Step 2: How to geo-reference the map you just scanned (put your scan into GIS coordinates) so you can use it as a backdrop for your digitizing.

Step 3: How to create a blank GIS map to digitize into.

Step 4: How to create a donut polygon that will give you a crisp professional looking border for your map.

Step 5: How to set up your digitizing environment so that lines you digitize automatically join with neighboring lines
