The clear stuff is expensive, so we put as many overlays as we can on each sheet. Other folks don't have the stuff to print a nice crisp copy of the PDF files. To find out which tools are available visit the Map Tools Products page. If the scale you need isn't here, follow these instructions to create your own scale These tools were designed using Adobe Illustrator on a Macintosh. The PDF files can be opened and edited in Illustrator running either on a Mac or Windows platform.
Maps come in all different scales.
You may find that you need other scales. To scale an existing map tool to a different scale you should select a tool that is close to the scale you need, and then determine how much to scale it by. Always double check your results against the map to make sure you get the correct results. John Carnes, 1998. All rights reserved.
