The GUI for each tool is logical and well sized. The classification tools are simple to use. Overall a well designed imagery analysis tool set. Simple to change symbology.

I think it is the mainstream software for remote sensing analyst. The thing I like the most with ERDAS IMAGINE is its capability of performing almost all the processings you can find from remote sensing books, such as calibration, classification, and accuracy assessment.

I was pleasantly surprised when I started using ERDAS Imagine, having previously used ArcGIS and IDRISI in university for all remote sensing. ERDAS Imagine is specifically designed for remote sensing purposes, and as such one of its main benefits is the speed at which it can handle large raster files. Other favourites within the software are the Spatial Modeller function which provides a platform to build your own queries and use again later - really helpful on repetitive tasks! Imagine provides a perfect base for the beginner to highly advanced 'remote senser' with its ample amount of tools within a highly user friendly environment (I love the ribbon interface). the help button is also very useful providing helpful run throughs of specific functions. So in summary, my best points are: - Speed - Spatial Modeller - Variety of tools and functions - User friendly - Help tool
