Digital Mapping
-
Digital mapping uses geographic information systems (GIS) to increase the accuracy of land maps. GIS helps take into consideration topography, vegetation and soil types to better determine soil and land use relationships.
Pedometrics
-
Pedometrics uses qualitative methods for mapping soil. According to the University of Twente in the Netherlands, pedometrics makes soil survey, classification and land evaluation as factual as possible.
-
Geo-statistics
-
Geo-statistics uses statistics to explore and model soils through spatial data for soil mapping. It implies the use of mathematical calculations of GIS data in interpreting geological observations.
Sensors
-
Sensors are a common approach in surveying soil. It is a technological technique using infrared spectrometry to scan and map soil.
Laboratory Methods
-
Using laboratory methods to analyze soils for mapping is useful in determining fertility and soil profiles. Changes in soil chemistry over time can also provide information on relationships between land use and soil.
