 Topic: Geological maps
Posted: 07.Dec.2011 at 11:54 |
Dear freinds,
I am a new user of the autocad.
I am going to scan few geological maps which are in 1:20000 scale with different latitudes and longitudes one after the other. Then I wish to digitize them and position those maps as per the latitudes and longitudes in any scale I need (1:100,000). Is it possible to have all those maps bundled together in a single larger map showing common lat and long? Plz help me with the procedure.
Regards,

I wouldn't scan them if I were you. The file size just for one geological map will be quite high but to do several and then try to edit them in one drawing will most likely crash your system.
I'm pretty sure you can download USGS maps in a DWG format.

Dear John,
I am contemplating scanning of a single contour line (may be oil-water contact contour) in each of the scanned map. Moreover, sir, I have not more than 50 of such maps and most of them are in A4 size excepting few which are in A3. besides I have access to these hard copies only. Help!!

Then there doesn't seem to be a problem with your proposed methodology. Go for it.

You have already outlined the procedure you are going to follow. It sounds like it will work. I don't think I need to fly to India and hold your hand while you do it. So, what further information do you need?
Sleep? I've been up since 3:30 a.m. I don't require much sleep. Five hours max is good enough.

Scan them individually then bring them all into one drawing as a series of xrefs would create the least amount of drag on your system. Sync each scan, one to the other, using the Align command.
You may reply if your fingers still function.
