On-the-go data collection is the basis for many applications that require spatially referenced information at a sub-field scale. A spatial or temporal offset can occur between sensor and position measurements (mostly obtained with global navigation satellite systems such as the Global Positioning System, GPS), e.g. if the antenna of the navigation system cannot be placed on top of the sensor. To correct for such an offset, we present a kinematic model that accounts for the mechanisms underlying the offset. Our model considers a sensor on a cart or sledge towed by a drawing vehicle equipped with a positioning system. The model was applied to a soil electrical conductivity survey on a 135ha site with over 100 000 measured positions. Application of the model halved a nugget effect in semivariograms, significantly (p
