Impact of Spatial Resolution on Coastal Zone Mapping

Alpana Shukla, H. B. Chauhan

Abstract :

Coast is an area where air, land and ocean waters meet. India has a long coastline of 7516.6 km (Nayak S.R. et. al., 1992). The present paper reports the study of the impact of spatial resolution on the classification of various wetland and landuse classes in the coastal zone. Hazira area near Surat city was selected for the study area as many anthropogenic activities have taken place and many more developmental projects are coming up in this area. The landuse / landcover change is very rapid, thus making this area highly vulnerable. Data from LISS III, LISS IV and CARTOSAT have been used for landuse classification in the study. CARTOSAT PAN data was merged with LISS IV to classify various coastal wetland and landuse features. The classification system developed by SAC for wetland and landuse mapping in Coastal Regulation Zone (CRZ) has been used (Nayak et. al., 1991). Certain features, which are visible but not possible to map at the medium resolution data, can be identified and mapped using merge (CARTOSAT + LISS IV) data. Merging the CARTOSAT and LISS IV data allows to exploit full benefit of spatial and spectral resolution. Merged data allow differentiating various vegetation classes, which is not possible using CARTOSAT data alone. Improvement in spatial resolution enhances the interpretability and the accuracy of the mapping in the coastal zone. Thus satellite data like LISS III and LISS IV can be used to prepare wetland and landuse maps on 1: 25,000 scale, which can be used for regional planning; where as CARTOSAT merged data (CARTOSAT + LISS IV) can be used to map the coastal zone on 1:5,000 scale, which can be used for local level planning
