Abstract:
Digitized vector data of BLM designated Areas of Critical
Environmental Concern (ACEC) in Arizona.
Digitized from 1:24,000 scale manuscripts prepared by Field
Office Specialists or digitized on-screen and edited at
1:24:000 scale or larger by GIS specialists. |

Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.
Digitized vector data of BLM designated Areas of Critical Environmental Concern (ACEC) in Arizona. Digitized from 1:24,000 scale manuscripts prepared by Field Office Specialists or digitized on-screen and edited at 1:24:000 scale or larger by GIS specialists.
Developed to take advantage of GIS software for data analysis and for producing hard copy maps.

Attribute accuracy is tested by manually comparing hard copy plots of the digital data with source materials or by interactively querying and verifying on the screen.
The data has been checked to make sure that all intended polygons are closed, that there are no unintended undershoots, overshoots or dangles and that there is only only label point per polygon. This does not preclude the presence of one or more of these errors.
This coverage is in draft format. Verification by the appropriate BLM Field Office is needed.
Approximately + or - 40 feet. Test by visual comparison of hard copy check plots against source material and/ or verfying the location of the data on screen relative to other data layers in the same geographic area.
None.
Vector data representing BLM designated Areas of Critical Environmental Concern boundaries.
Data were compiled on 1:24000 scale USGS paper quads and digitized from those quads. Some of the original ArcInfo coverages were converted to shapefiles and edited in ArcView while others were edited in ArcEdit. Shapefiles were converted back coverages and Individual files were then merged into a single statewide coverage. Data was checked on screen against other data layers in the same geographic area.

This value refers to the natural, manmade, or mapping feature that represents the NCA boundary. This value is recorded on each arc. This field is used when coincident lines are part of the NCA boundary. For example, if a portion of the NCA boundary follows a stream, the NCA_DEF_FEATURE would be stream, if following a contour line, the NCA_DEF_FEATURE would be contour, etc. Entries for this field should be lowercase. If the NCA_DEF_FEATURE was not used when digitizing or updating this theme this field should be blank. (See Appendix C for the official list of defining features.) This value should be in lowercase.
This value refers to the actual source of the defining feature. It is the digital map source of the original arc that makes up the NCA boundary. For example, if a portion of the boundary is a contour line the NCA_DEF_FEATURE would be contour and the NCA_COORD_SOURCE would be 24K Digital Elevation Model (DEM). If other coverage's are used then the NCA_COORD_SOURCE would be the coverage name. For example, 100K DLG or 24K DLG.
This value refers to the official name of the National Conservation Area. It may contain spaces, plus a combination of upper and lowercase alpha characters. For example, King Range National Conservation Area. Inholding polygons should be labeled "inholding".
This value refers to the serialized case file number for each National Conservation Area. This field should be in uppercase. For example, CA035582. Inholding polygons should not be given a casefile number.
San Pedro RNCA
Gila Box RNCA
Las Cienegas NCA
This value refers to the official name of the National Conservation Area. It may contain spaces, plus a combination of upper and lowercase alpha characters. For example, King Range National Conservation Area. Inholding polygons should be labeled "inholding".
Gila Box Riparian National Conservation Area
San Pedro Riparian National Conservation Area
Las Cienegas National Conservation Area
This value refers to the administrative State for the National Conservation Area. This field should be the two digit uppercase code for the State. For example, CA.
Arizona
Number of acres in each NCA polygon.
