Geographic Information System Maps

Geographical Information System (GIS)

The Assessors Office has published the Town of Douglas GIS (Geographic Information System) online. This online tool will allow all Town Departments, as well as real estate professionals and property owners quick access to the Town maps and a portion of the assessment database.


The GIS shows all parcels in the Town as well as many other information layers, and is updated annually. The GIS will also show you descriptive data relative to each parcel such as parcel identification, location, owner, deed reference, lot size, and assessments, etc. The descriptive data is updated quarterly.
