Abstract
Man, Land and the Natural Resources supported by land always had an intrinsic and dynamic relationship. Land information is crucial for planning and development. The rapid pace of development in many of the cities, while bringing high growth rates also brings with it heavy burdens on land utilization. To ensure that the high growth rates can be sustained, it is imperative to plan for an effective Land Information System, to plan the utilization of its land resources for development, while at the same time protect the environment. Planners of the 21st century are handicapped today. The reason: lack of authentic and upto date information, be it about the beneficiary groups, existing facilities, terrain and soil conditions or land ownership and occupancy details. Land information refers to any physical, legal, economic or environmental information or characteristics concerning land, water, groundwater, subsurface resources, or air in the state. Land information has been used in a variety of systems over the years, from register of deed tract indexes to surveyors tie sheets or soil surveys. Today many organizations are moving land information into Geographic Information Systems (GIS). Land information is an integral part of government, non-profit, and private sector activities. Adopting GIS/LIS techniques can advance broader social purposes by making more effective public decisions and by using natural resources in a more optimal way. This paper is not only aimed at addressing the urgent need for a Land Information System at various levels but also an eye opener to the problems involved in creating a LIS and a curtain raiser to the customised GIS based application for cadastral mapping/LIS that has been developed at Pixel Infotek. The paper discusses various aspects and components of cadastral maps and the innovative user friendly tools that have been developed at Pixel Infotek for digitising various categories of cadastral maps like Town Maps, Block Maps, Ward Maps, Village Maps, Survey Fields etc. The customised GIS based application has been developed on Bentley’s flagship product MicroStation/J Geographics and it provides the user with the flexibility to use native languages in cadastral maps/ LIS. The application has been developed after years of groundwork in this field and keeping in mind the local requirements. The developed application can be customised further to any local requirements. Introduction Land information is crucial for planning and development. The rapid pace of development in many of the cities in India, while bringing high growth rates also brings with it heavy burdens on land utilisation. To ensure that the high growth rates can be sustained, it is imperative to plan for an effective Land Information System to plan the utilisation of its land resources for development while at the same time protect the environment. Land information refers to any physical, legal, economic or environmental information or characteristics concerning land, water, groundwater, subsurface resources, or air in the state. Land information has been used in a variety of systems over the years, from register of deed tract indexes to surveyors tie sheets or soil surveys. Today many organisations are moving land information into Geographic Information Systems (GIS). A Land Information System (LIS) is similar to GIS but is more focused on land records and detailed views of these records. GIS and LIS systems provide tools that support many types of record keeping, analysis and decision-making. Land information is an integral part of government, non-profit, and private sector activities. Adopting GIS/LIS techniques can advance broader social purposes by making more effective public decisions and by using natural resources in a more optimal way.
