NC GIS Conference

2. GIS Framework Data Imagery Parcels Roads Elevation Address Points
Application Examples
Imagery
Parcels
Roads
Elevation
Address Points
Streams
Property appraisal
Public works
Schools / Community Assets
Emergency Preparedness
First Response
Site Suitability
Foundation for mapping and analysis: Where? What? Distance?
Value in state, local, private business process
Return on investment, e.g., economic development, public safety…

3. Putting GIS Framework Data to Work
Economic Development
Scenario: Industry seeking to
develop site in NC
Criteria:
Vacant land at least 20 acres
Near US Highway interchange
Polk or Rutherford County
Supporting Data:
Imagery
Transportation
Property boundaries
Address points
Elevation

4. Where are they? Show potential sites that meet developer criteria
Potential sites meet criteria on
both sides of county boundary
With standardized framework
data, results can be queried
and viewed at one time

5. Without statewide standardized data:
3 single- county parcel map viewers
With a variety of field names for parcel size, parcel value, ownership, etc.

6. What does it look like? Display the imagery Farmland? Forest?
Adjacent parcels?
Select an area of interest for more detail (yellow

7. What is the site like? Add elevation contours
Add address points (orange) for
additional reference

8. Value of Statewide Datasets
Consistency
Efficiency
Trust
Capability
Consistency – data is standardized across counties and regions
Efficiency – analyze data can be analyzed comprehensively
Trust – data is documented from state and local government sources
Capability - do more in less time

9. The statewide program acquires orthoimagery for one-fourth of the state each year. Since the statewide collection in 2010, three of four regions are complete and published on NC OneMap, and the fourth is being flown this winter. The NC 911 Board has funded the program.

10. The NC Parcel Project is producing copies of parcel boundaries published by counties with standardized data fields. Data are published in a Web Feature Service from the Carbon Project and published as map and feature services by NC OneMap. 57 counties have completed transformations to date.

11. Statewide Data Value! Local government data are vital
Collaboration in business solutions more common
Investment in GIS brings returns
GIS widely used, valuable, focused on business applications
Local government data are vital for local purposes and as sources for statewide, standardized datasets
Collaboration in business solutions
Investment in GIS brings returns
