Why was the data set created?

This data set 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)

   EPA Landfill Methane Outreach Program, 20041021, LMOP (Landfill Methane Outreach Program) Landfill Sites: EPA Landfill Methane Outreach Program, Washington, DC.

   Other_Citation_Details: Data is updated as needed

   Type_of_Source_Media: Microsoft Excel

   Source_Contribution:

   Locations of LMOP (Landfill Methane Outreach Program) Landfill Sites

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

   Date: Nov-2004 (process 1 of 4)

   Latitude and Longitude coordinates of landfill points were derived from Excel spreadsheet and used to generate ARC/INFO points coverage. For entries that had no latitude/longitude information, physical address was derived from the Excel spreadsheet and used to generate the locations of these landfills using www.mapquest.com. Entries that had no latitude/longitude coordinates or physical address were located using CGIA Solid Waste Facilities data. Point locations were verified using aerial photography images in ARC/EDIT.

   Date: 2004 (process 2 of 4)

   The Energy Center at the Appalachian Regional Development Institute, Appalachian State University, analyzed a file of manufacturer locations in North Carolina from a commercial database created by the Harris Company, and created point locations for companies along with values for natural gas usage based on the 3-digit NAICS industry survey of energy usage in 1998. CGIA created a point layer from the file, spatially joined the company points to 10-mile landfill buffers, summed average annual employment within buffers, and joined the tabular results to the landfill points.

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?

   The EPA Landfill Methane Outreach Program presented the LMOP (Landfill Methane Outreach Program) Landfill Sites to NC CGIA in an Excel file. The latitude/longitude coordinates were used to generate an ARC/INFO points coverage and the points were given attributes also supplied by EPA Landfill Methane Outreach Program. Where latitude/longitude coordinates were not provided, the physical address was used. Where physical address was also not provided, CGIA Solid Waste Facilities data was used to locate these landfills. Aerial photography images were used to verify point locations.

2. How accurate are the geographic locations?

   The LMOP (Landfill Methane Outreach Program) Landfill Sites were generated from latitude/longitude coordinates, physical address, or CGIA Solid Waste Facilities data. Sites were verified using aerial photography images.

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 LMOP (Landfill Methane Outreach Program) Landfill Sites in North Carolina as identified by EPA Landfill Methane Outreach Program.

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

   Using ESRI's ARC/INFO GIS software, the dataset was built for points 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 LMOP (Landfill Methane Outreach Program) Landfill Sites 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. While efforts have been made to ensure that these data are accurate and reliable within the state of the art, CGIA cannot assume liability for any damages or misrepresentation caused by any inaccuracies in the data or as a result of changes to the data caused by system transfers.
