Estimación de la incertidumbre en posición de una superficie digital del terreno obtenida por técnicas de LIDAR y fotogramétricas

Abstract

Knowing the precise coordinates of points obtained in the field, it becomes relevant when from these products as the Digital Land Area ( SDT ) are generated , and these in turn products are obtained : distances, areas and volumes. If points have errors , these are spread , affecting the accuracy of products. A mathematical model is provided for applying the method of measurement uncertainty and use the results as indicators of accuracy in position measurement obtained with LIDAR and Photogrammetric . The uncertainty of measurement is mathematically modeling the threads involved in obtaining XYZ coordinates .
