Estudo de áreas em levantamento planimétrico por caminhamento e irradiação em teodolito digital e analógico

The objective of this work is proceeding to determine a defined area using different methods of planimetric and topographic survey instruments. To survey instruments were used for this polygonal such as fiberglass tape measures using geometrical methods for the determination of the area; traversal by using the lifting analog and digital theodolite, processing the distance data obtained with estadimetric; lifting and also by irradiation using theodolite digital and analog readings estadimetrics proceeding. The survey data were processing on Microsoft Excel ®. It was found that all methods of planimetric survey, either by irradiation and pathway, were effective in determining the approximate area of the polygon implanted with least significant difference between the types of survey instruments in the area 2. The smallest average error was made up with the analog instrument in area 2 (0.6%), while the largest error occurred with the digital instrument in area 2 (2.06%). The coefficient of variation was greater in the digital instrument in area 1 (1.41%) and lowest in the area with 2 analog instrument (0.37%).
