It's like layering different maps on top of each other, each layer containing specific information, such as roads, buildings, population density, or environmental data. GIS helps us see patterns, relationships, and trends that might not be obvious otherwise. For instance, a city planner might use GIS to analyze traffic patterns and identify optimal locations for new public transportation routes. Similarly, an environmental scientist could use GIS to map deforestation rates and identify areas at high risk.
    • Remote Sensing (RS): Remote sensing involves acquiring information about the Earth's surface without physically being in contact with it. This is typically done using satellites or aircraft equipped with sensors that detect and record different types of energy reflected or emitted from the Earth. Remote sensing data can be used to create images and maps that show a variety of features, such as land cover, vegetation health, and water quality. For example, satellite imagery can be used to monitor the spread of wildfires, track changes in glaciers, or assess the impact of natural disasters. The applications of remote sensing are vast and continue to grow as technology advances.
    • Global Navigation Satellite Systems (GNSS): GNSS, which includes GPS, is a network of satellites that provide positioning, navigation, and timing services. GPS is the most well-known GNSS, but there are others, such as GLONASS (Russia), Galileo (Europe), and BeiDou (China). These systems use signals from satellites to determine your exact location on Earth. This technology is used in everything from car navigation systems and smartphone apps to surveying equipment and precision agriculture. GNSS has revolutionized the way we navigate and track objects, making it an indispensable tool in modern life.

    Geospatial technology is not just about making pretty maps. It's a powerful tool for problem-solving and decision-making across a wide range of industries and disciplines.
