forest fragmentation and edge effect on forest carbon in the region of Cerrado and Amazon biome.

Just like many, many, many of us, my first introduction to satellite mapping was through Landsat. To date, it's about 10 years, and I still use Landsat to study the largest mangrove forest in the world, the Sundarbans.

Hi. I'm Dr. Eleanor Stokes. I'm a senior scientist at the Earth from Space Institute based out of Columbia, Maryland. I primarily use the VIIRS day/night band and the black marble product suite, but also combine that with Landsat and other daytime imagery to understand how urban areas are changing and how their land use and their land patterns are impacting the critical functions of the planet.

Hi. My name is Aurélie Shapiro. I'm based in Berlin, Germany. I work for the Food and Agriculture Organization of the United Nations, and I currently work with Landsat on mapping and monitoring forest, notably, deforestation and degradation in the Congo basin.

Hi. I'm Leander Campbell from Agriculture Canada in Ottawa. I use Landsat in combination with Sentinel and radar sat information to create crop maps of all of the agriculture that's grown across Canada every year.

Hi. I'm Keiko Nomura. I just moved from Edinburgh, Scotland, UK, to San Francisco, California. I use Landsat for land cover classification, vegetation, or drought monitoring, including wildfire risk assessment and biomass estimation.

Hi. My name is Andréa Nicolau. I'm based in Rio de Janeiro, Brazil. I use Landsat together with other sensors to map disturbances in tropical forests, such as the Amazon rainforest.

Hi. I'm Jen Hird, and I'm located in Calgary, Canada. I use Landsat to look at forest recovery after human disturbance, like harvest or mining, so that we can better understand broadscale patterns and the cumulative effects of these disturbances.

I'm Dr. Tanya Harrison. I live in Washington, D.C., and I use Landsat data to help understand landscape change in the Arctic and the Antarctic, especially as it relates to climate change.

Hi. I'm Prudencia Caballero, I'm from Mexico. I use Landsat for monitoring change in forest ecosystem, biomass calculation, habitat fragmentation, and analysis.

Hi. Beth Tellman from Tucson, Arizona in the United States. I use Landsat to map floods in near real time, and going back several decades, and I also use it to map urbanization and measure deforestation.

Hello, I’m Janet Antonio from the Independent University at the State of Mexico. I have used Landsat for 21 years to document the forests and its forestry processes, such as fragmentation, deforestation and fires. Landsat has been an incredible tool for my research and teaching activities.

Hello. My name is April. I'm an innovation researcher who's based in Thailand. I'm using Landsat for studying about pollution and carbon sequestration and also detecting land use land cover change.

Hi. My name is Bex Dunn. I'm an Earth observation scientist in Canberra, Australia, and I use Landsat to characterize wetlands through time.

Hello. My name is Laura Chasmer. I'm an associate professor in the Department of Geography and Environment at the University of Lethbridge in Alberta, Canada. I am using Landsat combined with Lidar data to understand the cumulative impacts of disturbance on patterned fens in northern Canada.

Hello. My name is Nikki Tulley. I'm a member of the Navajo Nation located in the Western United States. I use Landsat to study the impacts of climate change. Namely, drought. With this information, I work to help communities and decisionmakers make informed decisions on the changing landscapes.
