Presentation Form vector digital data

Abstract ESRI ArcView shapefile depicting New Mexico coal mines permitted under the Surface Mining Control and Reclamation Act of 1977 (SMCRA), by either the NM Mining & Minerals Division (MMD), or by the federal DOI Office of Surface Mining, Reclamation & Enforcement, as of October 2005. The permit boundaries of the mines are displayed as polygons; these boundaries were typically derived from source AutoCAD drawing (.dwg) files submitted to as part of the permitting process, and are known to contain some inaccuracies.

Purpose The data is intended for general depiction of New Mexico coal mine permit boundaries, and not for highly detailed analysis requiring accurate locations.

Access Constraints This dataset is freely available to the public, with the constraints that the accuracy limitations are understood, and the metadata are included whenever this dataset is distributed.

Use Constraints This dataset may be used to depict the general overall location of New Mexico permit coal mine boundaries, provided the user does not state or imply that the dataset is highly accurate, and furthermore, provided the user correctly attributes the source of the data to be the MMD.

Data Quality Information

Attribute Accuracy Report

Report The primary attribute of interest to the typical user would be the "mine name". The mine name given is consistent with that which is used by the mine operator, the general public, and MMD. Attributes providing areal extent, such as "Area_m2", "Hectares", and "Acres", should be within reasonable limits. "PermitNum" - the Permit Number assigned by the regulatory authority having jurisdiction - is accurate as of the publication date, but is subject to periodic change, as would be "Operator". "Jurisdict" should be fine. "Status" is accruate, but can change as market conditions and other factors may influence it.

Horizontal Positional Accuracy Report

Report The permit boundaries indicated within this dataset are derived from a range of sources: different mine operators, at different time periods, using different technologies. Some are delivered as paper maps with estimated locations of bondary points taken from a USGS topo map. Some may be "surveyed in" and delivered as digital information as part of an AutoCAD drawing. Due to the wide range of possibilities, it is very difficult to determine an accuracy value, yet alone feel comfortable in providing one that covers all the possibiliities. We hope to work with the various mines to provide more detailed accuracy information, and more accurate positions, in the future.

Quantitative Horizontal Positional Accuracy Assessment

Horizontal Positional Accuracy Value 100
Horizontal Positional Accuracy Explanation From comparisions to other sources, such as orthophotos, the positions of the permit boundaries should be accurate to within 100 meters. MMD itself does not rely on this dataset to be any more accurate than that value, and the user should not either. In instances where a "permit boundary" question might have legal import, MMD would hire a surveyor to ascertain the position to a high degree.

Logical Consistency Report To the best of our knowledge, the dataset contains no broken or unclosed polygons, no fractional entities, etc. All polygons are closed and complete. Both Autodesk AutoCAD Map 3D 2005 and ESRI ArcGIS 9.0 were used to produce a clean dataset.

Completeness Report The dataset is complete in that it reflects the domain of "permitted coal mine boundaries" as of the publication date. No more, no less.

Process Step

Process Description 4a) AutoCAD drawing is reviewed, and layer containing permit boundary is isolated ("layiso") and inspected for suitability, correctness, etc. Edited, and converted to polygon if necessary. 4b) Paper map is reviewed, placed on digitizer, whereupon AutoCAD is used to enter digitized location of permit boundary. Boundary is reviewed for suitability, correctness, etc.
