In this blog, we’ll share how global composite satellite imageries are constructed by using Landsat 8, Sentinel-2A and Sentinel-1 satellites and how they appear. Composites: A Perfect Summer’s Day When we see satellite images in Google maps then we notice a strange thing that is the satellite data is cloud free and the greenery looks… Continue reading Using Petabytes of Pixels to Create 3 New Images
Most Recent Trends in Geospatial Market’ Change is the only constant – though an old adage, is quite relevant in the present context.’ Geospatial Technology This is commonly known as geomatics and refers to the technology used for visualization, measurement, and analysis of features or phenomena that occur on the earth. It is synonymous with… Continue reading Most Recent Trends in Geospatial Market
“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 as… 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
One of the areas where GIS is most beneficial is aviation. The management of planes at the airport and other duties employ geographic systems. Aviation GIS must be extremely precise, effective, and dependable. For the airports and planes in general to perform smoothly, it must also operate on a real-time basis. Diverse operations can be… Continue reading Aerospace Industry As An Application Of GIS
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)
