CSS leads USGS’s mission as the civilian mapping agency for the Nation. We conduct detailed surveys and develop high quality, highly accurate topographic, geologic, hydrographic, and biogeographic maps and data. Our maps allow precise planning for critical mineral assessments; energy development; infrastructure projects; urban planning; flood prediction; emergency response; and hazard mitigation.
National Geospatial Program
The National Geospatial Program is the Federal civilian mapping agency and provides the digital geospatial foundation for the Nation. It engages partners and communities of use to collaboratively produce consistent and accurate topographic map data.

USGS Upgrades, Improves Earthshots Page Featuring Stories of Change
The USGS Earthshots website, managed by the Communication & Outreach department at the Earth Resources Observation and Science (EROS) Center, shows the value of observing the Earth with satellites at a level that (we hope) non-scientists can understand.
Mapping Urban Heat Islands Leads NYC Council Data Team to Landsat
New York City (NYC) loses an average of 13 residents each year to heatstroke. The NYC Department of Health and Mental Hygiene estimates more than 100 die each year from other causes associated with extreme heat. Hundreds visit emergency departments, with an average of 150 hospitalized annually.

Drought stress and hurricane defoliation influence mountain clouds and moisture recycling in a tropical forest
Mountain ranges generate clouds, precipitation, and perennial streamflow for water supplies, but the role of forest cover in mountain hydrometeorology and cloud formation is not well understood. In the Luquillo Experimental Forest of Puerto Rico, mountains are immersed in clouds nightly, providing a steady precipitation source to support the...
Scholl, Martha A.; Bassiouni, Maoya; Torres-Sanchez, Angel J.Identification of Global Priorities for New Mountain Protected and Conserved Areas
Mountain ecosystems are extremely diverse and fragile. They include astonishing biodiversity in terms of number of taxa and endemicity, and globally provide the most diverse range of ecosystem services. The world’s system of protected and conserved areas includes many outstanding areas within the earth’s mountainous landscape: about 19% of...

Studies integrating mangrove in-situ observations and remote sensing analysis for specific sites often lack precise estimates of carbon stocks over time frames that include disturbance events. This study quantifies change in mangrove area from 1985 to 2018 with Landsat time series analysis, estimates above and belowground stored carbon...
