Assessing Usefulness of High - Resolution Satellite Imagery (HRSI) in GIS - Based Cadastral Land Information System

The emerging new satellite technologies enabling earth observation at a spatial resolution of 0.6m or even 0.41m together with powerful and high speed computing and processing capabilities have brought revolutionary changes in the field of GIS-based cadastral land information system. The high-resolution satellite imagery (HRSI) is showing its usefulness for cadastral surveys due to which traditional cadastre and land registration systems have been undergoing major changes worldwide [1]. In this way the traditional surveying concept has taken up into new shape from discipline-oriented technologies, such as geodesy, surveying, photogrammetry and cartography into a methodology-oriented integrated discipline of geoinformation. Such methodologies are based on global positioning system (GPS), remote sensing (RS), and digital photography for spatial data acquisition [2]. The developments in the field of Geographic Information System (GIS) technologies have given a new insight in addressing a variety of land development, management, and planning activities for better use of land in resource management. Due to rapid development in the space born technology nowadays it is possible to generate thematic maps on various scales keeping in mind end users’ requirements. The locational accuracy of maps is utmost important for certain applications like cadastral Centre for Research on Settlements and Urbanism
