The seemingly high tech electric vehicles were surprisingly first invented more than a hundred years ago. As with many early inventions it is hard to accord its origin to a single inventor, but the English electrical engineer Thomas Parker is said to have invented the first practical e-vehicle in the year 1884. There was a […]

Remote sensing is a tool for data acquisition through two primary techniques-active and passive. Active remote sensing is employed in polar regions during consistent cloud cover and darkness, where the sensor in orbit (eg., LIDAR and RADAR) sends its own signal and records the backscatter signal. During cloud-free conditions, however, the passive remote sensing measures […]

The monsoon in India is responsible for meeting the freshwater requirements of more than 1.3 billion people living in the country. The moist southwest monsoon winds bring plenty of rainfall from June to September. India’s GDP is closely linked with the monsoon as agricultural production is largely dependent on the quantum of rainfall (Gadgil and […]

Technology has always exerted tremendous influence on society and led to improved human productivity. According to a report by Barclaysanalysts, if human productivity was 100 units in 1765 it has increased to 3,000 units today (Barclays, 2018). In fact, it has doubled in just the last five decades and this steep increase coincides with the […]

The field of artificial intelligence (AI) has seen unprecedented growth in the last few years. Expectations are that AI may yield innovative technologies pervading almost all fields of influence including healthcare, education, safety, and transportation. At the same time, there are cautionary narratives suggesting the imminent danger of self-aware AI wiping out the whole of […]

India is home to abundant natural mineral resource and is one of the top ten producers of several minerals (Fig. 1). With a contribution of 1.53 per cent of gross domestic product in 2017-18, mining is an important sector for the Indian economy (Dash, 2019). There is growing realisation that the mining industry can significantly […]

Humans are dependent on natural resources to fulfill their basic needs—food, clothes and shelter. However, there has been decline in these resources over last few decades with unprecedented population growth. Resources like water, arable land and fossil fuels have become scarce due to over-consumption. With world population expected to increase to 8.3 billion by 2030, […]

High resolution satellite data in integration with other Earth science data has the potential to predict disasters and evolve methodologies for preparedness. Terrestrial factors, such as plate movements as well as extraterrestrial changes of the Sun and Earth’s environment are responsible for global changes (Mukherjee, 2006). Satellite based observations show that periodic monitoring from space […]

Remote sensing and GIS are promising tools for handling spatial and temporal data and help in integrating them for successful planning of natural resources. Remote sensing is the science of measuring the Earth using sensors mounted on high-flying aircrafts or satellites. These sensors collect data in the form of images and provide insights for manipulating, […]

India is culturally very rich and diverse and has a long history. This richness and history is visible in historical architectures and monuments. India has a vast number of heritage sites that showcase India’s history and culture and thus are of great national importance. Also, many of these heritage sites get huge national as well […]
