After explaining all the theoretic aspects of type, we will now introduce you to the process of computer-based lettering
of map names. When you start lettering your map, you will have already imported your data into a DTP drawing program. More information on how to handle your data in order to reach this step can be found in "Handling GIS data"
as part of the Intermediate module.
DTP drawing programs usually offer a range of different type options. In most of the programs, you will find a palette of
basic type settings as font-family, font-size, letter- and line-spacing ,
kerning,
tracking and baseline adjustment.
In case you are using postscript font you will find options for special effects like hollowed fonts, shaded fonts, 3D-fonts etc. It is important to know that
effects made on TrueType fonts are not able to be printed on a laser illuminator. On the other hand, postscript fonts may
be transformed into pieces of signs. After this, its form can be changed to your own needs. But there is more to think about
if its use is to make sense in cartography.
For label positioning, many DTP drawing programs provide different standard transformation tools like rotation, translation, distorting and mirroring. In some programs, you will find a special lettering tool which is very useful for cartographers: aligning text along a path. It is used e.g. to easily label rivers or high mountain ranges.
Another important lettering effect for cartographers is the possibility to clear the details around the label to ensure an appropriate legibility. There are two ways to realize this:
