Idea, the 6 inch photos are not even noticable as better than 12 inch until you
zoom into under 1:1000 or more. Even though the compressed ECWs are about
8GB, the server seems pretty fast. I will think about trying at least two
levels and see how that works. Maybe a 3 foot and 2
foot.</FONT></SPAN></DIV>

that ECW is pretty excessive resource-wise. Just make several different
quality outputs of your ECW and use MINSCALE and MAXSCALE in the map file to
produce the one you want at a given scale. I know when I started using JP2 I
quickly decided on MINSCALE MAXSCALE implementation for speed concerns and if
done with enough levels, you really shouldn’t
notice.<o:p></o:p></SPAN></FONT></P>

are not "see through" so if you have an ECW that covers the City, mapserver
will fill the rest of the image with a color (typically white).
Transparency comes into play, because if you serve the image as a PNG or GIF
then the "white" becomes "see through" (aka "transparent").<BR><BR>This

but JPG acts the same way. My question is why does transparency come
into play when I do not want to see under the image, I want to see beyond
the extent of the image. For example the image is 1 mile by 1 mile and
it still covers up the whole county. Is that because the mapserver
still thinks the image is county-wide?</SPAN></FONT><o:p></o:p></P></DIV>
