Three-dimensional interpolation of soil data: fertility and pedomorphological features in southern Brazil Rev. Bras. Ciênc. Solo
Piedade,Tales de Campos; Melo,Vander de Freitas; Souza,Luiz Cláudio de Paula; Dieckow,Jeferson.
The graphical representation of spatial soil properties in a digital environment is complex because it requires a conversion of data collected in a discrete form onto a continuous surface. The objective of this study was to apply three-dimension techniques of interpolation and visualization on soil texture and fertility properties and establish relationships with pedogenetic factors and processes in a slope area. The GRASS Geographic Information System was used to generate three-dimensional models and ParaView software to visualize soil volumes. Samples of the A, AB, BA, and B horizons were collected in a regular 122-point grid in an area of 13 ha, in Pinhais, PR, in southern Brazil. Geoprocessing and graphic computing techniques were effective in...
