I'm trying to view the same file in 2 buffers, one at normal scale and the other zoomed out, to see the whole buffer (as in notepad++ document map: http://notepad-plus-plus.org/assets/images/docMap.png ).
Is there any way visit the same file in different buffers, so that each buffer can have different settings?

Much better to use the multiple buffer feature of emacs. If you are editing the first file and want to start editing the second file, simply use the hot key C-x C-f or the menu selection File->Open File to start the second file. The second file is loaded into its own buffer.
Each Emacs window displays one Emacs buffer at any time. A single buffer may appear in more than one window; if it does, any changes in its text are displayed in all the windows where it appears. But the windows showing the same buffer can show different parts of it, because each window has its own value of point.
This is because Emacs tracks buffer positions using that data type. For typical 64-bit machines, this maximum buffer size is 2^{61} - 2 bytes, or about 2 EiB. For typical 32-bit machines, the maximum is usually 2^{29} - 2 bytes, or about 512 MiB.
The number of buffers you can have really has no limit. Most of the time, only one or two buffers are displayed, but even if you can't see them, all the buffers you create in an Emacs session are still active. You can think of them as a stack of pages, with the one being displayed as the top page.
Try M-x clone-indirect-buffer (or M-x clone-indirect-buffer-other-window aka C-x 4 c), and then you can set the font in one of the buffers real small.
You can make the font smaller or larger in a buffer with the bindings C-x C-- or C-x C-+, which run the command text-scale-adjust.
There was a mode that someone made that did this splitting/shrinking automatically, but I'm unable to find it.

You want to install the minimap package (it's in GNU ELPA) which does just that.
