The Town converted its existing analog tax maps to digital format in 1998. At the time of conversion, tax maps consisted of 108 27"x39" mylar sheets at 1"=100', originally created in 1957 from controlled and rectified photography taken by Air Survey Inc. (VA) in 1956. The tax maps were scanned, and digital line files were created with text annotation. The new line files were then overlayed onto digital color orthophotos produced in 1999, and updated, by first matching road right-of-ways, then adjusting all parcel boundaries. This data set is a spatial view that is created through a one-to-many join between TOA_Parcels_Poly and TOA_CAMA_TABLE. The join is through Map & Lot, which creates stacked parcel polygons in cases where there are multiple block numbers (accounts) for one parcel; this occurs primarily with condominium complexes, as well as with properties with agricultural preservation restrictions. This data set is refreshed on a nightly basis & reflects current information from the Town of Amherst Assessor's Vision Appraisal Database.

This data is also available for download in shapefile and CAD formats.The Town of Amherst, MA basemap project encompasses the land area of Town of Amherst and University of Massachusetts Campus with a 200 foot fringe surrounding the area. The entire project area has been sub-divided into 5 blocks, viz. Amherst/UMass, Area A (primarily Leverett), Area-B (Shutesbury/Pelham/Belchertown), Area-C (Hadley) and Area D (UMass-owned land at Deerfield). Basemap data was collected at 1" = 40' mapping scale for Amherst (31.1 sq. miles) and Area-D (1.3 sq. miles) using digital photogrammetric techniques. LiDAR data was collected for the entire project area except Area-D to develop 1ft contour data. LiDAR data was supplemented with photogrammetrically collected breaklines, hydro and other terrain features over the Amherst block to generate 1ft contours. For rest of the area the bare earth classified LiDAR data was supplemented with hydro enforced breaklines to generate the 1ft contour data.

Tree Inventories from 2008 and 2010. Some trees in Amherst Center were inventoried both times. The Street Trees 2009 layer is 99%+ composed of tree points collected as part of the Spring 2009 1"=40' Basemap project. These trees were collected within and in close proximity to street right of ways. The inventory layers can be joined to the Street Trees 2009 layer via their respective IDs.This data is also available for download in shapefile format.
