Yarmouth should be contacted to obtain copies of its digital data. Files for Yarmouth that are distributed by MassGIS have been developed by the CCC and do not carry this restriction. The Cape Cod Commission requests that use of any of its coverages or data bases to generate maps, analyses, or reports be followed by a credit to the Cape Cod Commission as the source of the data. MassGIS is releasing both the layers developed by the Cape Cod Commission and those from various state agencies. Users should note the source dates of each layer.
Source material varies by layer.
Other layers were produced with on-screen digitizing in Arcedit. Attribute information for parcel and zoning coverages came from town planning and engineering departments and assessors databases. MassGIS performed quality checking on all layers and standardized all attrribute tables before creating the libraries. The following are lists, with brief descriptions, of each library s layers. See chart below for source date of assessor s attributes for each town.
