OVERVIEW

These two statewide boundary layers are used by the Center for Environmental Health (CEH), Massachusetts Department of Public Health (MDPH) for planning and administrative purposes. The source material for these datalayers was compiled by Christina Kara, Center for Emergency Preparedness (CEP), MDPH. The two layers are:

• Emergency Preparedness Regions - REGDPHEP_POLY
• Emergency Preparedness Regional Coalitions - REGDPHEPC_POLY. Regional coalitions belong to larger Emergency Preparedness Regions.

Staff at the GIS Program, Center for Environmental Health, Massachusetts Department of Public Health developed the data. In Access 2000, the Regional Coalition infomation was joined to the attribute table of the MassGIS Community Boundaries from Survey Points datalayer based on town name. Using ESRI's ArcMap 9.0 software, a dissolve was performed on the Community Boundaries layeron Regional Coalition name. The new feature class was renamed. In Access 2000, the Region field was manually inserted into the attribute table using the original Regional Coalition information as a reference. To produce the Regions layer, polygons were created based on a dissolve on the Region field in the Coalition layer.

Both polygon layers have the field REGION, which is the MDPH Administrative Region Name. The Coalitions layer also has the field REG_COAL, which is the MDPH Administrative Regional Coalition Name.
