On Feb 15 early morning, a meteor darted across the sky above Russia’s Ural Mountain range. The fireball exploded near Chelyabinsk, injuring hundreds of people, creating a sonic boom and damaging hundreds of buildings and causing injuries to thousands of people. The injuries were mainly from the falling glass and other building material taken apart… Continue reading Meteor Strike over Russia: Was it the first?

"The greatest wealth is health" isn't it so true? Environmental health The science of preventing diseases, prolonging human life and promoting human health through an organized effort is called public health. Environmental health is a branch of public health. When we talk about the impact of environment on human health we are considering both natural… Continue reading Environmental Health and Geospatial Technology

Many sensors carried aboard satellites measure red and near-infrared light waves reflected by land surfaces. Using mathematical formulas (algorithms), one can transform raw satellite data about these light waves into vegetation indices. A vegetation index is an indicator that describes the greenness i.e. the relative density and health of vegetation, for each pixel in a… Continue reading Significance of Spectral Indexes in Accurate Vegetation Analysis
Our world is changing and becoming high – tech. Everything is being abstracted and modelled by digital twins. They use automation to improve business processes, reduce risk, maximise operational efficiencies, and improve decision-making by predicting outcomes. By establishing relationships and standardising workflows, digital twins add information to the solution of business problems. GIS (geographic information… Continue reading Digital Twin – An Emerging Technology for Geospatial World
Canadian researchers made the initial attempts at geographical data analysis in the 1960s. The systematization of the nation's natural resources was the first goal for GIS applications. Since then, spatial analysis in GIS has become more widespread. It is challenging to think of a single business owner or super industry that does not gain in… Continue reading Spatial tools: Making GIS Analyst lives easier
India has a vast amount of geospatial information generated through various topographic surveys, geological surveys, soil surveys, cadastral surveys, various natural resources information generated with the use of the remotely sensed imagery. Encapsulating these maps and images into a National Spatial Data Infrastructure (NSDI) is expected to provide information transparency and sharing. One of the… Continue reading SATPALDA Participates in NSDI 12
Archaeology can take you to the past as archaeologist finds the remnants of ancient civilisation and spend years to dig them. But it is a time taking process as archaeologists have to depend upon literature reviews and field data. Sarah Parcak is founding director of the University of Alabama in Birmingham`s Laboratory for Global Observation.… Continue reading “Space Archaeology” to explore ancient sites.
A series of devastating floods in China during July-November 1931 was one of the most lethal natural disaster of 20th century. Estimates of the total death toll range between 1,000,000–4,000,000. The Great Peruvian earthquake occurred on 31 May 1970 off the coast of Peru in the Pacific Ocean is among the most catastrophic natural disaster.… Continue reading Geospatial Data For Disaster Management
