Abstract |
This dataset consists of
information about the types of geologic contacts, or boundaries, between the
mapping unit polygons of the aggregate potential layer. There are three types
of contacts: county border, geologic contact - well defined, channel scarp -
well defined. |

Title |
Meeker County Aggregate
Resource Evaluation - Boundaries between Aggregate Potential Mapping Units |
||
Abstract |
This dataset consists of
information about the types of geologic contacts, or boundaries, between the
mapping unit polygons of the aggregate potential layer. There are three types
of contacts: county border, geologic contact - well defined, channel scarp -
well defined. |
||
Purpose |
To differentiate the types
of geological contacts so that various line symbols (e.g., solid lines,
hatched lines, dashed lines) can be used to show the contacts between
polygons on a map. |

Data Quality Information |

Attribute Accuracy |
|
||
Logical Consistency |
Overshoots and undershoots
were fixed by a variety of techniques, thus the lines have been checked and
completed. |
||
Completeness |
The mapping units were
delineated by aerial photograph (at a scale of 1:40000) interpretation and
digitized onscreen, using Arcview with 1:12000 USGS DOQs and 1:24000 USGS
DRGs as the spatially registered backdrops. |

Lineage |
Color infrared and
black-and-white aerial photographs were used to delineate geological
landforms and aggregate resources. Stereoscopic pairs of color infrared
aerial photographs (NAPP, 9in x 9in at 1:40000 scale, April 1991 and April
1992) were used along with reconnaissance-level, high-altitude,
black-and-white photographs (1:80000 scale). Aerial photographs (DOQs at
1:12000) were also available digitally and used within Arcview. Aerial
photographic interpretation was completed with a glacial mapping technique
known as the landsystems approach. This technique relies on the principle
that depositional glacial landforms are composed of a predictable range of
sediments, some consisting of sorted sand and gravel and others consisting of
silts, clays, or unsorted materials. In addition to the landsystems approach,
several other general characteristics helped determine the nature of the
material, such as tonal contrasts, texture, context, shape, size, trend,
association, and patterns. These characteristics can help determine the
properties of the surface material (e.g., certain vegetation grows on well
drained soils such as sand and gravel, which on an aerial photograph has a
distinctive texture, tone, pattern, etc.). |

Information |

Entity and Attribute Overview |
The lines delineate the
polygon mapping units found in the aggregate potential layer. Note: some of
these lines, specifically the channel scarps and glacial margin, are also
found in the meekgeoln shapefile, to enable the user to portray these special
features as a continuous line symbol. |
