There are many physical and chemical properties of soil that can be measured and mapped. Such maps can be very important decision-making tools in precision agriculture. However, unlike yield maps and crop scouting maps, all other maps show a lower degree of reliability in terms of decision utility. Soil compaction is the most representative feature of the production plot from the domain of physical and chemical soil properties. This paper first presents an experiment designed to measure soil compaction, and then a mapping of the results in a commercial software. The test field with an area of one hectare was reduced to a control limit of 60 meters in width and 120 meters in length to ensure the uniformity of speed and other parameters. The resolution of the draft force measurement as an indicator of soil compaction was 50 Hz. This resulted in the existence of missing data on the draft force map itself, because several draft force values were related to one spatial coordinate manifested as longitude and latitude. The paper further shows the procedure of data smoothing and generation of complete maps without missing spatial data.
