Title |
Renville County Aggregate Resource Evaluation - Geology 'Line' Features |
|||
Abstract |
This dataset consists of information about the types of landforms and features that are best represented on a map by a line (or arc). These landforms include channel scarps in Renville County. |
|||
Purpose |
To represent small, linear, surficial geologic landforms and features on a map as lines, because they are too small to be represented by a polygon. |

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.). |

Entity and Attribute
Information |
|||
Entity and Attribute Overview |
The lines represent geologic landforms that are too small to be mapped as polygons. Note: some of these lines are also found in the renvagpln shapefile, because they form the boundary between two polygon mapping units. |
