Important Notice to ArcServer Users

The Department of Natural Resources and Trust Land Office provide this information with the understanding that it is not guaranteed to be accurate, correct, or complete and conclusions drawn from such information are the responsibility of the user. While every effort has been made to ensure the accuracy, correctness, and timeliness of materials presented the maps shown here are not suitable for site-specific decision-making, or for making financial or any other commitments. Department of Natural Resources, the Trust Land Office, and the Alaska Mental Health Trust Authority assume no responsibility for errors or omissions.


The data may have a number of errors, which may include but are not limited to the following types of errors:

  • Spatial errors: The areas depicted by these maps are approximate, and are not necessarily accurate to surveying or engineering standards. X/Y coordinates may be in error by several hundred feet or more.
  • Registration errors: GIS data layers may not overlay each other correctly.
  • Attribute errors: Database information may be incorrect.
  • Currency errors: GIS data layers, databases and documents may not be the most current available or may not depict the specified time. All data is subject to constant change. Data input lags real-world changes by varying periods of time.
  • Completeness errors: Data may be missing or data may be included that does not belong.
  • Projection distortion: All map projections introduce distortion by representing the irregular shape of the earth’s surface on flat maps. This affects feature shapes and map distances. We choose projections that minimize these distortions when viewing most maps.

To assist the department in the maintenance of the data, users should provide information concerning errors or discrepancies found while using the data to the Trust Land Office at MHTLO@alaska.gov.
