|Welcome to Bolton's Online GIS service. Residents can now view a variety of GIS maps and data specific to the Bolton area. The Bolton GIS-QMO site includes several tools:
- Map navigation/analysis/output - zoom, pan, measuring, graphics editing, printing etc.
- Assessor parcel data - display the Property Record Card from a parcel or address viewed on the map or apply various abutters tools (Please note that results generated by the abutters tools are unofficial. Contact the Assessors office in town hall for official abutters lists and information)
- Permitting data - there is also a cross link to Bolton's online permitting data which allows quick access to permit information from a parcel or address viewed on the map.
Bolton GIS maps are organized in selectable layers. You can choose to display only those layers that you are interested in by checking or clearing the appropriate check boxes. For example when you first open the Bolton GIS site you'll see a "MapLayers" heading which you can expand to view all the layers available for selection. The "Base Map" layer is selected by default. Clicking on the "200 ft Riverfront Resource Area" layer will display the 200 ft buffer along river fronts. You can zoom in to see how close buildings are to this buffer area.
Special Notes for Map Layers:
- The relative proximity displayed and distances measured on the maps are approximate only. These results can only be used for informal planning or general analysis. You may need to contact professional surveyors for precise, official results.
- The Zoning Layer has had some recent changes not yet reflected in the online version. The latest version of the Zoning Layer is available at the town hall.
The actual map data comes from Mass GIS, CAI Technologies (a long time Bolton vendor providing Assessor and Mapping services), and/or from customized information developed by Town Hall staff (Assessors, Conservation, IT, Planning). Our collection of customized, Bolton specific, GIS data will continue to grow and evolve. As an example Conservation's Trail Committee is in the process of mapping trails throughout Bolton using mobile devices and GPS apps. This GPS data will be imported into our GIS database, edited for accuracy and relevance, and then published as a new layer on the Bolton GIS site. We expect to be publishing new data 1-2 times per year.
Most of the tools are self explanatory and the "Help" button on the web site should address any questions. Some of our neighboring towns have also published detailed instructions that you may find useful ( Wayland Ma instructions )
