Description:

Abstract:

These digital maps are a reformulation of previously published maps, primarily maps of states. The reformulation gives all the maps the same structure and format, allowing them to be combined into regional maps. The associated data tables have information about age and lithology of the map units, also in a standard format.

Purpose:

Provide digital maps and databases that, because of their common structure and format, allow creation of regional maps that depict age and lithology of map units.

Supplemental_Information:

The data is provided in decimal degrees and in Lambert Conformal Conic projection. The data is provided in both coverage and shapefile format, and includes supplemental attribute tables. No attempt was made to reconcile differences in mapping across state boundaries.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Map unit designations follow original compilation faithfully. Regional designations were added to map units. Additional information about age and lithology was obtained from the paper map legend and geologic literature.

Logical_Consistency_Report:

All internal polygons were checked for closure. Overshoots and undershoots have been deleted or corrected as appropriate.

Completeness_Report:

The dataset contains all the map units and faults that were portrayed on the original printed map. Bodies of water are classified as water, and geologic units underlying them are not portrayed.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The geologic map was digitized from compilations ranging in scale from 1:100,000 to 1:1,000,000, and is an accurate representation of the source maps. It is intended to be used at scales equal to or smaller than 1:500,000. Display at significantly larger scales may produce error in location of contacts or faults relative to features contained in other data sets. The state boundary arcs are based on the 1:100,000 scale USGS topographic map series digital line graphs.

Source_Citation_Abbreviation: US001

Source_Contribution: Provided linework for state boundaries

Process_Step:

Process_Description: Dataset copied from the CD-ROM.

Process_Date: 2002

Process_Step:

Process_Description:

Adjusted the perimeter of the coverage to match a reference dataset of state boundaries derived from 1:100,000 scale digital line graphs. This allows the map to be used together with adjoining state maps referenced to the same boundary data. The state boundaries have a source of US001 in the AAT.

Process_Date: 2004

Process_Step:

Process_Description:

Created 13 new polygons to conform to the paper map. These polygons have a SOURCE of UT901 in the PAT.

Process_Date: 2006

Process_Step:

Process_Description:

One polygon was untagged in original digital coverage; it was tagged to conform to the Box Elder 1:250,000 map. This polygon has a SOURCE of UT902 in the PAT.

Process_Date: 2006

Process_Step:

Process_Description:

Labels for 35 polygons were changed to conform to the paper map. These polygons have a SOURCE of UT903 in the PAT

Process_Date: 2006

Process_Step:

Process_Description:

One polygon label was changed to conform to the adjacent Nevada state map. This polygon has a SOURCE of UT904 in the PAT.

Process_Date: 2006

Process_Step:

Process_Description:

One polygon label was changed to conform to the Escalante1:250,000 map. This polygon has a SOURCE of UT905 in the PAT.

Process_Date: 2006

Process_Step:

Process_Description:

The appropriate arcs were recoded as state and international boundaries.These have a SOURCE of US001 in the AAT.

Process_Date: 2006

Process_Step:

Process_Description:

To prepare a uniform AAT file, the following items were added: arc-code, arc-para1, and arc-para2. The last two are not used. Arc-code was populated, using the information in the original item, and inspection of the printed map. Then the original items in the AAT were deleted.

Process_Date: 2006

Process_Step:

Process_Description:

To prepare a uniform PAT file, the following items were added: ORIG_LABEL, SGMC_LABEL, UNIT_LINK, SOURCE, UNIT_AGE, ROCKTYPE1, and ROCKTYPE2. New unit designations for SGMC_LABEL were developed by Steve Ludington based on the key to Utah regions on the explanation sheet of the paper map. UNIT_LINK was populated with information in the accompanying attribute table UTunits, UNIT_AGE was populated with information in the accompanying attribute table CAage, and ROCKTYPE1 and ROCKTYPE2 were populated by Constance J. Nutt.

Process_Date: 2002-6

Process_Step:

Process_Description:

Because there is no list of map units for the Utah map, Steve Ludington created original map units based on the explanation sheet of the paper map. At the same time, he assigned polygons to regions where information was available to distinguish between age and lithologic information in different regions.

Process_Date: 2006

Process_Step:

Process_Description:

The labels of two polygons were changed to conform to the Cortez 1:250,000 map.These polygons have a SOURCE of UT906 in the PAT.

Process_Date: 2006

Process_Step:

Process_Description:

Twenty-four arcs were added to split polygons and create new ones to conform to the paper map. These arcs have a SOURCE of UT801 in the AAT.

Process_Date: 2006

Process_Step:

Process_Description:

470 arcs were changed to ARC-CODE = 8 because the identity of the polygons on both sides of the arc were the same. These arcs have a SOURCE of UT802 in the AAT.

Process_Date: 2006

Process_Step:

Process_Description:

295 arcs were given ARC-CODE = 8 because they were tagged as "Gilsonite veins" on the original coverage, and there is no corresponding arc code. These arcs have a SOURCE of UT803 in the AAT.
