For these clearances, the mariner has to know correctly and accurately the following:1. Location of the sea floor or ocean depth,2. Height of the overhead structure,3. Locations of the ship’s keel and mainmast.

The three prime entities that are involved in the maintenance of Land information system (LIS) are the Department of Revenue, Department of Survey, Settlement and Land Records, and Offi ce of land registration. In addition to this, the appropriate municipal or village administrative unit is also involved. This is the convention in many states in India. The land records in India, do not provide ultimate title to property. In other words we need a system of effi cient maintenance of land records which is essential for protection of land rights of several millions of people in the country. Land has been one of the most sought after possessions in developing countries such as ours, wherein, the land holding has socio economic significance and status. Thus there is a need to develop an integrated LIS. A lot can be said and discussed about various activities and issues that are being dealt to create a LIS in different parts of the country. There are some success stories in Karnataka and some efforts of Governments in the states of Andhra Pradesh, Gujarat and Madhya Pradesh.

Seven out of ten customers of surveys and mapping who talk to the suppliers (consulting fi rms of surveying agencies) demand their maps to be delivered `yesterday’(!) or indeed as early as possible. These customers are `decision-makers’ who have taken some months (if not years) to come to the demand level! Same is the situation in respect of the tenders in mapping discipline. All the risks and uncertainties are put on the door of the suppliers / contractors. One should realize that although the surveying and mapping process never costs more than 1 or 2 percent of total budget, the same is not true when it comes to the time taken for the mapping project. The fact is that many projects are delayed just because the survey data of right quality and proper map was not made available to the engineer / planner.
