To perform the most accurate georeferencing, the document will need to have some type of geographic coordinate grid. If the map or image does not have a geographic coordinate grid, but has other features that can be geographically located (control points), then a rubber sheet can be performed.
Rubber sheeting is the process of taking a number of control points and matching them with accurate geographic locations. The image is then transformed and can be overlaid with other georeferenced data.
After maps have been geo-referenced, Esri .shp or other vector indexes are created; in addition LAND INFO can create metadata based off the legend/marginalia of the map documents.
