Comparação entre o método convencional (GNSS) e o método da aerofotogrametria com vant para o georreferenciamento de imóveis rurais

Abstract

In order to change the results in the geo-referencing of rural properties, the use of new technologies is essential. In this scenario, an aerial photogrammetry is being implemented by the National Institute of Colonization and Agrarian Reform (INCRA) from a national aerial vehicle (VANT) to carry out fieldwork for surveying rural properties. Usually the most used method for performing services is GNSS, with the use of high precision receivers, being a method that meets the standards stipulated by INCRA. Note that this method in addition to cost-benefit, due to equipment and time of completion, makes it difficult to install the services in an area of access to rural properties, for example, often impossible, the lack of detail. Therefore, an aerial photogrammetry has been gaining space in the works, due to the performance of a smaller equipment, shorter survey time, more information. Thus, an aerial photogrammetry can be met as INCRA survey standards, and can be used in geo-referencing of rural properties. In view of the above, the comparative research between conventional and conventional aerial photogrammetry, verifying operating costs, positional precisions and attendance to the current technical technique. With the results, the two methods were found to be normative, with a series of advantages for the VANT method.
