ABSTRACT: This paper aims to explore how
field spectroscopy is essential for remote sensing studies for the detection
and monitoring of various features such military underground structures in
Cyprus. A SVC-HR1024 field spectroradiometer was used and in-band reflectances
were determined for medium resolution Landsat-7 ETM
satellite sensor, in order to study possible differences of the spectral
signature of vegetation throughout the phenological cycle of
plant growth. In this study, two test areas were identified, analyzed and modelled: 1)
Military Structure Area (MSA) where underground structure exists, and 2)
Reference Area (RA) where underground military structure does not exist. The
Normalized Difference Vegetation Index (NDVI) was applied to Landsat-7 ETM
and Sentinel-2 satellite images in order to identify the presence or absence of
underground structures in the study area.
