Orfeo ToolBox (OTB) is an open source project for state-of-the-art remote sensing. Built on the shoulders of the open-source geospatial community, it can process high resolution optical, multispectral and radar images at the terabyte scale. A wide variety of applications are available: from ortho-rectification or pansharpening, all the way to classification, SAR processing, and much more!
After the “What is NDVI?” post I decided to create a Python Script that solves the NDVI. This script works with a *.tif NIR band and a *.tif RED band and gives as output a new NDVI image in *.tif format. Read More..
NDVI or Normalized Difference Vegetation Index is a simple graphical indicator that can be used to analyze remote sensing measurements, typically but not necessarily from a space platform, and assess whether the target being observed contains live green vegetation or not. Read More..
A time zone is a region that observes a uniform standard time for legal, commercial, and social purposes. Time zones tend to follow the boundaries of countries and their subdivisions because it is convenient for areas in close commercial or other communication to keep the same time. Read More..
Hello world!! In this post you are going to take a look how to create vintage maps. Everyone would like to have one, so why shouldn’t you make it on your own? At first you will need to download QGIS from the official site. It’s for all OS’s (Linux, Windows, Mac OS). QGIS is a free and open source GIS. Read More..
GRASS GIS, commonly referred to as GRASS (Geographic Resources Analysis Support System), is a free and open source Geographic Information System (GIS) software suite used for geospatial data management and analysis, image processing, graphics and maps production, spatial modeling, and visualization.

A few months ago, in Shenzhen, China, a huge disaster happened. Shenzhen is in the south of China. Dust and ashes can be seen rising from the buildings collapsing as the landslide rushes down a hill. The death toll is 69 with 8 persons reported missing. It was an industrial accident due to human negligence rather than a natural disaster. The local police had arrested some of the people involved in the irregularities of the huge waste dump which was built up in previous two years. Read More..
The new release of QGIS is here. The new version 2.14 “Essen” was the host city that the developers meet ups in October 2012 and 2014.
This version is an LTS candidate (Long Term Release). LTR releases will be supported with backported bug fixes for one year, and will be in permanent feature freeze (i.e. no new features will be added, only bug fixes and trivial updates). Read More..
