Elaboration of a local projection system in mainland ecuador for the generation of detailed cartography
Abstract:
Several countries use the UTM projection system due to the advantages it has in cartographic representation for scales smaller than 1:25,000, because these scales absorb deformations. Currently this projective system is used together with classical topographic techniques and GNSS technology to generate detailed cartography, causing in-compatibility between measurements on the field with respect to their corresponding ones on the map. For this reason, it is proposed to create a Local Cartographic Projection System in continental Ecuador for 1:500 and 1:1,000 scale cartography by genera-ting areas that consider the cantonal limit and the average height of urban areas. As a result, a projective system consisting of seven zones was obtained, which decreased the deformation value and increased the area of compliance at the continental level with respect to the results obtained when using the UTM projection system.
