Why was the data set created?

This data was created to assist governmental agencies and others in making resource management decisions through use of a Geographic Information System (GIS).


How was the data set created?

  1. From what previous works were the data drawn?

    None (source 1 of 1)
    State Library of North Carolina, 20030325, Public Libraries: State Library of North Carolina, Raleigh, North Carolina.

    Other_Citation_Details: Generated at NCCGIA
    Type_of_Source_Media: Paper
    Source_Contribution: Public Libraries

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

    Date: 25-Mar-2003 (process 1 of 2)
    Point locations were generated using geocoding in Arcview from the public libraries address list provided by the State Library of North Carolina on 3/20/03. Points that could not be generated using geocoding were interactively added in arcedit using mapquest.com. This digital file is updated as changes occur.

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


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

  1. How well have the observations been checked?

    Point locations were generated using geocoding in Arcview from the public libraries address list provided by the State Library of North Carolina on 3/20/03. Points that could not be generated using geocoding were interactively added in arcedit using mapquest.com. This digital file is updated as changes occur.

  2. How accurate are the geographic locations?

    The majority of Public Libraries 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?

    These data represent the locations of Public Libraries in North Carolina as listed by the State Library of North Carolina. The locations were either address-matched using ArcView geocoding or matched manually using mapquest.com.

  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 Public Libraries data is the North Carolina Corporate Geographic Database. Earlier versions of this data set may exist.
