Vertical exaggeration

When adding a line and then creating a profile, I wish there was a feature to set the vertical to horizontal scale. I am using CalTopo for my geology major courses at university and it works quite well for many things including stream profiles, and drainage basin calculations. However, it severely lacks in the "cross section" or profile creating feature. It works quite well for what it does, but the vertical exaggeration causes a load of problems that make it impossible to use for geology. Geologists make cross sections in 1:1 vertical to horizontal scale. Meaning that the distance vertically should be the same distance horizontally. Example: 1 inch vertically is 1000 feet in scale. The cross section should also show 1 inch horizontally to be 1000 feet in scale. The lowest I've been able to get it is down to 1.5x vertical exaggeration. Please fix this and allow us to set the vertical to horizontal exaggeration! It will be so much more useful!

    Noted, and I agree that it's a weak point. I do plan to improve the profile feature, but it probably won't happen until late summer at the earliest.

    I know it's not exactly what you're asking for, but with a pro subscription you can set the sampling interval for the profile and then export the results to CSV. Then you can make your own graph using a spreadsheet program that looks exactly the way you want.
