Resumo

In this research we built a detailed Digital Surface Model (DSM) of one ofthe biggest gully erosionfoundedin Rio Grande do Sul,located in the South of Brazil.The model was built using a DJI Phantom II UAV witha Go-Pro Hero 3+ on board. In order to estimate the coordenates of the groundpoints control (settled down with big white paperboards) we?ve used a cellphone GPS to get the latitude and longitude and pieces of woodenfenceto get the approximate difference in z axis between the groundpoints.It was taken and processed something about 1.089pictures in the software Photoscan. As results, we reveal that our unusual practices of field data management, which have used a very poor input data to build a very good Digital Surface Model, can be used to estimate environmental and important parameters in gully erosionstudies when there are no available topography data to be used.
