Connecticut Planning Region Index is a 1:125,000-scale polygon feature-based layer that includes a polygon feature for every Connecticut Regional Planning Organization. There are 14 polygon features in this layer. The corresponding Regional Planning Organization number and name attributes uniquely identify individual polygon features. The Regional Planning Organization number values are based on an alphabetic sort of Regional Planning Organization names and range from 1 to 14.
For additional information, contact the Connecticut Office of Policy and Management.

Connecticut Planning Region Index is a general purpose index map of Connecticut Planning Regions based on mapped information compiled at 1:125,000 scale (1 inch equals approximately 2 miles) and a list of towns in each region available from the State of Connecticut, Office of Policy and Management. The layer is designed to be used to depict Connecticut Planning Regions at small scales or on small maps printed on regular size (8.5 x 11 inch) paper, for example. This Planning Region Index layer does not accurately represent planning region boundaries because it was digitized at 1:125,000 scale. Do not display, map or analyze this index layer with information collected at larger scales. To depict more accurate 1:24,000-scale Connecticut state, county, town, and planning region boundaries on a map, use the layer named Town, which is also published by the State of Connecticut Department of Energy and Environmental Protection. The 2012 Edition reflects consolidation of two organizations into the Lower Connecticut River Council of Governments.
Town_Index.shp was originally in ArcInfo Coverage format and digitized in 1986 using the Connecticuct State Plane Coordinate System, North American Datum of 1927 (NAD27). In 1999, the data was converted to ESRI Shapefile format and to the Connecticut State Plane Coordinate System, North American Datum of 1983 (NAD83). The 2005 edition includes complete metadata. Town_Index.shp is in Shapefile format. Prior to 2005, this shapefile was named Town.shp. Town_Index is based on boundary information published on a 1;125,000-scale U.S. Gelogical Survey planimetric map of the State of Connecticut. The planimetry for this map was revised in 1974.
Planning_Region_Index.shp is in Shapefile format. Prior to 2005, this shapefile was named PlanOrg.shp. The 2005 edition includes complete metadata.
Planning_Region_Index is in GeoDatabase Feature Class format.
Create Planning Region Index layer - Planning Region Index is derived from the 1:125,000-scale Town Index layer, which is also published by the State of Connecticut, Department of Energy and Environmental Protection. To derive planning region polygon features from town polygon features, town features were attributed with regional planning organization number and name values. Town polygon features in the same region were then merged to form fourteen polygon features, one for each planning region. The TOWN_NO and TOWN attributes from the Town Index layer were replaced with RPO_COD and REGPLANORG attributes that store regional planning organization number and name, respectively.

Convert to GeoDatabase Feature Class format - Defined new Feature Class named Planning_Region_Index; and imported the attribute definitions, loaded features and imported metadata from Planning_Region_Index.shp shapefile. Spatial Reference Properties for Feature Class: Coordinate System: NAD_1983_StatePlane_Connecticut_FIPS_0600_Feet XY Domain MinX: 100000; MaxX: 2247483.645 XY Domain MinY: 200000; MaxY: 2347483.645 Precision: 1000

All attributes have valid values. Values are within defined domains. The Regional Planning Organization number and name polygon attributes were manually entered.
The horizontal positional accuracy of this data is unknown. Avoid displaying or printing this information at map scales greater than 1:125,000 (1 inch equals approximately 2 miles).
The completeness of the data reflects the feature content of two data sources - a 1:125,000-scale planemetric map of Connecticut published by the U.S Geological Survey and a list of towns in each planning region available from the State of Connecticut, Office of Policy and Management. This data is updated as needed based on information from the State of Connecticut, Office of Policy and Managment.
Polygon features conform to the following topological rules. Polygons are single part. There are no duplicate polygons. Polygons do not self overlap. Polygons do not overlap other polygons. Establishment of logical consistency was orginally performed by the State of Connecticut, Department of Environmental Protection using ESRI ArcInfo software to manually create and control feature topology. The original minimum distance between vertices (ArcInfo Coverage fuzzy tolerance) and a minimum allowed overshoot length (ArcInfo Coverage dangle length) were not documented and unknown at the time this metadata was created in 2005. However, the original data was known to be topologically clean. After subsequently converting the data from ESRI ArcInfo Coverage to ESRI Shapefile format, no automated procedures or tests were performed to enforce the topology rules other than visual inspection.
No restrictions or legal prerequisites for using the data. The data is suitable for use at appropriate scale, and is not intended for maps printed at scales greater or more detailed than 1:125,000 scale (1 inch equals approximately 2 miles).
