Advancing Land Change Modeling: Opportunities and Research Requirements

People are constantly changing the land surface through construction, agriculture, energy production, and other activities. Changes both in how land is used by people (land use) and in the vegetation, rock, buildings, and other physical material that cover the Earth's ...

Landsat and Beyond: Sustaining and Enhancing the Nation's Land Imaging Program

In 1972 NASA launched the Earth Resources Technology Satellite (ETRS), now known as Landsat 1, and on February 11, 2013 launched Landsat 8. Currently the United States has collected 40 continuous years of satellite records of land remote sensing data ...

Precise Geodetic Infrastructure:National Requirements for a Shared Resource

Geodesy is the science of accurately measuring and understanding three fundamental properties of Earth: its geometric shape, its orientation in space, and its gravity field, as well as the changes of these properties with time. Over the past half century, ...

Mapping the Zone:Improving Flood Map Accuracy

Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps portray the height and extent to which flooding is expected to occur, and they form the basis for setting flood insurance premiums and regulating development in the floodplain. As such, they ...

Review of NASA's Solid-Earth Science Strategy

The report reviews NASA's solid-earth science strategy, placing particular emphasis on observational strategies for measuring surface deformation, high-resolution topography, surface properties, and the variability of the earth’s magnetic and gravity fields. The report found that NASA is uniquely positioned ...

National Land Parcel Data: A Vision for the Future

Land parcel data (also known as cadastral data) provide geographically referenced information about the rights, interests, and ownership of land and are an important part of the financial, legal, and real estate systems of society. The data are used by ...
