Lessons Learned w/o QAQC:
Incorrect boundaries in GMPs
Incorrect acreage calculations
National Park Service activities on private inholdings
Planned inventory, monitoring and resource survey projects unaware of possible acquisition or boundary expansions/adjustments.
RED- Boundary used in GMPGreen- Actually park boundary

Having a central boundary conversion provides the opportunity to resolve shared boundaries.

Boundaries are dynamic
Last 10 years:
►73 park units have had legislative boundary expansions.This does not include minor boundary adjustments.►Over 2.7 million acres have been added to the boundaries.►Over 11,244 Tracts have been acquired, totaling over 1.1 million acres.►18 New park units►NPS has interests in 93.14% of the properties in legislative boundaries.
Technology Improvements►Software (e.g., Cadastral Fabric)►Survey equipment (e.g., GPS Total Stations)
New Surveys
