Processes & Procedures for Data QA/QC GIS & DM 2008 Conference 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 GMP Green- Actually park boundary

Processes & Procedures for Data QA/QC GIS & DM 2008 Conference Having a central boundary conversion provides the opportunity to resolve shared boundaries.

Processes & Procedures for Data QA/QC GIS & DM 2008 Conference 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
