ILWIS pixel value IN SOFTWARE AND SOMETIMES NOT LIKE DIFFERENT EXPECTATIONS?

Often I get asked which is actually just the beginning of complaints from friends. They complain why the satellite imagery used to be represented by a value between 0-255 (8 bits) in the software ILWIS it represented a value outside that range. I then rushed him to see the domain system in its properties (right-click the file "Map" and select "Properties"). Please note the pull-down menu selected in the field "Domain". If the folder is opened a satellite image of the domain is generally required is "IMAGE".
There are a variety of domains to open various file formats on the ILWIS software. It should be noted here that the different domain with a domain that I cover in the post about the webblog / internet. To introduce or just to remind those who forgot, I wrote the following domains range in ILWIS (I quote from ILWIS Additional Help).

VALUE. Domain system is used generally to calculate.
DISTANCE. Domain system is designed to calculate the distance. Fair meter units used.
COUNT. Domain system is designed to calculate the value undefined.
MIN1TO1. Domain system is designed to calculate a value between -1.00 to +1.00.
NILTO1. Domain system is designed to calculate a value between 0.00 to +1.00.
PERC. Domain system is designed to calculate the percent.
BYTE. This domain system to calculate the image that has a value between 0 to 255 where 0 meant no undefined.
IMAGE. This domain system for image with integer values ​​between 0-255.
NOAA. This domain system to image with an integer value between 0-1023.
RADAR. This domain system for radar image that has an integer value between 0-32767.
BOOL. This domain system for calculating a boolean value: True, False, and undefined.
Yesno. This domain system for calculating a boolean value: Yes, No, and undefined.
BIT. Domain system is used to calculate a value between 0 and 1.
STRING. Domain system is used for the column that contains text such as descriptions.
UniqueID. Domain system is used to map where each mapping unit is expected to obtain a unique ID.
COLOR. Domain system is used for color images (256 × 256 × 256 colors).
COLORCMP. Domain system is used as an output color pengompositan operation.
FlowDirection. Domain system is used to calculate the eight cardinal directions. Domain output Flow direction is useful for operations on ILWIS.
NONE. Domain system is used for tables that do not have a class or ID domain.

I hope these quotes help!
