my tif image data type is float( my data is in between -1 to +1). I want to convert it into 8bit unsigned integer.
I used ErdasImagine import tool to do this, while conveting into img also.
but in the out put image the data is only shows 0 and 1.
what is the problem. I want to convert -1 as 0 and +1 as 255.
How can I do this in erdas and arcGIS
