%X The present work aims to compare different methods of generation of Digital Terrain Model (MDT) applied to Vitório Piassa Environmental Park, located in the municipality of Pato Branco - PR. These models were elaborated in the SAGA GIS program with planialtimetric survey data carried out by the City Hall through RTK (Real Time Kinematic) equipment, with equidistance between the 0.5m level curves in the WGS84 system. The rectangular regular ground interpolators denominated Inverse of the Distance Square were considered in the application, considering the weighted averages, the Ordinary (Global) Kriging that uses the spatial dependence between neighboring samples with minimum variance, and the Nearest Neighbor that maintains the values of Dimensions of the samples in the grid; And how unevenly the triangle Delaunay that preserved all the geomorphic features of the surface. The accuracy of the models was analyzed by the collection of control points obtained in the field with GPS (Global Position System) post-processed with Stop-and-Go method of 15 minutes per point. Differences in altitude were compared using the Inverse Distance Squares, Ordinary Kriging (Global) and Delaunay Triangulation interpolators, which presented lower Standard Deviation, with values 1.666 m, 1.667 m and 1.679 m respectively, when compared to The Nearest Neighbor who got 1,814m.
