Abstract

TRABAQUINI, Kleber et al. Identification and spatialization of apple orchards using remote sensing data in the state of Santa Catarina-Brazil. Rev. de Ciências Agrárias [online]. 2021, vol.44, n.2-3, pp.11-20.  Epub Jan 21, 2021. ISSN 0871-018X.  https://doi.org/10.19084/rca.18101.

Santa Catarina has national prominence in the cultivation of the apple, but currently the data of cultivated area are collected through subjective methodologies. In this sense, the present work aims to present an area estimation methodology using remote sensing techniques. In addition, through SRTM and meteorological data, the spatialization of one of the factors essential to apple cultivation, the chill hours (CH) was carried out, which determines bud break and consequently orchards productivity. Results showed that by means of orbital images a mapping with 93.4% of Kappa index was possible, fact obtained mainly by the use of Sentinel-2 and Cbers-4 images. About 73% are in an altitude range between 1,100 and 1,400 m. In relation to the Chill Hours, orchards implanted between 700 and 900 CH total 71.3% of the production area. The applied methodology and the results achieved in the present work show great potential for the mapping of other apple producing regions in the state.
