As we discussed in our previous post Landsat Data Continuity Mission is the latest workhorse after Landsat EMT+. It was launched on 11th February 2013 from Vandenberg Air Force Base in California. Landsat 8 has the ability to capture a 185 km swath of Earth and is meant to provide a regional and national scale… Continue reading Landsat 8 Acquires First image : LDCM successful
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

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
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
Land cover maps are essential for making wise decisions about policy, development, planning, and resource management. The production of accurate and appropriate land cover maps for use in developing regions, however, is hampered by technological, capacity, and institutional obstacles. Many developing regions lack the integrated capacity, infrastructure, and technologies needed to create a reliable land… Continue reading Land Cover Assessment and Mapping for Sustainable Environment
As we said in a last year’s post and another post about WorldView-3 replacing the GeoEye-2 sensor in launch priority, the new sensor is all about breaking new ground. The current WorldView-3 sensor launched on August 31st, 2014, is a massive technological achievement as evident from following sample images released by DigitalGlobe. Please note that these images… Continue reading 31cm WorldView-3 Sends First Crisp Images
The latest in the series of Landsat satellites the LDCM, Landsat Data Continuity Mission was launched today from Vandenberg Air Force Base in California. This satellite continues the four decades old legacy of the Earth Observation from space. The first Landsat satellite launched in 1972. The joint program between NASA and the U.S. Geological Survey… Continue reading Landsat Data Continuity Mission Launched !
Introduction As per the American Society for Photogrammetry and Remote Sensing (1987), photogrammetry is the art, science, and technology of obtaining reliable information about physical objects and the environment by recording, measuring and interpreting photographic images. The word photogrammetry is derived from three Greek words: photos – meaning "light", gramma– meaning "drawing" and… Continue reading Concepts of Photogrammetry
