Remote sensing is a vital technology that revolutionized how we observe, understand, and interact with the Earth’s surface and atmosphere. It encompasses the acquisition, processing, and interpretation of information about objects or areas from a distance, typically through the use of satellite or airborne sensors. The science of remote sensing plays a central role in …
The term Synthetic Aperture refers to the technique SAR uses to achieve high spatial resolution where by moving the radar along a flight path and combining the signals over time, Synthetic Aperture Radar effectively synthesizes a large antenna aperture increasing the resolution beyond what a real antenna of similar size could achieve. This results in …
A Digital Elevation Model is essentially a raster dataset that stores elevation data for a geographic region. Each pixel (or cell) in the raster contains a value representing the elevation at that specific location. DEMs are typically represented as a grid, with rows and columns corresponding to latitude and longitude. The resolution of the DEM …
Satellite imagery is a critical component of the Geographic Information Systems (GIS) industry, offering a bird’s-eye view of the Earth’s surface. This technology captures images from space via satellites equipped with advanced sensors, providing detailed information that is invaluable for a variety of applications. Satellite imagery refers to images of the Earth or other planets …
GIS is a technology that enables the collection, analysis and visualization of spatial data and in the context of disaster management, GIS helps in mapping hazards, assessing vulnerabilities and coordinating response efforts. The technology leverages various data sources including satellite imagery, sensor networks and field surveys to create dynamic maps and models that support decision-making …
Satellite communication involves the use of artificial satellites to provide communication links between various points on Earth and this technology is crucial for global telecommunications, broadcasting, weather forecasting and navigation. In the context of GIS, satellite communication enables the acquisition, transmission and dissemination of geospatial data which is vital for various applications ranging from environmental …
Drones, also known as Unmanned Aerial Vehicles (UAVs), have become increasingly popular in agriculture due to their ability to collect high-resolution aerial data quickly and efficiently. Equipped with advanced sensors and imaging technologies, drones can capture detailed information about crops, soil, and environmental conditions. This data is invaluable for precision agriculture, which aims to optimize …
Starlink formerly the SpaceX Starlink project is a massive constellation of tiny satellites whose primary goal is to establish a dependable and easily accessible global broadband internet service especially in remote and impoverished areas. The constellation is envisioned orbiting the Earth at heights of between 340 and 1,200 kilometers. Compared to normal geostationary satellites, which …
Our perception and comprehension of our world have been completely transformed by satellite images which is the foundation of the Geographic Information System (GIS) sector and these high-resolution space images offer a multitude of data for a variety of uses including disaster relief, urban planning and environmental monitoring. This process explores the technical features of …
Spatial and geographical data can be captured, stored, analyzed and visualized using GIS technology and to provide a thorough picture of agricultural landscapes, GIS integrates various data sources including satellite imagery, GPS, weather data, soil information and crop yield statistics. Thanks to this spatial intelligence, precision agricultural techniques are made possible by farmers’ ability to …
