“The Future is Green Energy, Sustainability, Renewable Energy” – Arnold Schwarzenegger In an era of blooming greenhouse emissions and a high demand for Renewable Energy (RE) sources, the sustainable use of the conventional energy supplies is the foremost concern. Also quantifying and understanding the potential for a particular energy source has become crucial… Continue reading Geospatial Analysis: A basic dynamic for today’s Solar Developers
Building Height Estimation and its Applications Introduction Nowadays cities are developing, the demand for updating land topography and land use maps also increasing. Remote Sensing has many applications in Urban Planning and Management. Satellite Images provide useful information and data for very fine analysis of Urban areas for mapping, extraction, and height estimation of buildings… Continue reading Building height estimation and 3D modelling
Lidar (light detection and ranging) is an optical remote-sensing technique that employs laser light to densely sample the earth's surface, yielding highly accurate x, y, z measurements. Lidar, which is mainly used in airborne laser mapping applications, is gaining popularity as a low-cost compared to traditional surveying techniques such as photogrammetry. Lidar generates massive point… Continue reading GIS Integrated LiDAR Mapping and Its Applications
In the year 2022, the surface temperature of the Earth was 1.55 Degrees Fahrenheit warmer than the average of 57 Degrees Fahrenheit (NOAA,2023). As the world warms, the frequency and intensity of climate change related disasters amplify, posing a significant risk. Heatwaves, Droughts, Hurricanes, and typhoons have caused havoc across every area, leaving no continent… Continue reading The Role of Remote Sensing in Tackling Crop Insurance Anomalies
This image of South Qatar shows how the ebb and flow of the tide can create some unusual formations. Here, water and sand conjure up the shape and color of a tree as the tide swirls into the Persian Gulf. Qatar, an Arab Emirate in the Middle East, is one of the region’s wealthiest states… Continue reading Satellite image of Khor al Adaid, South Qatar
Introduction: Satellites look directly down at the earth, which show flat and map-like topography, but only few satellite images give us a sense of the landscape. On September 10, 2015, WorldView-3 followed an unusual route. As it passed over the Pacific, it turned back and looked at the continent to the east i.e. Los Angeles,… Continue reading “Looking through its legs” A New Kind of Landscape Photography.
The ‘smart’ revolution. We are living in a generation where most common and important word is ‘smart’. From smart people to smart phones and from smart maps to smart cities everything is getting smarter. Geospatial technology is progressing by leaps and bounds towards this smartness. The technology itself is getting smarter and contributing in other… Continue reading Planimetric Mapping
Introduction An AMDB is a Geographic Information System (GIS) based representation describing the topography of an airport. The geometry of aerodrome features is modelled by points, lines and polygons. Additional information characterizing the features and their functions is stored as attributes. Examples of attributes are name or identifier, quality parameters and surface type. Vertical… Continue reading AMDB | An Integral Part of the Modern Aeronautical Information Management (AIM)
Pipeline Monitoring System and Surveillance Pipeline equipped with pumps, valves, and other devices to transfer liquids, gases, and slurries from one place to another. Pipeline monitoring systems and surveillance provide a technique to monitor the condition of a pipeline such as evaluation of corrosion, preservation of the environment, leakage detection, etc. Airborne Pipeline monitoring… Continue reading Pipeline monitoring and surveillance using Geospatial Approach
The three most frequently used geospatial features generated by mapping systems are digital elevation models (DEM), digital surface models (DSM), and digital terrain models (DTM). Because each model employs a different methodology, each data product provides a different elevation value. Digital Elevation Model (DEM) A digital elevation model is a bare-earth raster grid referenced to a vertical datum.… Continue reading Elevation Models in GIS Environment
