    1. IntroductionConnecting rural habitations through good quality all weather roads, which provide access to

    services and also opportunities for the rural population to increase their income, is an

    important part of the socio-economic development process. Connectivity enhances the value

    of every other rural investment, since it empowers people through improved mobility and

    access. People can more easily buy agricultural inputs and sell their produce. Children can go

    more easily to schools, cattle can more easily get veterinary help, and the sick can get to health

    centres. Roads can incubate a thousand small businesses, and can convert villages into towns.

    Rural productivity cannot be high without roads, but can be very high with them.

    For any road project to take place, the availability of a base map showing all the existing

    connectivity is very much essential, based upon which the assessment of unconnected areas in

    the region could be developed. The lack of proper road connectivity maps in local self

    institutions like Gramapanchayths has resulted in improper and non utilization of budget

    allocations.

    2. MethodologyBase map: A base map isvery much essential for the preparation of road map. Available maps

    like land use map/Panchayath Resource Map/Any other map may be studied for acting as a

    base map for the project. If no such maps are found, the cadastral maps from Survey

    department may be obtained. The cadastral maps of the villages coming in the Panchayath are

    to be collected and scanned and reproduced in various sizes as per requirement.

    List of Roads: It is desirable that all the roads in the panchayath area irrespective of its category

    NH/SH/MDR/ODR/VR are marked in the map. For this it is desirable to know all the roads in

    the area with their unique name and a unique id may be given to each of these roads.

    Mapping: The roads listed will be surveyed using hand held GPS and inventory details like cross

    sectional features, CD works, major land marks etc will be noted down. The GPS data will be

    used for obtaining the alignment map of roads in AutoCAD and GIS format. The roads will be

    numbered as in the road list. The final map will be handed over to the LSGI in AutoCAD as well
