Nowadays, remotely sensed images are used for various purposes in different applications. One of them is change detection using high resolution satellite imagery of city areas. Urbanization with rapid land use and land cover change has taken place in many cities of the world in the last 50 years. In this context, comparison of extraction… Continue reading Spatial and Temporal GIS Analysis Using Change Detection

Spatial decision problems typically involve a large set of feasible alternatives & multiple evaluation criteria most of the time, these are conflicting. Alternatives & criteria are often evaluated by a number of individuals (decision-makers, managers, stakeholders, interest groups). Most of the time, they also have conflicting ideas, preferences, objectives, etc.  GIS  techniques & procedures have an important… Continue reading Delineating groundwater prospect zones using Multi Criteria Analysis ( MCA)

Due to inappropriate land use, erosion has become one of the most dangerous forms of soil degradation leading to significant reduction of soil fertility and crop yields. The implementation of appropriate measures is strongly needed in order to prevent further degradation of soil. For this reason, GIS and Remote Sensing have been used extensively for… Continue reading Mapping Soil Erosion using USLE

Agriculture is undergoing a revolution with increased producer acceptance of an improved management concept called Precision Farming. Simply stated, precision farming promotes greater yields and reduced input costs by ensuring that the right things are done at the right time at right place and in right amount in the field. Precision farming is a knowledge-based… Continue reading Role of Global Positioning System (GPS) / Global Navigation Satellite System (GNSS) in Precision Farming

In September 2011, the China National Space Administration launched an 8.5 metric tones space station which was used as a technology protocol Chinese space station being live since 2013. Tiangong-1 since 2013, gathered data which helped Chinese find minerals and monitor ocean and for forecasting applications. The Chinese space station flies over land and sea… Continue reading Chinese Space Station Tiangong-1 Crashed

The villages around Maungdaw in Rakhine state of Myanmar witnessed a massive evacuation of the Rohingya settlements. The huge clearance of the land first by burning the villages and later by bulldozers have destroyed the Rohingya buildings, mosques, cemeteries and homes which has totally removed the roots of Rohingya history and culture. The temporal satellite… Continue reading Rohingya Massive Evacuation in Rakhine state of Myanmar

Better Resolution Enable Better Decision Making                                           Fig-1. (Offshore drilling rig, Kazakhstan, WorldView-3) Resolution matters. You cannot create a data from nothing and the laws of physics cannot be conquered via software enhancements. These indisputable… Continue reading Geospatial intelligence for energy companies

DRONE – Making Volumetric Calculations Worthwhile The people working in the construction, agriculture and mining industry very well understands importance of volumetric calculation of stockpile & its direct link to the success of their work. Whether the stockpile measurement is carried out to ensure availability of material enough to meet requirements or providing a financial report to… Continue reading Making Volumetric Calculations Worthwhile

Presently, the fish stock is not only under a threat from excessive legal fishing but also from illegal, unreported and unregulated (IUU) fishing which is why Global Fishing Watch (GFW) finds it difficult to estimate the precise level of such fishing activities. GWF enables active users with Internet access to monitor fishing activity at global… Continue reading Satellite Surveillance For IUU Fishing
