The digitization is a bit different from digitalization. Digitalization is a process in which things are shift to modern technological tools but the term is used specifically in modern mapping software e.g ArcMap, GIS, AutoCAD or mechanical desktop etc. for mapping and cartography.
I work in a Govt. organization where I use ArcMap to draw maps. My basic duty is to convert the manual maps to digitized maps. It means I digitize the maps with roads, canals and other ground features which were not drawn in manual maps. I use different tools to draw a better maps.
ArcMap is very advanced software in which there are lot of tools. We can hardly know all of them. ArcMap can be used for various fields of life e.g engineering of all kinds, Geography of the world, All kinds of mapping and cartography etc.
There is a great toolbox in ArcMap. We normally use line, Point, Polygon features in this software to digitize maps but it is a ocean of tools with vast field of works to utilize them.
