Objectives Maritime transportation has been benefitting the humankind since ages whether it being used for trading or transportation, since past few decades we are observing a rapid increase in international and inland waterway on world scale, currently, about 90 percent of intercontinental trade is handled by sea transport. Sea port forms a platform where all… Continue reading Maritime Port Management with GIS
Introduction Precision forestry is a method in which the characteristics of forests, treatments, biodiversity preservation, and recreational opportunities can be accurately determined, at the forest stand, plot, or individual tree level. Precision forestry requires a plethora of information and data which needs to be accurate, spatially detailed, up to date, and must characterize the… Continue reading Precision Forestry : A Revolution through Remote Sensing Technology
TREE CROWN MAPPING USING LiDAR Importance of Tree Surveying We are well aware of the fact that trees are the integral part of our eco system as well as our flora and fauna. Mapping forest reserves and vegetation is critical to economic development and to understanding our environment; it provides information about the age… Continue reading LiDAR for Tree Crown Mapping
Many sensors carried aboard satellites measure red and near-infrared light waves reflected by land surfaces. Using mathematical formulas (algorithms), one can transform raw satellite data about these light waves into vegetation indices. A vegetation index is an indicator that describes the greenness i.e. the relative density and health of vegetation, for each pixel in a… Continue reading Significance of Spectral Indexes in Accurate Vegetation Analysis

How modern Geospatial technology can be an asset in climate change studies? Introduction: Climate change is the most important and defining issue in the present scenario. Climate change refers to the changing climatic pattern and rise in the average surface temperature of the earth. Climate change is evident from the changing weather pattern, melting… Continue reading How modern Geospatial technology can be an asset in climate change studies?
The Food and Agriculture Organization (FAO) defines sustainable development as 'sustainable development is the management and conservation of natural resources base and the orientation of technological and institutional changes in such a manner as to ensure the attainment and continued satisfaction of human needs for present and future generations. Such sustainable development conserves land, water,… Continue reading Geospatial Technology Fostering Sustainability and Sustainable Development Goals
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
Introduction Nowadays forests resources play an important role in mitigating climate change by sequestering carbon in their Forest biomass estimation. Biomass (B) is an assessment of how much living tissue mass is present in a population at one point in time. The health and environmental conditions of a forest ecosystem are reflected in biomass. Biomass… Continue reading Forest Biomass Estimation
Bathymetry is recognized as an essential component in marine applications because it is used in many coastal erosions tracking and engineering projects. Traditionally, it was obtained via shipboard echo sounding, but nowadays, multispectral satellite imagery is also commonly used with various remote sensing-based algorithms. The surface reflectance of shallow coastal waters is related to the… Continue reading Bathymetry Estimation and Marine Mapping
