What is Mukey?
The mapunit key (mukey) field needs to be in the spatial data attribute table in order to use the Soil Data Viewer ArcGIS extension. It is also very useful when working with spatial and tabular data that contains more than one subset survey area. The mukey is unique nationally.
What is Statsgo?
The Digital General Soil Map of the United States or STATSGO2 is a broad-based inventory of soils and non-soil areas that occur in a repeatable pattern on the landscape and that can be cartographically shown at the scale mapped of 1:250,000 in the continental U.S., Hawaii, Puerto Rico, and the Virgin Islands and 1: …
What is the projection of the NRCS soil data?
The measurement tool provides a more accurate distance measurement than possible using the “flat earth” Web Mercator projection: the Web Mercator coordinates at the measurement points are converted to “WGS 84” geographic coordinates and the geodesic distance between these points is then calculated.
How do I use Ssurgo data in ArcMap?
Relates
- Step 1: Register the SSURGO tables to the Geodatabase. In Arc Catalog, open the SSURGO template.
- Launch ArcMap.
- Minimize ArcCatalog.
- Add the tables to ArcMap. Add the spatial layer,
- Set up the Relates. Right click on the spatial layer and select Join and Relates/Relate.
- Step 4: Using the Relates.
What is tabular and spatial soil?
Soil data consists of spatial and tabular data. Spatial data consist of soil lines and symbols. Tabular data contain rows and columns of information about specific types of soil.
What is TIFF soil?
The Tiff series consists of very deep, well drained, moderately permeable soils that formed clayey residuum on uplands. These soils are on nearly level to moderately steep areas that have been truncated by mining operations. Slopes range from 1 to 20 percent.
What is my soil type?
Use the U.S.D.A Natural Resources Conservation Service’s Soil Textural Triangle to determine the soil type by drawing lines to represent the percentages of the three components. The point where they converge is the soil texture; in this case, between a sandy loam and a sandy clay loam.
What is soil mapping unit?
A soil map unit is a collection of areas that are relatively homogeneous in soil constitution or miscellaneous areas that constitute different soil components or both. From: Reference Module in Earth Systems and Environmental Sciences, 2021.
What are soil mapping methods?
Soil mapping involves locating and identifying the different soils that occur, collecting information about their location, nature, properties and potential use, and recording this information on maps and in supporting documents to show the spatial distribution of every soil.
What is tabular soil?
A tabular database is created from spatial data by generating descriptive statistics for each data layer within each soil premap delineation.
What is Alfisols soil?
Alfisols are moderately leached soils that have relatively high native fertility. These soils have mainly formed under forest and have a subsurface horizon in which clays have accumulated. Alfisols are primarily found in temperate humid and subhumid regions of the world.
What are the 4 soil types?
OSHA classifies soils into four categories: Solid Rock, Type A, Type B, and Type C. Solid Rock is the most stable, and Type C soil is the least stable. Soils are typed not only by how cohesive they are, but also by the conditions in which they are found.
Why is soil mapping important?
Soil mapping is very important for the correct implementation of sustainable land use management. In recent decades, soil mapping methods and data availability have increased exponentially, improving the quality of the maps produced.
Who uses Soilmaps?
The soil survey has maps with soil boundaries and photos, descriptions, and tables of soil properties and features. Soil surveys are used by farmers, real estate agents, land use planners, engineers and others who desire information about the soil resource.
What are the types of soil map?
It is important to distinguish between the following types of soil maps:
- hand-drawn soil polygon maps representing distribution of soil types;
- simulated or predicted 2D/3D soil property maps (primary or secondary soil properties);
- simulated or predicted (2D) soil-class maps;
