Q4. What is the role of Satellite Images in Remote Sensing?

Remote Sensing technology collects the Earth's surfaces in the form of images. The collected images of this technology help to monitor and map natural resources and manage them appropriately. In recent years, the high-resolution data integrated with GIS tools have played an important role in mapping natural resources such as agriculture, forestry, geology, water, ocean, etc. It also makes it possible to monitor the environment and thereby help in conservation. Remote sensing is generally used to remotely observe and detect the specific objects. Technologies such as aircraft-based sensor and satellite assist in observing the objects in many areas such as hydrology, ecology, oceanography, geology and glaciology. Remote sensing supports many real-time applications such as military, intelligence, commercial, economic and satellite and aerial imagery planning. The main purpose of remote satellite imagery is to collect data from hazardous areas. Remote sensing is the fast technology in the digital world.

Q5. Why do we study Geospatial Technology and how it is useful?

Geospatial technology is commonly known as Geoinformatics. Geoinformatics technology is used for visualization, measurement and analysis of the characteristics or phenomena that occur on Earth. Geospatial technology is used in various organizations such as the civil, commercial, government and military sectors. The advancement of these technologies contributes to efficient management of natural resources. These technologies help in many applications such as soil, geomorphology, hydrogeology, land use, agriculture, land archives, town planning, infrastructure development, water resources, basin management slopes, disaster management, health, education, security and defense, etc. Geospatial is a widely used term it describe the combination of spatial software and an analytical method with a geographic database. The traditional technique for generating the state of natural resources is time consuming and expensive. The state of natural resources includes the area, crop production, irrigation facilities, rainfed areas, etc. this information can be generated using GIS and remote sensing technologies and would be cost effective and save time. Geospatial technology, including three different technologies that are all related to the mapping of entities on the surface of the earth. These three technologies are Remote Sensing (RS), Geographic Information System (GIS) and Global Positioning System (GPS). Geospatial technology improves organizational integration, makes decisions, and creates maps. Geospatial technology has become an essential part of everyday life. It is used to track everything from fitness to transportation to changes on the surface of the earth. "It's one of the finest technologies on the market.

Q6. . How do you see future of Remote Sensing and GIS in world?

All things considered, the future of GIS is very optimistic. It is about to be adopted on a larger scale than what we have seen in recent decades, as more and more organizations learn how much commercial value can come from geospatial data. We can expect that geographic information science and technology will not only transform, but will also help change the way organizations use these technologies. Everyone working in geographic information science understands the value of knowing exactly where you're headed. But the future of GIS presents endless possibilities thanks to innovative technologies and approaches. Geospatial methods have already radically transformed data collection and strategic planning in areas ranging from real estate to humanitarian aid. What happens next depends on qualified professionals and organizations that are implementing more and more space tools for a wide range of applications. The development of GIS applications pushes the limits of what we can do with spatial information. New approaches to creating software for use on the web or on mobile devices continue to proliferate, facilitated by widely available GIS APIs and open source maps. The resulting applications can inform government agencies and the public about the history of natural disasters in a region, show health professionals the best ways to serve the people of a region, or educate travelers on travel websites, interest and nearby hiking trails. As more and more developers adopt 3D GIS tools, these representations will include layers with unprecedented levels of detail that deepen our awareness of the relevance of geographic data.
