Resource Abstract:
Property ownership data is compiled from deeds, plats, surveys, and other source data. These are not engineering quality drawings
and should be used for administrative purposes only. The National Park Service (NPS) shall not be held liable for improper
or incorrect use of the data described and/or contained herein. These data and related graphics are not legal documents and
are not intended to be used as such. The information contained in these data is dynamic and may change over time. The data
are not better than the original sources from which they were derived. It is the responsibility of the data user to use the
data appropriately and consistent within the limitations of geospatial data in general and these data in particular. The related
graphics are intended to aid the data user in acquiring relevant data; it is not appropriate to use the related graphics as
data. The National Park Service gives no warranty, expressed or implied, as to the accuracy, reliability, or completeness
of these data. It is strongly recommended that these data are directly acquired from an NPS server and not indirectly through
other sources which may have changed the data in some way. Although these data have been processed successfully on a computer
system at the National Park Service, no warranty expressed or implied is made regarding the utility of the data on another
system or for general or scientific purposes, nor shall the act of distribution constitute any such warranty. This disclaimer
applies both to individual use of the data and aggregate use with other data. NPS Director's Order #25 states: "Land
status maps will be prepared to identify the ownership of the lands within the authorized boundaries of the park unit. These
maps, showing ownership and acreage, are the 'official record' of the acreage of Federal and non-federal lands within the
park boundaries. While these maps are the official record of the lands and acreage within the unit's authorized boundaries,
they are not of survey quality and not intended to be used for survey purposes." As such this data is intended for use
as a tool for GIS analysis. It is in no way intended for engineering or legal purposes. The data accuracy is checked against
best available sources which may be dated and vary by location. NPS assumes no liability for use of this data. The boundary
polygons represent the current legislated boundary of a given NPS unit. NPS does not necessarily have full fee ownership or
hold another interest (easement, right of way, etc...) in all parcels contained within this boundary. Equivalently NPS may
own or have an interest in parcels outside the legislated boundary of a given unit. In order to obtain complete information
about current NPS interests both inside and outside a units legislated boundary tract level polygons are also created by NPS
Land Resources Division and should be used in conjunction with this boundary data.
