Abstract: This paper presents main conditions in quality of input data, spatial model optimization and result validation within soil survey in semidetail scale (1:50 000). Position accuracy was determined using reference measurement. Condition of spatial dependence using theory of regionalized variable was applied for interpolation of selected soil parameters. Not every parameter demonstrates optimal condition of spatial dependence (low sampling distance, discrete transition, time dynamic, etc.) Linear regression between measured and estimated values represent powerful tool for validation of method estimation. There are different results in existing tools in spatial interpolation of reference material using identical conditions.
