Mapbook Town Index

Frequently-asked questions:


What does this data set describe?

Title:
Mapbook Town Index

Abstract:
A 1:125,000-scale polygon feature-based layer of Connecticut towns. These data are for making a Connecticut Town 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.

  1. How should this data set be cited?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    All attributes have valid values. Values are within defined domains. The Town number and Town name polygon attributes were manually entered based information depicted on a map of the state of Connecticut.

  2. How accurate are the geographic locations?

    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).

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    The completeness of the data  reflects the feature content of the data source, which is a 1:125,000-scale planemetric map of Connecticut published by the U.S Geological Survey. This data is not updated.

  5. How consistent are the relationships among the observations, including topology?

    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.
