The National Conservation Easement Database (NCED) is a national database of conservation easement information that compiles records from land trusts and public agencies throughout the United States, and aims to help agencies, land trusts, and other organizations plan more strategically and identify opportunities for collaboration.
The National Estuary Program (NEP) is a network of voluntary community-based programs that safeguards the health of important coastal ecosystems across the country. The National Estuary Program Mapper (NEPmap) is an interactive map that allows users to obtain detailed information about Natural Estuary Program Study Areas, including watershed boundaries and land ownership information, as well as soil types, development status, impervious cover, population, and water quality data.
The National Map (formerly “National Atlas”) is a Department of Interior map-making tool that helps researchers analyze issues related to climate change, carbon in the environment, biodiversity loss, and changes in ecosystems.
The National Wetlands Inventory uses topographical maps to show wetlands and deepwater habitats.
Open-source Nonpoint Source Pollution and Erosion Comparison Tool (OpenNSPECT) is a GIS tool that helps conservation practitioners quickly and easily identify land areas that generate high sediment and nonpoint source pollutant loads. OpenNSPECT’s scenario analysis functionality allows people to test the relative effectiveness of different land cover management options on sediment and pollutant yields.
Land cover maps depict where and how much of a region is covered by forests, wetlands, development, and other natural and man-made features. Documenting changes in the landscape can alert communities to emerging trends, information that is useful when predicting and assessing cumulative impacts in the light of climate stressors, such as sea level rise.

The Sea Level Affecting Marshes Model (SLAMM) is an online tool that allows the public to view simulations of sea level rise. This program is designed to help people understand the potential impacts of climate change on sea levels. This web browser-based application displays map pairs of the same area, each at different sea levels.
The U.S. Interagency Elevation Inventory provides a comprehensive listing of known high-accuracy topographic and bathymetric data for the U.S. and its territories. Elevation data is necessary to develop coastal elevation models and are critical components when looking at sea level rise, coastal flooding, beach nourishment, erosion, or any other processes that occur within the land-water interface.
