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

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

During the building project, geographic information systems (GIS) can provide the necessary data to stakeholders, construction engineers, and consultants. Planners can use a GIS model to illustrate two-dimensional (2D) drawings and three-dimensional (3D) models by sequentially connecting their components to the operations in the schedule to demonstrate construction details. 3D GIS 3D GIS is the… Continue reading 3D GIS and 3D Modeling

In terms of economic development, infrastructure planning is critical. The use of GIS in this sector is extensive, and it may significantly save operational and administrative time and costs.GIS tools are now generally accepted to play a significant role in various sorts of infrastructure development. The majority of decisions made by local bodies at varying… Continue reading GIS For Infrastructure Planning and Development

GPS has been widely adopted by many government departments and institutions, as well as private enterprises, due to its positive impact. Services derived from the use of information technology, carrying efficiency, and benefiting from gadgets, resulted in a significant increase in interest and special focus in various areas for multitasking utensils and IT systems. GIS… Continue reading GIS and GPS enabled Vehicle Tracking System

The map is, of course, a visual representation of measurable data, and GIS stands for the geographic information system. A GIS map is more attractive than typical table maps. It can display previously overlooked features and demonstrate how these traits change over time based on the specified attributes. How Does a GIS Map Work? A… Continue reading GIS Integrated Cartographic Mapping
