Overview of Online Map Services

Online map services provide the general public with free access to GIS tools through the Internet. With these services, users can:

• Interact with maps (zoom in/out, search for a location, query geographic data, customize the map content)
  
• Create a map for output to a local printer
• View geographic data from a variety of sources (local, state, federal government)
• Access data documentation (metadata)
  
• Contribute to GRANIT data holdings

The following services are currently available:

NH GRANIT Data Mapper

The NH GRANIT Data Mapper is a web-based mapping tool offering New Hampshire's communities, agencies and organizations, and the general public access to a comprehensive collection of geospatial data archived in GRANIT. Our hope is that the data and related tools will be utilized to inform and expand decision-making at the local, regional, and statewide levels.

We thank the NH GIS Conservation Collaborative for their generous support of this project.

NH GRANIT Town Boundary Monument Catalog

The NH GRANIT Town Boundary Monument Catalog is a statewide inventory of spatially referenced town monuments.The primary objectives of the Catalog are to:

• Build, document, and maintain a GIS-based inventory of town boundary monuments in New Hampshire.
• Provide a comprehensive resource to town officials, land surveyors, and others in the state who are researching issues related to town boundary lines and monumentation.

Over time, this resource will be used to improve the accuracy of town boundary mapping in the state and produce a better digital representation of the corporate jurisdictions.

Registered users of the Catalog may submit coordinates and related information for current and/or historic collections of town monuments. These data are made available to the public via the Catalog and the NH GRANIT Data Mapper Geodetic Control Theme.

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.
