Frequently-anticipated questions:


What does this data set describe?

Title: onemap_prod.SDEADMIN.slandapp
Abstract:
The NCREDC in conjunction with Hobbs, Upchurch & Associates developed the digital Sewer system land applications as mapped by individual system owners as required by contract. The data collected will facilitate planning, siting and impact analysis in the 70 individual counties of North Carolina. This file enables the user to make various county-level determinations when used in conjunction with other data layers. This data contains information on sewer land applications, including: land application ID, original construction date, latest renovation, permit expiration date, and land area. Other coverages exist with sewer lines and other appurtenances.
Supplemental_Information:
The water and sewer data was collected in multiple phases. There is an associated owner and contact table (wsp2cont.dbf) for the phase 2 counties which include: Beaufort, Bertie, Bladen, Brunswick, Camden, Caswell, Chatham, Chowan, Columbus, Currituck, Dare, Duplin, Franklin, Gates, Granville, Greene, Halifax, Harnett, Hertford, Hoke, Hyde, Iredell, Jones, Lee, Lenoir, Lincoln, Martin, Montgomery, Moore, Northampton, Onslow, Pasquotank, Pender, Perquimans, Pitt, Richmond, Robeson, Sampson, Scotland, Stanly, Union, Vance, Warren, Washington and Wilson counties. 45 counties.
Phase 1 counties included: Alexander, Alleghany, Ashe, Avery, Buncombe, Burke, Caldwell, Cherokee, Clay, Cleveland, Davie, Forsyth, Graham, Haywood, Henderson, Jackson, Macon, Madison, McDowell, Mitchell, Polk, Rutherford, Stokes, Surry, Swain, Transylvania, Watauga, Wilkes, Yadkin, and Yancey counties. 30 counties.

    Hobbs, Upchurch & Associates digitized/compiled maps supplied by the participating counties. Also all tabular data was input into the CGIA supplied data standard. All heads-up digitizing was performed in AutoCAD R12-14/ArcCAD with NC DOT supplied road centerlines and hydro. Digital files were then converted into ArcView 3.0 Shape files with the appropriate dBase information. The data was completed in NAD83 Meters. Once compiled, the data was delivered to John Soles at NCREDC for review and supplied to the appropriate officials for each county for review for accurateness.

    Land application locations by county were mappjoined into one statewide GIS coverage using ARC/INFO GIS software. On-screen review of the data and attributes was performed by a GIS analyst to make sure the processing did not change the data. The draft metadata supplied by Hobbs, Upchurch and Associates was finalized for inclusion into the Corporate Geographic Database. An additional table containing source data contact and system owner information was created by HUA and has been incorporated into the data available through CGIA.

  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?

    Hobbs, Upchurch & Associates digitized locations from various maps and GPS location points. All tabular data was supplied by the owner. For more information on data sources and contacts, see the "Owner and Contact Table".

  2. How accurate are the geographic locations?

    Sewer land applications were heads-up digitized to match with the state supplied base mapping. In some cases GPS location was used. The overall threshold however is 40 feet or less. All features were Verified by both HUA engineers as well as NCREDC for accuarcy. For more information on data sources and contacts, see the "Owner and Contact Table".

  3. How accurate are the heights or depths?

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

    This data layer represents the sewer land application locations and tabular data supplied by the owner of each system. For more information on data sources and contacts, see the "Owner and Contact Table".

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

    Using ESRI's ArcCAD GIS software, the data set was built for nodal 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:
