My tif image data type is float (i.e. my data is between -1 to +1) and I want to convert it into 8bit unsigned integer.
I used ERDAS IMAGINE import tool to do this, while converting it into img also.
However, in the output image the data is only shows 0 and 1.
I want to convert -1 as 0 and +1 as 255.
How can I do this in ERDAS IMAGINE and ArcGIS for Desktop?
