From geological to soil parent material maps - A random forest-supported analysis of geological map units and topography to support soil survey in South Tyrol

Geoderma, 2019
Parent material is an important factor of soil formation and consequently plays a dominant role in both traditional field soil survey and digital soil mapping.

Slope Class Maps from Soil Survey and Digital Elevation Models

Soil Science Society of America Journal, 1995
Abstract Special‐purpose land use maps based on slope attributes from digital elevation models (DEMs) often are produced with geographic information system technology. Field verification is lacking for accuracy and precision of computer‐generated slope class maps from 10‐ and 30‐m DEMs, a standard USDA (1:24 000) soil survey, and ...

HOW SOIL MAP UNITS AND DELINEATIONS CHANGE WITH SURVEY INTENSITY AND MAP SCALE

Canadian Journal of Soil Science, 1981
It is becoming common for soil surveys to be made of the same area at different intensities and published at different scales. The principles of cartographic generalization are discussed that control the relationships between the map units and delineations on maps made from such surveys.

Use of Soil Maps and Surveys to Interpret Soil-Landform Assemblages and Soil-Landscape Evolution

2016
Soils form in unconsolidated parent materials, which make them a key link to the geologic system that originally deposited the parent material. In young soils, i.e. those that post-date the last glaciation, parent materials can often be easily identified as to type and depositional system.

Using Published Soil Surveys in Teaching Soil Classification and Mapping¹

Agronomy Journal, 1965
SynopsisRecently published soil surveys may be used effectively as laboratory workbooks to demonstrate principles in soil genesis, classification, and survey. These surveys also provide examples which may be used to explain the interpretation of soil surveys for a number of uses.

Comparison of Surficial Geology Maps Based on Soil Survey and In Depth Geological Survey

Soil Horizons, 2015
Previous studies have suggested researchers should use Soil Survey maps to create surficial geology maps where more spatial detail about surficial geology is needed than is available from maps already produced by geologists. Despite the widespread availability of relatively detailed soil maps in the United States, few areas have a surficial geology map

Soil Survey, Classification and Mapping in Sri Lanka: Past, Present and Future

2020
Soil information is indispensable for sustainable use of the soil resource. Since its initiation in 1887, soil survey, classification and mapping activities in Sri Lanka have progressed through three successive stages. The latest soil maps of Sri Lanka developed through Sri Lanka-Canada soil resource project (1999–2004) are available at scales of 1:250,

Soil Survey, Mapping and Classification of the Uğrak Basin Soils

2014
In this study, physical, chemical and morphological properties of Uğrak Basin soils were determined and detailed soil map was prepared, by used GIS and remote sensing possibilities. Five soil series have been, described and mapped, on three different physiographic units. Field work was based on the criteria of Soil Survey Manual.

Processing map and well log data for geological and soil surveys

Mathematical Geology, 1986
Design of a system which accepts geological maps or soil maps, together with corresponding well logs and produces interpretation maps, is described. The major aim was to get a processing program that would be useful at an operational scale that avoids the use of special purpose graphics hardware. This was achieved by using segment encoding of lines and
