# Software options

Spectral analysis can be performed in a wide range of software packages, ranging from black box interfaces, to more adaptable implementations. In many cases, image processing and GIS software will be implementing the same algorithms, so software choice is not always the most important consideration. 

However, we have provided a list below as a starting point. It is by no means exhaustive. 

* GIS 
  * Esri ArcGIS 
  * QGIS 
* Image processing software 
  * ENVI 
  * ERDAS
  * PCI 
  * eCOGNITION 
* Coding languages (many available modules) 
  * Python 
  * Matlab 
  * R
