A comparative analysis of Resourcesat-2 LISS-3 and Landast-8 OLI imagery

Abstract

ABSTRACT:Linear Imaging Self Scanning Sensor (LISS-3) onboard Resoucesat-1 and 2 Satellites have been used extensively for various land cover-land use applications. In this study, we examined the potential of using Resourcesat-2 LISS-3 images in the absence of LANDSAT-8 Operational Land Imager (OLI) images. This paper compares the capabilities of LISS-3 sensor with OLI sensor. LISS-3 images were selected for comparison because of their close resemblance in electromagnetic spectrum range with LS-8 OLI images. Images of LS-8 OLI and RS-2 LISS-3 of the same area in Andhra Pradesh were used to evaluate the comparative performances based on the intra-inter band correlation, spectral vegetation indices and land cover classification. The results showed that in most cases the LS-8 OLI and the RS-2 LISS-3 images are comparable. This study also indicated that LISS-3 images could fill the data gaps in OLI images for land-cover studies, vice versa.

Road Feature Extraction from LANDSAT-8 and ResourceSat-2 Images

“…The bands in RS2 (B2, B3, and B5) are approximately matching with OLI sensor bands wavelengths, and LISS-3 bands, except the NIR band, has good correlation with OLI images [Venkateswarlu et al, 2014]. The spectral reflectance of Built-up, roads, Vegetation, and water features from the OLI and LISS-3 images shown in Figure 1 and observed that the features in both sensors are maintaining the same trend.…”
