What Is a UTM Zone and Why Does It Matter in GIS? Anyone working with GIS, surveying, satellite imagery, remote sensing or spatial analysis will eventually come across the Universal Transverse Mercator coordinate system, commonly known as UTM. While latitude and longitude identify locations using angular coordinates, UTM represents positions using coordinates measured in metres. For example, a geographic coordinate may look like: Latitude: 28.6139° NLongitude: 77.2090° E But

India experiences destructive floods almost every monsoon. Assam, Bihar, Uttar Pradesh, West Bengal, Odisha, Kerala and several Himalayan states regularly face river flooding, flash floods, urban waterlogging and landslides. Traditional flood monitoring depends on rainfall records, river gauges, field surveys and weather forecasts. These systems remain essential, but they cannot always show the complete geographical extent of a flood—particularly when roads are blocked, villa

When checking air pollution in India, you may encounter three common terms: AOD, AQI and PM2.5. Although all three relate to particles in the atmosphere, they do not measure the same thing. In simple terms: AOD shows how much aerosol is present through a vertical column of the atmosphere. PM2.5 measures the concentration of fine particles near the ground. AQI converts multiple pollutant measurements into an easy-to-understand air-quality score. Understanding these differences
