Re: creating a map of the united states

I'm not sure if this is what you want, but have you looked at the
source code? of the page and how they handle assigning location to the
map so the program recognizes when the cursor is over Washington and
not Montana etc. I saved the image you referenced and opened it in
GIMP. I enlarged the to 200% so that I would have reasonable accuracy
on hitting the corners with the cursor. I checked The image
coordinates for the corners of ND were the same as the coordinates
used to describe ND in the source code. ie.
coords="171,29,220,31,225,64,169,61"
You probably get this, but for the watching world, each point
referenced is described by the number of pixels to the right of the
origin (upper left corner in this case), 171 and by the number of
pixels down, 29. This is the north west corner of ND the next pair of
numbers are the coordinates of the North east corner and so forth.
Because WA and OR and other states have irregular boundaries the
number of pairs of coordinates varies.
Now I only needed Gimp to verify that  Gimp and the browser used the
same origin (upper left corner) and the same units (pixels). If you
wanted to enlarge this map for your page or if you wanted to use a
different map then you  would need Gimp to locate each point on the
state's border needed to represent it with reasonable accuracy.
Gimp gives a direct read out of the cursor location. Look in the lower
left corner of the Image Window. Also check the units menu it defaults
to pixels (px). In the view menu of the Image window make sure "dot
for dot" is checked this will ensure wysiwig.  Gimp help seems to
indicate that the positioning from image to image is only identical at
100 %. I get identical readings at 200%. The preferences provide for
aligning the pixel count in Gimp with the screen size. The help
discusses this. Mine defaulted to the same count.
Hope this makes sense and addresses you need.
