Introduction
The cities are like trees; both of them grow under natural limits. These limits affect in the formulation of a city’s master plan (Mahrous, et al, 2002). In India, rapid urbanization is resulted due to the unprecedented population growth coupled with unplanned developmental activities. This urbanization, which lacks in infrastructure facilities, has posed serious implications on the resource base of the region. The urbanization takes place either in radial direction around a well-established city or linearly along the highways (Guwahati Path finder, 2000). The city of Guwahati in India provides a typical case of haphazard and unplanned urbanization.
Keeping these perspectives in view, attempt has been made to provide opportunities to realize a strategic assessment to determine the current status of land use, land suitability information, identification of the patterns of change during the past years, assessment of the impact of infrastructure development in terms of zoning regulations, transportation facilities, public utilities, drainage system, population, industry, tourism etc to meet the challenges in Planning and Management of Guwahati City using integrated remote sensing and GIS technology.
The data elements (Landuse/landcover, infrastructure, drainage etc.) which has both static and dynamic components pose a formidable challenge for proper maintenance and operations in different sectors concerns. Due to development of automation in technological processes applied to data gathering, integration and processing of topographic details and their customized presentation, analysis and interpretation the challenges can be met with the help Desktop GIS system. While Geographical Information System (GIS) involves in integration of spatially referenced data in a problem solving environment, GIS-based Land Information System (LIS) is an interactive computer-based systems that help decision makers utilize data and models to solve unstructured problems. Combining both the ideas, in the present times such powerful software technology has been developed that allows virtually unlimited amounts of information to be linked to a geographic location. Coupled with a digital map, GIS records, stores, and analyzes information about the features that make up the earth's surface, thus allowing a user to see regions, countries, neighborhoods, and the people who live in them with unprecedented clarity (Betty, et al, 1998).
In this study an integrated remote sensing and GIS based methodology is developed and successfully tested by generating an up to date digital database. Finally a Land information System (LIS) is designed for the city development authorities.
