This core GIS application can be viewed in any desktop browser or mobile device. Users are able to access assessment information, deeds, property cards, and pictures. Several data sets are available for overlay including: utilities, parcel annotation, districts, such as Fire and Zoning, and environmental data. Users can also toggle between several years’ worth of orthophotography and different themed basemaps, as well as produce high quality GIS maps, and perform spatial operations like buffer notifications. The values shown are based on the findings during the 2021 Town Wide Revaluation, and the land & building characteristics are based on the findings for the 2021 Grand List.
Groton also offers several smaller, task-oriented applications. While the data served is exactly the same as that found in the main GIS Viewer, some additional task-specific tools are provided in each app and default layers and settings are better tailored toward the app's theme:
FEMA Flood Maps
FEMA flood maps are flood hazard information produced by the National Flood Insurance Program (NFIP). FEMA mapping identifies flood hazards and evaluates flood risk areas. FEMA has partnered with states and communities to provide accurate flood hazard and risk data to guide them to mitigation actions.
Voting District Map
UPDATED WITH REVISED 2022 DISTRICT BOUNDARIES & POLLING LOCATIONS
This application is designed to help users find a voting location within the town. Click a location directly on the map to find a voting location or search for the address of your polling place in the search bar. When a polling location is within the polygon layer, you will see information about the polling location and the related district boundary will be highlighted on the map.

Guide to Hiking Trails
Want to go on a hike? This web application allows users to view trails on their PC, tablets or smartphone. It includes trail facts, downloadable maps, the ability to create your own trail map, and a "find my location" tool to use when you're out on a trail. The trail systems include Town of Groton, State, and private Open Space trails, managed by Groton Open Space Association (GOSA) and the Avalonia Land Conservancy.
This application helps citizens locate a park and obtain information about recreational activities in their community. Searches can be conducted by park name or amenity within the park. This application is typically used to locate a park or recreation area near you, or one that offers the activity you are interested in.
This application allows users to view locations where the public can access Groton's coastline. Just click on one of the coastal location photos to the right and the map will zoom to its location. Display a window showing basic information by clicking on a coastal area in the map. View photos from the area by clicking on the camera icon on the map. We are currently working on a replacement for this legacy app.
New London County ParkRx
New London County Parks and Recreation Departments have come together to create the New London County Park Prescription program. This program has partnered with public land agencies and healthcare providers to encourage people to utilize parks, trails, and open space for the purpose of improving individual and community health. You can search for the closest park to you by typing in an address in the search bar or clicking a location button directly on the map; a list of amenities in your area will then appear.
