Land cover maps are tools that provide vital information about the Earth's land use and cover patterns. They aid policy development, urban planning, and forest and agricultural monitoring. [1] [2] The systematic mapping of land cover patterns, including change detection, often follows two main approaches: Field survey
Land use capability maps are maps created to represent the potential uses of a "unit" of land. They are measured using various indicators, although the most common are five physical factors ( rock type , soil type , slope, erosion degree and type, and vegetation).
An optimum figure for topsoil in the UK is a C:N ratio of less than 20:1. ... erosion through the use of cover crops in order to build organic matter in the soil. The ...
The most current soil survey data is made available for high end GIS users such as professional consulting companies and universities. Typical information in a published county soil survey includes the following: [1] a brief overview on how to use the survey; a general soil map for comparing the sustainability of large sections of the county
Such maps are typically richer in context and show higher spatial detail, yet are not necessarily more accurate than traditional soil maps. Soil maps produced using (geo)statistical technique can also include an estimate of the model uncertainty. [3] An example of a traditional soil map showing soil mapping units, described soil profiles and ...
You can find the Metadata for 1,312 European maps. This is part of the global EuDASM project making available more than 6,000 Maps from 142 countries around the World. EuDASM transferred paper-based soil maps into a digital format with the maximum possible resolution and to ensure their preservation and easy disclosure.
Digital soil mapping tries to overcome some of the drawbacks of the traditional soil maps that are often only focused on delineating soil-classes i.e. soil types. [5] Such traditional soil maps: do not provide information for modeling the dynamics of soil conditions and; are inflexible to quantitative studies on the functionality of soils.
Soil texture triangle showing the USDA classification system based on grain size Map of global soil regions from the USDA. For soil resources, experience has shown that a natural system approach to classification, i.e. grouping soils by their intrinsic property (soil morphology), behaviour, or genesis, results in classes that can be interpreted for many diverse uses.
