Accuracy of digital terrain model and its application in forestry
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2007 Digital terrain model (DTM) is considered as an important geospatial data layer. At the present in the Czech Republic, digital contour data sources are often used for constructing regular raster DTM; the initial process requires interpolation between the
