OVERVIEW

These coverages are the Cape Cod Commission GIS department's datalayers that are the result of data development at the CCC GIS since 1988. These themes, delivered to MassGIS for general distribution statewide, are those most extensively used by the Commission’s programs and have been created primarily to support the Commission's Regional Policy Plan and Local Comprehensive Plans with each of the fifteen towns of Cape Cod. These coverages also have value to other agencies, especially the towns that the CCC works for, as well as State and Federal agencies. Some layers used by the CCC and released to MassGIS were digitized from the 1990 Association for the Preservation of Cape Cod (APCC) Atlas.

Three towns on Cape Cod -- Barnstable, Orleans, and Yarmouth -- have their own GIS and have developed many GIS layers. Yarmouth has chosen to maintain control of the distribution of data the town has developed, and has requested that the CCC and MassGIS not redistribute their parcel coverages. 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.

Some of the coverages are near-duplicates of layers developed by other state agencies, such as public water supplies (Mass. DEP) or anadromous fish runs (Fisheries and Wildlife). 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. Most importantly, layers developed by DEP that may have influence in regulatory matters (i.e. solid waste facilities, zone IIs) may be more complete and should be used instead of those from the Cape Cod Commission.

Most of the coverages the Cape Cod Commission provided to MassGIS were digitized from paper maps using a Calcomp 9100 digitizer and ARC/INFO. Source material varies by layer. Some original manuscripts were obtained from the 1990 APCC Atlas; others came from town sources. 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.

MassGIS has populated two ARC/INFO libraries with the CCC datasets. The CAPE library comprises cape-wide or multi-town layers. The CAPETOWN library consists of layers for single towns. The following are lists, with brief descriptions, of each library’s layers.

In order to preserve all original attribute information as originally developed by either the towns or the Cape Cod Commission, the polygon attribute tables for the parcels and zoning layers are available as related INFO tables in the $CAPETOWN/database directory. Because the items differ among the original .PATs, these tables can be used to relate to individual coverages rather than the library as a whole, based on the ‘-ID’ items. Two sets of tables exist: the original parcel .PATs are named according to their three-letter character designations given to the towns of Cape Cod by the USGS plus the letters ‘PAR’ along with a ‘.PRT’ extension; original zoning .PATs have the three-letter code with ‘ZON’ and a ‘.PRT’ extension. Relates also can be set up using another INFO table in $CAPETOWN/database - TOWNCODE.DAT, which contains the three-letter USGS code (‘CAPECODE’), town and town-id. 

TOWNCODE.DAT is as follows:

CAPECODE TOWN          TOWN-ID
A1W      BARNSTABLE    20
BHW      BOURNE        36
BMW      BREWSTER      41
CGW      CHATHAM       55
DGW      DENNIS        75
EGW      EASTHAM       86
FSW      FALMOUTH      96
HJW      HARWICH       126
MIW      MASHPEE       172
OSW      ORLEANS       224
PZW      PROVINCETOWN  242
SDW      SANDWICH      261
TSW      TRURO         300
WNW      WELLFLEET     318
YAW      YARMOUTH      351

As an example of the original .PATs, the original parcel .PAT for Barnstable is named A1WPAR.PRT. 

Original metadata for the $CAPETOWN library created by the Cape Cod Commission are stored as Info files in directories under the $CAPETOWN/database directory (parmeta, pipmeta, sewmeta, and zonmeta). These files are named according to the three-letter CAPECODE and have a .CCC extension. The original .DOC, .PAD, .PAC, .AAD, and .AAC files, if available, are stored here as well. Original metadata (with the .CCC extension) for the $CAPE library are stored as Info files in $CAPE/database. Some of these .CCC files may mention ‘NAD27' or ‘stateplane feet,’ referring to original datums. All data from the Cape Cod Commission have been projected into Mass. State Plane NAD83 meters.

MassGIS is not maintaining these data. Future updates of any of these layers will be done by the Cape Cod Commission GIS staff prior to subsequent release by MassGIS. For current status of any of the aforementioned datasets please contact Gary Prahm, GIS Manager at the Cape Cod Commission, at (508) 362-3828.
