PLASTIC COVER GREENHOUSES REFLECTANCE SPECTRA FROM DIFFERENT OPTICAL SATELLITE IMAGERY

Abstract. Mapping the distribution of plastic covered greenhouses (PCG) is essential for any attempts to manage these complex areas intensive agriculture. It therefore important understand how spectrum different PCG varies in order establish its unique absorption features and can be utilised mapping from remote sensing imagery. This paper presents an analysis surface reflectance values satellite image spectra 50 PCG. The PCG, located Almería (Spain), was studied two seasons year (summer winter). All single bands WorldView-3 (WV3), Sentinel-2 MSI (S2 L2A) Landsat 8 OLI (L8 L2), together with Normalized Difference Plastic Index (NDPI) Vegetation (NDVI), were generated through object-based (OBIA) approach each season. results showed variability overall shape all main differences attributed crops specific characteristics their local management. A relationship between brightness whitewashing (greenhouse roof painted lime provide shade reduce temperature inside greenhouse, especially summer) found, showing ability temporally mask spectral signature film.
