I have a scanned copy of a 7.5 minute series topographic map and want
to use it in conjunction with DeedMapper. How do I set the image
options to get it into sync with my plots? Is there a standard
feet/inch - dots per inch for these maps?
You'd need to see what the manufacturer states as the dots per inch
factor. You can also just experiment with different values from 200 dpi on
upward to 1200. If you can identify two points on the map that are a mile
apart you can enter a deed with a one mile long line and adjust the scale
until everything fits.
I also purchased the road & stream map for the same area. Can I
the the topo, stream maps and my plots at the same time?
Yes, a project can have both images and our maps. Be aware that we
give priority to the image. In other words, they reside 'on top of' any
maps you have.
