ALTIMETRY AND PLANIMETRY, ANALYSIS OF PHOTOGRAMETRIC METHODS BY VANT VERSES CONVENTIONAL TOPOGRAPHY

Abstract

Altimetry and planimetry, make up Topography as important instruments in the study of landforms, allowing the obtaining and analysis of parameters for planning urban infrastructure and preservation of the environment, through mathematical and computational techniques for the treatment and planning of information geographic. The expansion of the use of these geotechnologies provides professionals in the area with the means to collect geographic information from physical entities, ensuring speed and quality in the design of products. Thus, this study aimed to compare the altimetric and planimetric products from aerial photogrammetry by UAV with conventional topography based on the costs involved, survey execution time and accuracies achieved. The method used to obtain the information consisted of an integrative literature review (ILR), from the synthesis of references available in works present in the literature for the comparative analysis of studies and scope of results. From the comparisons carried out, the results obtained showed a great advantage of using the UAV tool over conventional topography, as it allows reaching regions that are inaccessible or that offer some level of risk to workers. In addition, although the UAV presents obstacles in terms of standardization and treatment of supplied products, it still has advantages in terms of precision, time optimization and lower cost. In this way, the knowledge linked to the high precision of the area to be worked, proves to be fundamental for the consideration in the project or in the location of the project by the professionals of the Topography.
