I have access to tiff files of a whole state. I want to know what would be the ideal format to change the tiffs to so i can place them in a dwg by using the image manager.

That way i can xref the quad map into dwgs i need location maps for and other uses. to get info.

These .tif images are scans of the original quad maps? Or are you talking aerials.

I'm doing something similar rigth now only I'm using FEMA maps. My procedure;
1: open new dwg
2: query section lines streets and other topo features for existing dwgs
3: insert image near line work with generic scale.
4: select two points on both the image and the line work which represent  the same place geographically.
5: move scale and rotate the image to match line work.
6: discard line work save the dwg.

the image is now positioned realitive to SP in that dwg.

later I'll created a new image that is georeferenced.
