The changing scenario in governance especially for survey and land records department in state demands advanced information technologies and tools. The need of the day is creation of a comprehensive Land Information System, which has great potential in the field of land records management and can be used as multi-purpose administrative tool.
Digital cadastral map in coordinate system can be used as one of the input to create LIS. Use of modern equipment, GPS and Total Station not only gives accuracy but also one can prepare coordinate based land parcel information. Mapping software can be used to directly download the observed data in computer system.
The main objective of the present study is to prepare the coordinate based cadastral map for the part of Chennai city using Total Station , GPS and drafting software.The methodology consists of boundary demarcation, traverse survey, computation of data, preparation of skeleton ,location of holdings and field demarcation , field measurement., plotting of village map and finishing the map and area computation.
The methodology is fundamentally based on conventional procedure adopted by Survey of Land Records Department (SLRD), Government of Tamilnadu. The modern methodology adopted is the use of Total Station , GPS and CAD instead of chain, theodolite and manual drafting. This enables to maintain the earlier records intact and also to convert the field measurement skeleton into coordinate based digital cadastre. For the study an extent of about 40 ha comprising of Anna University campus has been taken up for demonstration. The maps were prepared and it is envisioned that same procedure can be adopted in Urban and rural cadastral survey. The main advantages are speed, realistic accuracy and simpler field operation.
