Índices de vegetación a partir de datos obtenidos mediante sistemas VANT

Abstract

In this research vegetation indices were generated such as: RATIO, NDVI, RVI, PVI, DVI and SAVI; for this purpose it was used data obtained through a system UAV (Unmanned Aerial Vehicle) and images from a multispectral camera. The used images was captured by the camera in the bands red (RED) and near infrared (NIR) of the electromagnetic spectrum, at a spatial resolution of 10cm x 10cm. Using different combinations of these bands multiple vegetation indices were calculated for detecting the state of vegetation and assess which index is best adapted for monitoring the vegetation. The selected study area was the Malacatos parish located in the south of Ecuador, province of Loja, canton Loja. The vegetation was monitored in the transition between the rainy to the dry season; the temporal interval was 28 days. The generated vegetation indexes indicated that the vegetation in the study area is affected by the deficit of water resources in the dry season, where the DVI index has shown the best results in determining variations in the different vegetal coverages.
