Land Viewer: Download Latest Satellite Imagery and Analysis Spectral Indices on any Browser

Image
Recently, a team of Data Scientist, Software Developers and Geo-Scientist from California-established company Earth Observing System (EOS) had launched innovative cloud based tools for exiting Remote Sensing and GIS users, students, researchers and more user-friendly for the people new to GIS and Remote Sensing.    Land Viewer tool is the real–time image processing and analytics like: Access to Latest Imagery from Sentinel-2 to Oldest Imagery of Landsat MSS and TM. Easy to find the required geospatial imagery of any scale by selecting the Area of Interest on the map. Using land viewer on-the-fly imagery analytics abilities and download required image for various analysis. Using the Earth Observing System algorithms, users can compare two satellite imagery for finding the difference and selecting needed imagery for the analysis. For Example, Sentinel-2 and Landsat-8 imagery using option called “Comparison Slider” which is real-time level faster...

Ground Truth Analysis using Google Earth - Is it possible?

Image
Hello friends, I Know that the topic (Ground Truth Analysis using Google Earth) is bit wired. Before that we have to  understand what is ground truth verification. Ground truth verification is process through which physical verification or field visit to region, for checking  level accuracy which is analysed in satellite image is same as the real world information. Now lets discuss the process using google earth, so most of the image analyst use Erdas Imagine for classification Land-use and Land-cover and etc. In this case the satellite imagery are 30m in resolution that not really  accurate. Now there's option to synchronize your satellite imagery with google earth  through which we can identify the feature in the satellite image through google earth up-to significant level.  This is really useful in saving your time, energy and cost reduction by more accurate visual ground truth analysis. In the above video tutorial the steps have...

Mosaic Multiple Satellite Imagery

Image
Mosaic Satellite Images Mosaic Satellite Images is certainly important and needed for most researchers and students, that too analyzing  larger study area covering two or more satellite scenes. Hence for providing better assistance, I am providing some productive ways for Mosaicing Satellite Images using Erdas Imagine. If  you have further doubts please visit this link below:  Tutorial - Mosaic Satellite Imagery Erdas Imagine is popular remote sensing software through which mosaic process can be effectively done. Open Erdas Imagine through which add the satellite imagery’s and proceed to raster option from which mosaic tool is visualized. Select Mosaic Pro add the satellite images to tool and run the process mosaic will be completed in few minutes. Things to Remember   When downloading satellite image make sure that each and every satellite image date does not exceeding two weeks, otherwise color variation will happen. This due climatic variation...
