We provide our GIS maps in the form of Google Earth, Google Maps and PDF files.
The following maps can be viewed with any PDF viewer. They are formatted for super B size paper (13″ x 19″) and can be printed by any local print service company. Printed copies are available for viewing at Town Hall. Note that these maps identify parcels by lot numbers and you will need a copy of the current tax database (see above) to determine parcel owner names and tax information.

General Note Regarding Parcel Maps
Refer to the tax database spreadsheets above for the current parcel owner and tax information. These spreadsheets are updated throughout the tax year.
The data provided in the tax map are for planning purposes only. Although considerable time and grant-money has gone into making them as accurate as possible, some inaccuracies undoubtedly remain. They were created from the paper maps tax maps that the town inherited from the City of Portland after secession. Those paper maps were imperfect to begin with and degraded further over time. The town believes that these data are accurate enough for planning and taxation; however, like any tax map, they represent only an estimate of the location of lot boundaries and the size and shape of lots. Only a professional survey can determine the exact boundaries and size of your property.
That said, if you believe that the maps provided here contain errors that would render town planning and taxation work inaccurate, the town may, after consideration, adjust the data to produce are more accurate depiction of your lot characteristics. If you wish to submit changes, please consult with our GIS assistant. Call Town Hall to set up an appointment.
