1 Processes & Procedures for Data QA/QC GIS & DM 2008 Conference How Accurate is your Boundary… ask Lands Jean Olson Richard Easterbrook Jeannie Whitler

2 Processes & Procedures for Data QA/QC GIS & DM 2008 Conference The Land Resources Division (LRD) is responsible for the Official Boundary, Legislative Maps, Acreage Calculations and Land Status Maps for all NPS park units. May 4 th 2004 Director of the National Park Service, Fran Mainella

3 ► Quality Assurance: Activities designed to ensure the development and maintenance process is adequate to ensure a system will meet its needs. Processes & Procedures for Data QA/QC GIS & DM 2008 Conference  Land Acquisition Procedures (LAPS) Chapter 5 - Land Status Mapping Standards Land Acquisition Procedures (LAPS) Chapter 5 - Land Status Mapping Standards Land Acquisition Procedures (LAPS) Chapter 5 - Land Status Mapping Standards ► Data Sources (e.g., BLM, USGS, NPS, State & Local Gov.) Data Sources (e.g., BLM, USGS, NPS, State & Local Gov.) Data Sources (e.g., BLM, USGS, NPS, State & Local Gov.) ► Computer Software Platforms Computer Software Platforms Computer Software Platforms ► Map Content (e.g., boundary, tracts, drawing number) Map Content (e.g., boundary, tracts, drawing number) Map Content (e.g., boundary, tracts, drawing number) ► CAD Drawing Requirements (e.g. layer organization, topology) CAD Drawing Requirements (e.g. layer organization, topology) CAD Drawing Requirements (e.g. layer organization, topology)  Digital Map Conversion Standard Operating Procedures (SOP) Digital Map Conversion Standard Operating Procedures (SOP) Digital Map Conversion Standard Operating Procedures (SOP)  Legislative Map Guidelines & Template – Congressional & Legislative Affairs Legislative Map Guidelines & Template – Congressional & Legislative Affairs Legislative Map Guidelines & Template – Congressional & Legislative Affairs  Metadata Template & FGDC Guidelines Metadata Template & FGDC Guidelines Metadata Template & FGDC Guidelines ► Land Status Map (Segment Map) Templates (e.g., Symbology) Land Status Map (Segment Map) Templates (e.g., Symbology) Land Status Map (Segment Map) Templates (e.g., Symbology) ► Distribution of Final Product (TIC, WASO, GIS Coord., Superintendents )

4 Processes & Procedures for Data QA/QC GIS & DM 2008 Conference ► Quality Control: Quality Control: Quality Control: Activities designed to evaluate a developed work product. Activities designed to evaluate a developed work product.  Database Integrity Database Integrity Database Integrity ► Check all attributes from the Master Deed List (MDL) to ensure they match the GIS file and final segment map. Check all attributes from the Master Deed List (MDL) to ensure they match the GIS file and final segment map. Check all attributes from the Master Deed List (MDL) to ensure they match the GIS file and final segment map.  Tract Integrity Tract Integrity Tract Integrity ► Check coordinate geometry against deeds, legal descriptions, legislation/legislative maps, survey and historic maps. Check coordinate geometry against deeds, legal descriptions, legislation/legislative maps, survey and historic maps. Check coordinate geometry against deeds, legal descriptions, legislation/legislative maps, survey and historic maps.  Spatial Integrity Spatial Integrity Spatial Integrity ► Check control sources (e.g. monumentation), surveys, ortho- photography, topographic maps and misc. GIS data. Check control sources (e.g. monumentation), surveys, ortho- photography, topographic maps and misc. GIS data. Check control sources (e.g. monumentation), surveys, ortho- photography, topographic maps and misc. GIS data.  Attribute Integrity ► Verify proper layering and symbology and check attributes with ownership database.  2 nd Review Process 2 nd Review Process 2 nd Review Process ► All above checks are performed by an additional Lands cartographer. All above checks are performed by an additional Lands cartographer. All above checks are performed by an additional Lands cartographer. ► Review the final shapefile in ArcGIS for spatial and attribute integrity. Check projection. Review the final shapefile in ArcGIS for spatial and attribute integrity. Check projection. Review the final shapefile in ArcGIS for spatial and attribute integrity. Check projection. ► Build and verify topology. Build and verify topology. Build and verify topology.

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

7 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

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

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

10 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
