DALMOLIN, Ricardo Simão Diniz  y  TEN CATEN, Alexandre. Digital mapping: new approach on soil survey. Investig. Agrar. [online]. 2015, vol.17, n.2, pp.77-86. ISSN 2305-0683.

Increasingly intensive use of soil and its disorganized occupancy result in its degradation. There is a lack of more detailed information on soils and on soil surveys. Soil mappings are key for land sustainable management because they provide basic information about this natural resource and its distribution on the landscape. The production of highly detailed soil class and attribute maps, will only be possible using geotechnologies in combination with field data. The objective of this review was to emphasize the importance of soil surveys within a new paradigm, defined as Digital Soil Mapping (DSM). DSM requires: i)  the use of data from field sampling and analytical results from laboratories, including existing as well as newly collected data ii) the process of inference and of spacing includes a proposition of mathematical and statistical models based on soil observation, environmental covariates and other scorpan factors iii)  results should be presented as soil spatial system format with continuous and/or discrete data, added to the uncertainty of this information, which could be updated whenever new observations become available. The application of DSM will make it possible for soil spatial information, attributes and classes to be generated and be readily available in digital format with its associated uncertainty. Among the challenges for further implementation of several strategies available in DSM, the training of future generations of soil scientists should be a priority.
