This sequence will introduce tools for doing that, alongside tutorials & guidance. In addition, taking some time to lay out your model clearly is probably good for your own thinking and understanding. It's easier to do that when it's easy to explain your view, understand others', and quickly see agreements, disagreements and cruxes. In particular, we're trying to do truth seeking. Tools exist to make this experience better, but they may be underused. 1 INTRODUCTION: Hyperspectral remote sensing (HRS) is the same technologies that provide detailed spectral information for individual pixels of an image.EA involves working together remotely a lot. Hyperspectral remote sensing is an emerging, multidisciplinary field with diverse applications in Earth observation. HRS is a technology that provides spatial and spectral information simulate. It enables the identification of targets and other phenomena as the spectral information is presented on a spatial rather than point (pixel) basis. HRS is tools with many applications, such as geology, ecology, geomorphology, pedagogy, atmospheric science, and forensic science. Nowadays spectral remote sensing techniques allow monitoring of changes in the physiological state of plants with high spectral resolution.Īs such hyperspectral remote sensing technology is applied by decision makers, farmers, environmental watchers in both the private and government sectors, city planners, stock holders, and others.

The use of this sensors is still relatively costly and requires professional manpower to operate the instrument and process the data. Today, in addition to the growing number of scientific papers and conferences focusing on this technology, the hyperspectral remote sensing discipline is very active: commercial sensors are being built, orbital sensors are in advanced planning stages, national and international funds are being directed toward using this technology, and interest from the private sector increases.

The aim of this research is to provide a general and comprehensive view of the introduction of software that can be used to perform processing on hyperspectral information.

The main focus of this research is on open source and free software. Also, due to the high capabilities of MATLAB software, a special section has been shown to show the performance of this software in this research.Ģ BACKGROUND: In the application different supervised spatial-spectral classification schemes for remote sensing hyperspectral data can be applied by using chains consisting each one of a different ordering of configurable stages. The wide availability of satellite and airborne imagery available from different sources has turned remote sensing image analysis and interpretation in a very active research and work field (van der Meer et al. The most widely used commercial software tools for Geographical Information Science (GIS) and, in particular for remote sensing, are Ecognition and ENVI. Both allow to perform the most relevant tasks associated to the analysis of geospatial images such as fusion of data provided by different sensors, segmentation or classification. In the case of freely available and open source software the website currently lists 11 remote sensing software tools. Some of the free and open source software can provide more functionality than proprietary low-end GIS products (Steiniger and Bocher 2009).
One of the most complete free and open source options is GRASS GIS (Neteler et al.
