Title: Massachusetts (Community Health Centers, 2007)
Contributors:- Point data
- 2007
Summary: This point datalayer contains the location of community health centers (CHCs) in Massachusetts. The layer was produced by the Massachusetts Department of Public Health (MA DPH) Center for Environmental Health (CEH) GIS program. The source material was provided by Tina Ford Wright, Publications and Marketing Assistant, Massachusetts League of Community Health Centers, a.k.a. "the League," (http://www.massleague.org). The League defines a community health center as a non-profit community-based organization that offers comprehensive primary and preventive health care, including medical, social and/or mental health services, to anyone in need regardless of their medical status, ability to pay, culture or ethnicity.The layer is named CHCS_PT.CHCs are grouped into Main and Satellite locations. Main CHCs may have one or more satellite locations (also known as access points). The MCHC_CODE item defines the affiliation between main CHCs and their satellites.CHCs vary by both the facility and/or building type in which they are located, scope of clinical services offered, and target patient population(s). The CEH GIS program used the MassGIS Hospitals, Schools, Colleges and Universities, and Prisons datalayers, and Internet Web sites in the case of homeless shelters, to derive the locations of health centers in these facilities. Health centers known to be administrative offices are attributed accordingly. With respect to clinical services, this GIS datalayer makes no distinction among CHCs. An exception is eye care and dental service providers that are indicated in the EYE and DENTAL fields. No information regarding target patient populations is explicitly defined, though assumptions may be based on health center name and/or location.In all cases, patients seeking care should contact the CHCs directly to verify availability of clinical services, hours, etc., rather than rely on the information contained in this GIS datalayer, as such information is subject to change.

Summary: This datalayer is a point shapefile that shows long-term (1931-1960) mean monthly values for actual evapotranspiration (AE) (in millimeters) on a global terrestrial grid at 0.5 degree longitude/latitude spatial resolution. The dataset is a derived portion of the Global Climate Database (May 15, 1996) which is an updated version of the IIASA database for mean monthly values of temperature, precipitation and cloudiness on a global terrestrial grid (1991), first produced by Rik Leemans and Wolfgang Cramer, and published by the International Institute of Applied Systems Analyses and also distributed by the National Institute of Public Health and Environmental Protection (Netherlands). This version of the datalayer appears as part of the USGS Global GIS : global coverage database (2003). The evapotranspiration scheme used is developed by Prentice et al. Its reference is: Prentice, I.C., Sykes, M. Cramer, W., 1993. A simulation model for the transient effects of climate change on forest landscapes. Ecological Modelling, 65: 51-70. The USGS Global GIS database contains a wealth of USGS and other public domain data, including global coverages of elevation, landcover, seismicity, and resources of minerals and energy at a nominal scale of 1:1 million. The U.S. Geological Survey (USGS) and The American Geological Institute (AGI) announced a cooperative agreement that will focus on making the USGS Global Geographic Information System (GIS) database readily available to educators and the general public in the form of a DVD based world atlas.

This version of the datalayer appears as part of the USGS Global GIS : global coverage database (2003). Cloud Coverage or Cloudiness is defined as the actual number of bright sunshine hours over the potential number, and is thus expressed as a percentage figure. A high percentage means more sunshine and fewer clouds. The USGS Global GIS database contains a wealth of USGS and other public domain data, including global coverages of elevation, landcover, seismicity, and resources of minerals and energy at a nominal scale of 1:1 million.

Title: MassGIS 2003 Massachusetts Surface Water Supply Protection Areas (Zone B) (Region Polygons) (March 2003)
Contributors:- Polygon data
- 2003
Summary: This datalayer consists of polygons representing Massachusetts Surface Water Supply Protection Zone regions (Zone B). (See also the Surface Water Supply Protection Zones (Zone B) (Polygons) datalayer.) Three datalayers (ZONE A, ZONE B, ZONE C) delineate those areas included in 310 CMR 22.00, the Massachusetts Drinking Water Regulations, as Surface Water Supply Protection Zones: ZONE A: represents a) the land area between the surface water source and the upper boundary of the bank; b) the land area within a 400 foot lateral distance from the upper boundary of the bank of a Class A surface water source, as defined in 314 CMR 4.05(3)(a); and c) the land area within a 200 foot lateral distance from the upper boundary of the bank of a tributary or associated surface water body. ZONE B: represents the land area within one-half mile of the upper boundary of the bank of a Class A surface water source, as defined in 314 CMR 4.05(3)(a), or edge of watershed, whichever is less. Zone B always includes the land area within a 400 ft lateral distance from the upper boundary of the bank of the Class A surface water source. ZONE C: represents the land area not designated as Zone A or B within the watershed of a Class A surface water source, as defined in 314 CMR 4.05(3)(a). All known surface water supplies have zones delineated, but some may be covered by other legislation. Areas with a status value of M are included for reference but are not covered by 310 CMR 22.00. Each area is delineated in a separate datalayer, Zone A, Zone B, and Zone C.
