Preparation of Base Map Using High Resolution Satellite Data -A Case study of Allahabad city of Uttar Pradesh

摘要

Base maps of the backbone of all planning exercises. As per 2001 census, out of 5161 cities of India, only few had base maps. In Planning of a town or an urban area a large amount of the work is involved and often the major part is the determination of relevant facts to base the plan. The Plan or the Base map are paramount to represent spatial information. In the entire state of U.P., 0.06 lakhs sq.km. area comes under urban land, which is about 1.0% of the total land of the state. Due to excessive pressure of population, rapid urbanization took place and as a result of this, the urban density of the state is now reported around 4937 person per sq. km., whereas overall population density of the state is only 473 people per sq. kms. In the beginning of 20th Century, there were 548 towns in the state, which were raised up to 704 towns, in a span of 100 years. Accordingly, the cities/towns of the state achieved the status of Ist class cities/towns,, which were quite less in early years of 20th century, due to rapid urbanization in the recent years. In the present study, an attempt has been made to mapping the urban Landuse/Landcover of a part of Allahabad city of Uttar Pradesh using high resolution data through Remote Sensing technique coupled with G.I.S. This will certainly provides a base data for future & realistic planning of this important major city of U.P., which is essentially required by the urban planners.
