State-wide digital database and GIS of cadastral maps
So, to achieve a decentralised policy intended to bring administrative authorities closer to villagers and to collect land taxes from vast agro-economic resource, there is a need to have an effective, accurate and easy to access land revenue system. Succe-ssful developmental planning calls for production or updating of reliable base maps and land registration systems to guarantee land allocation and property rights which can well be achieved by digital conversion and correction of base cadastral maps.
Advantages of internet ready digital cadastral maps over Paper/cloth maps
Accessibility
Conventionally, keeping of Cadastral maps with plot-boundaries and their numbers written over them have been the prime responsibility of Village Patwari in Tehsil office. Differing paper/cloth records of land record system of the same region/area with different government departments like Forest and Revenue office have been giving rise to never ending property disputes and hindering proper development. This has led to a limited and monopolized system for any kind of information transaction. In turn this has led to widespread corruption and malpractices.
With digital version of maps and the availability of updated maps through government sale counters at district, tehsil and village level would reduce the rampant corruption and unnecessary land related disputes.
Quality
The conventional cadastral maps stored and maintained usually on a low quality paper or cloth are subject to various kinds of degrading factors like climate change, pests, wear and tear etc. These cannot be corrected easily without a fresh manual mapping for larger area in question and without putting enough time and money. However, a digital version of cadastral maps can be edge matched seamlessly and even corrected easily using high spatial resolution aerial photographs for any kind of scale transformation to any change in the plot boundary in question.
Updating
In a conventional setup both physical cadastral maps and land holding information are separately maintained manually whose modification and incorporation is a long process. The Tehsil/District/Village level Patwari records do not match with central records on a given date. However, in an internet linked digital database linked cadastral maps make it an easy process for any kind of online updating like computer railway reservation system.
