Analysis of continuous fields (coverages), widely known in GIS technology, has not yet been used to significant degree in the Spatial Information System created for the needs of the State Forests. Also, there are not many scientific and conceptual works in the area of continuous fields modeling for the needs of forestry. In the paper, the following subjects are presented: 1) two potential areas for application of continuous models in forest districts, i.e. digital terrain model (DTM) and soil maps when discussing the method of their creation and use, 2) growing possibilities of using continuous fields models, particularly DTM, in GIS technology to make multi-variant analyses for the needs of the State Forests Administration, 3) prospects for development of large scale DTM in Poland, including for the needs of forestry. Conditions necessary for successful application of continuous fields models in forest districts were defined as follows: 1) accumulation of precise source data, 2) providing applications for appropriate analyses and 3D visualisation, 3) staff training.
