ABSTRACT
Soil maps are mostly used for land evaluation, spatial planning, agricultural extension, environmental protection and other similar projects. Traditional soil maps are generally equipped to show general distribution of soils only with soil survey report. Many soil maps are now being derived using digital soil mapping providing richness in context and showing higher spatial detail than the traditional soil maps. Soil maps are now available in various digital formats, which have various applications in geosciences and environmental sciences and their use can also be extended to agriculture. In modern applications, soil maps are stored as soil resource inventories in Soil Information System (SIS) majorly containing soil geographical database. The use of aerial photographs remains an effective means of mapping soils even in the current digital era in those areas, where suitable digital imagery and data layers or the required skills, resources or support for digital mapping techniques are not available.
