Describe climate and soil classifications, using raw data and thematic maps - Essay Example

The main objective of this study is to evaluate the usefulness of landsite, thematic mapper to help in soil classification in Johannesburg in South Africa. Climate system is based on the location of hot and cold air-mass region and the atmospheric circulation created by trade winds in wester-lies. South Africa soil classification is based on the location and the kind of climate being experienced and the location of the place. Thematic mapper (TM) scene from the Johannesburg, in South Africa, mapped with the soil taxonomy system becomes the preferred city of attention.

In that case four sensing approaches were created to determine the best method to identify soil mapping-units. They were named as simple, technical, scaled and complex approaches. The agreement to use the TM data was tested using the matrix approach in a supervised classification, where spectral signatures were selected by separability analysis and applying the transformed divergence technique. The table fully describes the entire approaches that were utilized by the climatologists to obtain their data.

The statistical accuracy and the data reduction of a thirty years span makes technical approach of obtaining data the most appropriate in this situation. Monitoring and assessing the state of earth and its climate is the key requirement to the global change research. Managing climate and vegetation, requires a lot of study that is much complex than that of soil classification. The classification and mapping of vegetation is a time consuming process and it takes scientist and experts for accurate data to be relied upon.

The use of Koppen climate classification system is the most widely used for classifying world climate in both a simple and complicated manor. Classification system use today was developed from the one introduced by the Russian-German climatologist Koppen in 1900. He divided Earth’s climatic regions to generally coincide with world pattern of
