I have paid a GIS consultant to create detailed aerial maps for use in my business, using some specialized GIS software. We now want to take "snapshots" of certain sections of the maps, to share with certain of my associates. We're trying to do that by creating PDF's, which seem to work when we create relatively manageable (under 50KB) size PDF's, but we actually need to create some maps which I believe will be 0.5 GB to 1.0 GB each in PDF format - but when we try to create PDF's that large, it doesn't work. Is there a file size limit with Reader? Can I upgrade to some form of Adobe Acrobat that doesn't have a file size limit? Any other ideas? Thanks!
