  2. How were the data generated, processed, and modified?

    Date: 02-Jul-2003 (process 1 of 3)
    CGIA used a road network from GDT, Inc. with ArcView GIS to geocode the addresses. This process matched potential emergency shelters with a point on the road network. Point locations are approximate, based on an interpolation of street numbers along street segments. The resulting file was checked to determine which addresses did not match. These locations were then added to the coverage interactively, using GDT roads, Digital Orthophoto Quarter Quadrangels as backcovers. Many of these point locations are coincident with the center of buildings on digital imagery or along driveways and may be more accurate than points located using the first method. Geographic layers from the NC Corporate Geographic Database to determine potential emergency shelter locations.

  3. What similar or related data should the user be aware of?

    CGIA, NC, 2003, Shelters in North Carolina.


How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    The attributes were loaded into the GIS from data supplied by the NC Department of Public Instruction, US Army Corps of Engineers, NC Community College System, Federal Emergency Management Agency (HAZUS 99), and the NC State Property Office. The values in this dataset are deemed to be reliable.

  2. How accurate are the geographic locations?

    The majority of potential emergency shelter locations were generated using geocoding in ArcView. The point generated in the processing would be snapped to the road identified in the address field. Therefore, point locations are coincident with the GDT roads data.

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    The data represents those potential emergency shelters which were either address matched using ArcView geocoding or matched manually using the best available techniques. This data set does not contain all the potential emergency shelter locations in North Carolina, as other types of buildings may be appropriate for a specific event.

  5. How consistent are the relationships among the observations, including topology?

    Using ESRI's ARC/INFO GIS software, the dataset was built for point topology using the "build" command. Topology has not been edited since the last build or clean.


How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?

Access_Constraints: None
Use_Constraints:
Acknowledgement of products derived from this data set should cite the following: The source of the potential emergency shelter data is the North Carolina Corporate Geographic Database. Earlier versions of this dataset may exist. The user must be sure to use the appropriate data set for the time period of interest.
