I have a bunch (think 400+) scanned old portions of maps that are in .cal format, apparently a CALS type raster format. I am able to open them in Autocad map 3d, but Arcmap does not recognize them. I'd like to (eventually) get them in a GIS, but not sure how to batch convert .cal to something more appropriate to work with in Arcmap. Hope this is the right place to ask. Thanks
