Re: 1 to 1 Zoom



1:1 simply means for every file pixel will display with every one screen pixel. Its a factor of your file spatial resolution and your screen resolution. Why you are seeing changes in scale factor as you change the resolution of the imagery example.


For any tool you are unsure about, i suggest looking at that relavent section in the help documentation and/or Wiki. Detailed explanation found here:
