Which is more accurate for indexes? It seems they change the maps ALOT depending on which you choose.&nbsp;

Is the area given in Equal spacing correspond with what’s going on in the field reflectance wise? For instance reflectance X to Y is yellow with 2.0 Hectares of area, is that actually true, and does it sync up with the equal area position info? &nbsp;

Hello Thomas,

Those parameters are just to define the representation of the index map.The values should not change.

Indeed, when you go from one representation to another, the min/max of the classes change too.

The article explains the meaning of those settings: [Menu View \> Index Calculator \> Sidebar \> 4. Color Maps and Prescription](http://Menu%20View%20%3E%20Index%20Calculator%20%3E%20Sidebar%20%3E%204.%20Color%20Maps%20and%20Prescription)

Regards.
