This is an index of the 1:24,000-scale U.S. Geological Survey (USGS) 7.5-minute topographic quadrangle maps that cover the State of Connecticut. The index includes a polygon feature for each 7.5-minute quadrangle area. These data are for making a Quadrangle Index-based Mapbook Series. Mapbook is a developer's sample created by ESRI. It is an addition for ArcMap that allows the layout created in an ArcMap document to be used repeatedly to generate a series of similar maps. The extent of each map is controlled by the polygon features of the datalayer designated as an index. Attributes of the index are tagged to and used to change text on each map in the series.
These data are suitable for making a Mapbook Series using the Quadrangle Index as a spatial index. Not intended for use in a conventional GIS mapping or spatial analysis application.

None. No restrictions or legal prerequisites for using the data after access is granted. These data are only suitable for use in creating a spatial index for a Mapbook Series based on USGS Quadrangle Index. Not intended for use in a conventional GIS mapping or spatial analysis application.

All attributes have valid values. Values are within defined domains. The polygon attributes were manually entered.
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. No tests of logical consistency were performed by the State of Connecticut.
The degree of completeness is based on the extent to which the data covers the geographic area of the State of Connecticut. The layer is complete because it includes quadrangle index polygon features for all of Connecticut, including areas defined by 7.5 minutes of latitude and longitude where the USGS published 1:24,000-scale topographic quadrangle maps and areas of 7.5 minutes of latitude and longitude entirely covered by water (in Long Island Sound) where the USGS did not publish 7.5 minute topographic quadrangle maps.
The horizontal positional accuracy of this data complies with the United States National Map Accuracy Standards for 1:24,000 scale maps.
