This coverage contains points that represent populated places, ie. cities, towns, villages or any other named place where
people live. The coverage was developed from the USGS Geographic Names Information System (GNIS) database for Iowa. There
were many errors in the original GNIS data, including missing points or mislocated points. The GNIS points were compared to
two reference sources: USGS 100k scale county maps and Iowa DOT county highway maps. Mislocated and missing point were fixed
and each town was designated as having been verified from one or the other reference sources or both. Some GNIS points were
not verified from either source and are so designated (use these with caution).

Use limitation statement:
This digital, geographically referenced data set was developed by the Iowa Department of Natural Resources to carry out agency
responsibilities related to management, protection, and development of Iowa's natural resources. It resides in the Natural
Resources Geographic Information System library. Although efforts have been made to make it useful to the Department, the
Department assumes no responsibility for errors in the information. Similarly the Department assumes no responsibility for
the consequences of inappropriate uses or interpretations of the data made by anyone to whom this data has been made available.
The Department bears no responsibility to inform users of any changes made to this data. Anyone using this data is advised
that precision implied by the coverage may far exceed actual precision. Comments on this data are invited and the Department
would appreciate that documented errors be brought to staff attention. The development of the coverages in the NRGIS Library
represents a major investment of staff time and effort. As a professional responsibility, we expect that the Iowa DNR will
receive proper credit when you utilize these GIS coverages and that the original documentation will remain with any redistribution
of these coverages.

evaluation Method Description
The positional accuracy of the original GNIS data is 5 seconds of latitude or longitude. In Iowa, this translates to 100 to
150 meters. All data points were examined and those that were obviously mislocated were moved. A small number were found to
be outside of their incorporated boundary line and were moved inside.
