New Coastal New Hampshire Online Mapping Tool Improves Access to Information and Maps

coastalviewer2The New Hampshire Department of Environmental Services (NHDES) in collaboration with the University of New Hampshire’s GRANIT System and other project partners are excited to launch the New Hampshire Coastal Viewer, an online mapping tool that gives anyone with an Internet connection the ability to access more than 150 spatial data sets and to make and share their own customized maps.

For the first time, the Coastal Viewer brings both new and existing coastal resources and hazards-related spatial data sets in the 42 communities of N.H.’s coastal watershed together in one place. Examples of this data include conservation and public lands, salt marsh and eelgrass maps, aerial imagery, FEMA floodplains, storm surge and sea-level rise information, infrastructure, and culverts data. Some of the features of the Coastal Viewer include the ability to search, display and query data sets; customize the color of the displayed data; and make, share and print maps.

The Coastal Viewer is intended for a wide variety of users who want access to data sets and mapping tools for planning and education purposes, including municipal staff and volunteers, state and regional government staff, business owners, community members and researchers.

The Coastal Viewer was developed by NH GRANIT as part of a project funded by the National Oceanic and Atmospheric Administration Office for Coastal Management and coordinated by the NHDES Coastal Program. The data on the Viewer comes from many sources and is available through the cooperation of federal and state agencies and regional organizations such as: NHDES, The Great Bay National Estuarine Research Reserve, the Piscataqua Region Estuaries Partnership, the Rockingham and Strafford Regional Planning Commissions and many more. New and updated datasets will be continually added to the Viewer as they become available. NH GRANIT can be contacted at or by calling GRANIT Project Director Fay Rubin at 603-862-4240.
