MARTINEZ TOBON, Cristian Danilo; AUNTA DUARTE, Jhon Eric  e  VALERO FANDINO, Jorge Alberto. APPLICATION LiDAR DATA IN ESTIMATING FOREST VOLUME IN THE METROPOLITAN PARK SAN CARLOS. Cienc. Ing. Neogranad. [online]. 2013, vol.23, n.1, pp.7-21. ISSN 0124-8170.

ABSTRACT LiDAR technology is a source of geographic information for obtaining coordinate points including height, with more accurately, one of the main applications is having LiDAR in forestry, but in Colombia the underdevelopment of this sector limits explore the convenience of using LiDAR data to estimate forest resources. This paper explores the use of LiDAR data for estimating forest volume in Metropolitan Park Forest San Carlos in Bogota DC Establishing a framework for background with similar studies; analyze a group of tools to manage LiDAR data and subsequently establishing a methodological procedure for a regression model relating the standard height data, with variable field, forest volume. Regression analysis was performed on decision criteria supported statistical testing various models to select the variables that best represent the phenomenon, establishing the goodness of fit test of the model and its parameters. Although the model is obtained did not produce the expected results in terms of estimating forest volume examines the causes of that happening. Finally the model is validated by applying it to the entire study area and represented geographically through a thematic map.
