The multi-billion dollar a year activities linking aerial imagery with geospatial technologies expands more rapidly than you can blink an eye. Government and commercial contracts dominate the growth, especially for military, security, agriculture, and forestry applications.
Smart city is the city of tomorrow, which tries to identify a smarter option from legacy system for maximizing the end-user satisfaction and accelerating urban socio-cultural and economic development. Smart city is knowledge based city functioning on most latest and updated information on automated decision-making and rapid action for individuals.

Satellite Imagery provides much essential and critical information for monitoring many applications such as image fusion, change detection, and land cover classification. Remote sensing is an important technique to obtain information relating to the Earth’s resources and environment.
The Landsat program is the longest-running enterprise for acquisition of satellite imagery of Earth. On July 23, 1972 the Earth Resources Technology Satellite was launched. This was eventually renamed to Landsat. The most recent, Landsat 8, was launched on February 11, 2013. The instruments on the Landsat satellites have acquired millions of images. The images, archived in the United States and at Landsat receiving stations around the world, are a unique resource for global change research and applications in agriculture, cartography, geology, forestry, urban and regional planning, surveillance and education, and can be viewed through the USGS ‘EarthExplorer’ website. Landsat 7 data has eight spectral bands with spatial resolutions ranging from 15 to 60 meters; the temporal resolution is 16 days. Landsat images are usually divided into scenes for easy downloading. Each Landsat scene is about 115 miles long and 115 miles wide (or 100 nautical miles long and 100 nautical miles wide, or 185 kilometers long and 185 kilometers wide).
Good geographic information system (GIS) questions are not easily created. They can be mysterious to some, unknown to others and cause others to scratch their heads in curiosity. Since most questions posed to GIS are relatively simple – where is this? Most users have their answers satisfied and move on. But a much smaller number of people seek answers to more complex questions that are not immediately available – or even understood.
