Cadastral resurvey and integration of geospatial technique using high-resolution satellite image (HRSI): a case study in Indian district

Recent developments in digital airborne sensors and satellite platforms make spatially accurate, high-resolution satellite image (HRSI) readily accessible. The potential of geospatial technology provides the opportunity to solve complex old real-world problems. Improvised ground-based survey methods involve detailed survey, which provides highly processed three-dimensional coordinates for surveyed points. An assessment of the capabilities of these increasing spatial resolutions of satellite imagery and hybrid survey systems for the updation/resurvey of land information, such as land parcel size and their real earth position, has been done in this study. It compares chain and tape surveying, traditional survey methods with HRSI-based surveying. This study aims to assess the viability of improvised geospatial technique for surveying in the land modernization program. This study assesses the accuracy of three different methods for comparing land information: (1) old traditional method of land surveying, (2) conversion of hard copies of cadastral maps into digitized maps using computer-aided technique, and (3) improvised ortho-HRSI-based geospatial technology. A discussion of the results and relative merits of each method is included in this study. Even though the area measurement method by ground and computer-aided technique is discrepant, there was a considerable matching of digitized cadastral map to the land records area. The study indicates geospatial technology can be adapted further to other villages and districts and digital information can be updated frequently. This paper provides an overview of the development and maintenance of digital cadastral assessment maps and parcel data layers in a geographic information system. It describes digital mapping system components, modern survey techniques, and the creation of digital maps.
