Index to the Lehman Scanned Map Collection is a polygon theme that serves as an index to scanned sheets from the Lehman Map collection. Each feature represents the approximate extent of a map sheet or map set. Attribute information includes the name of the map, a url to the metadata record in the CUL Spatial Data catalog and a url to a thumbnail detail of the map. This dataset will be updated regularly.

Data Quality Information
Attribute Accuracy Report
The attributes of each feature have been checked individually for accuracy. There is the possibility that the URLs will change with time.
Horizontal Positional Accuracy Report
The 'footprints' of the map are generated from the maximum extent values of the map sheets following a georeferencing process. As such the locations are highly approximate and may be inaccurate, particularly for small scale maps and maps that are not oriented with north at the top.
