POSSIBILITIES FOR CARTOGRAPHY OF THE PROVINCE OF ENTRE RÍOS USING THE GAUSS-KRÜGER ZONE EXTENSION

Abstract

This study focuses on the need to know the maximum scale at which it is possible to work with only a single Gauss Krüger zone within the Province of Entre Ríos, assuming a low admissible error level. With the creation of the Infrastructure of Spatial Data in Entre Ríos (IDEER) and the participation of different institutions in the region, it is necessary to arrive at agreements on the protection systems to be used in the presentation of the cartography generated by institutions. In the method, the Gauss-Krüger mathematical model is applied to obtain the scale factors based on the geodesic coordinates and to analyse the maximum distortions produced in the provincial territory. The results indicated 47cm/ km of maximum distortion inherent in the cartographic projection  within the provincial territory. This permits scales that reach up to 1:5.000 for the generation of cartography with images with high spatial definition.
