All of these sources were utilized to identify and verify city names. The source data used to create the city limits coverage is several years old. The problem exists that some cities change their municipal boundaries over time, and that some city limits in this coverage may be out of date. For example, the City of Tallahassee has extended its city limits since the creation of the source data set. Please contact Paul O'Rourke with any questions or concerns pertaining to the city limits coverage.
Scale is an important factor in data usage.
Certain scale datasets are not suitable for some project, analysis, or modelling purposes. Please be sure you are using the best available data. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analyses. Every effort has been made to supply the user with data documentation.
