Scanning is the first step, and is the common practice of taking hard copy documents and converting them to a raster image
Georeferencing is then accomplished through a process of rubbersheeting the 2D image in lacking a coordinate system to a 3D real world coordinate system.
Vectorization can then occur where raster pixels in the image are converted to traditional GIS vector objects. Once this process is accomplished; attribution, spatial analysis and classification of the data is possible.
Finally, through web-based mapping technology the data can be shared to a wider user group that may need to view the data without having to have a direct copy of it, or the software used to manage it.
