Satellite imagery provides an aerial perspective of the Earth’s surface and is a fundamental component of GIS where these photos are obtained by satellites with sophisticated sensors that can record information at different wavelengths. Different forms of imaging such as panchromatic, multispectral and hyperspectral are categorized to meet different analytical purposes. The capacity to gather,… Continue reading Importance of Satellite Images
The term “satellite imagery” describes the non-visual or visible data gathered by Earth observation satellites as they orbit the planet and with the use of sensors that record electromagnetic radiation at visible, infrared and microwave wavelengths, these satellites can provide a thorough picture of the surface of the planet. The main objective of obtaining satellite… Continue reading Applications of Satellite Imagery

Introduction Land Use Land Cover (LULC) Maps The terms land use and land cover are often used interchangeably, but each term has its own unique meaning. Land cover refers to the surface cover on the ground like vegetation, urban infrastructure, water, bare soil etc. Identification of land cover establishes the baseline information for activities like… Continue reading Significance of Land Use / Land Cover (LULC) Maps
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
The field of civil engineering has come a long way. One type of technology that aids modern civil engineers is geographic information systems (GIS). GIS can be used by engineers to collect and analyze geographic data. The data can then be displayed in layered visualizations using digital geographic maps. GIS (geographic information system) software analyses,… Continue reading GIS In Civil Engineering Applications
Through the analysis of data collected by a device that is not in direct contact with the thing, region, or phenomenon being studied, remote sensing is the process of learning more about an object, phenomenon, or location. A computer-assisted system for the collection, archival, analysis, and presentation of geographic data is a GIS based on… Continue reading IMAGE PROCESSING: A MAJOR ROLE IN GIS
