Web Services


GRANITView is a web-based mapping tool, initially released in April of 2014, offering New Hampshire's communities, agencies and organizations, and the general public access to a comprehensive collection of geospatial data archived in GRANIT. It includes data display, navigation, query, sketching, measuring, and printing tools. Our goal is to ensure that the data and related tools will be utilized to inform and expand decision-making at the local, regional, and statewide levels.

NH Coastal Viewer

The NH Coastal Viewer is an online mapping tool that provides access to coastal resources spatial data, hazards-related spatial data, and other spatial data sets within NH's 42 coastal watershed communities.

NH Stone Wall Mapper

The NH Stone Wall Mapper site is a web mapping tool that allows the public to record the locations of stone walls based on viewing and interpreting LiDAR data sets.

NH Wildlife Sightings

The NH Wildlife Sightings site is a web tool to report observations of rare wildlife in NH. All data collected through the site are forwarded to wildlife professionals at the NH Fish & Game Department, who review and verify the individual records. Verified records then go to the NH Natural Heritage Bureau for storage and use within their statewide database of tracked species. Finally, information from the updated NH Natural Heritage Bureau's database return to the website for display to the viewer at the town scale.
