AbstractTo investigate soil physical conditions affected by soil compaction or tillage, a computer controlled cone resistance measuring system and visualization software for generating cone resistance distribution maps were developed. A cone resistance measuring system was developed so that the coordinates of the measuring point were chosen at any location in a 1.5 × 2 m horizontal x−y plane. Then, using, a series of cone resistances with x, y, z coordinates was measured. A portable computer was selected to measure and acquire the series of cone resistances. This computer was used to set the location of the cone, to operate a strain amplifier for measuring cone resistance and to measure the location of data. The visualization software generates two- and three-dimensional maps. x−z, y−z and x−y cross section are generated in two-dimensional maps. Plane and view point may be selected from a three-dimensional map. Using this system, cone resistance of 1.5 m with × 2.0 m length × 0.6 m depth in several fields was measured. Cone resistance distribution maps of two and three dimensions were generated by the visualization software. It was concluded that two- and three-dimensional distribution maps gave us information that we could not obtain from a map of one cross section.
