A city is a large human settlement. People are the main driving force in a city. The dynamism of a city is dependent on people and their behaviour. A preliminary understanding of the composition and diverse capabilities of the populations in a city should be the key to a successful urban study.
Predictions made by identifying demographic and composition patterns of the population within the existing physical boundary will create a well-planned livable city.

Proper management of land, a scarce resource, can bring about many benefits. This is of great importance especially in urban areas.
It is timely to figure out how land is allocated and being used for what purpose in our cities today. In order to create well planned cities with a futuristic vision, having a better understanding of current land use is imperative.
Land use maps are categorized into 36 sub-categories under two types – built-up and non built-up. The extent of land in each of these sub categories are indicated below.
In all of the cities it can be identified that the higher densities are concentrated in the city centres and the expansion is taken place along the roads. The expansion pattern is shaped by the geography of the surrounding area.
The selection of the area for the urban expansion analysis was followed by several preliminary studies. Initially, the urban index values which was identified using the remote sensing information were studied in the respective municipal areas including a fringe area.
Before selecting interested area for the expansion analysis it should consider following facts
- Municipal boundary
- At least 2-3 km buffer around Municipal boundary
- Rough boundary where the physical urban character disappearing
In the remote sensing discipline, the values higher than 0 represent the built-up areas.The boundary for the fringe area was identified by getting the extent of urban expansion as well as a fine boundary where the high-density expansion become insignificant. The identified boundaries were projected on to the latest satellite images to assure the identified urban index values are in line with the existing building densities.
