This thesis deals with comparsion of digital terrain models from different
sources processed in GIS for hydrological purposes. The diploma thesis is
composed from several parts. First part sis consist of characteristics related to
watershed and water flow, which are important for the understanding this work. The
thesis also describes digitial terrain model, his creation and methods for obtainig
digitial models. Then, there are described data sources from which is possible to
gain digitial models. Next chapter is dedicated to the coordinate system. The last
parts of this thesis describes drain alghorithms.
Characteristic of this area was collected on experimental watershed Modrava II
with the ESRI ArcGIS Desktop software that would mainly Spatial Analyst and
ArcHydro extensions.
The results of this diploma thesis can be concluded that the free digital terrain
model SRTM 90 is not suitable for small regions with diverse terrain structure. Thereason is a small resolution model. Other terrain models provided free of chargé are
sufficient even for small areas as the selected area of interest. Paid digitial models
can al lbe established for the area of interest as appropriate.
