I recently started creating lake signs for locations all over the US. Basically just the name of the lake and the profile of the lake itself. I have been struggling to find a good source for clean vector files of these lakes though. Any suggestions? Thank You!
Try looking for a Topo map of the area. I know that at one point you used be able to download them from the USGS.
I started looking into this and it's probably a viable option. You can export map data to an OSM file, then use a desktop app or a command-line utility to convert it to SVG, which can then be imported into Illustrator.You may be able to get vector information from OpenStreetMap.
I think google earth used to have it in the options sections for view mode..
