Two symbol libraries were created. The first one is a set of symbols for description of map orientation (compass roses and north arrows) with correct national (in this case Czech) description. The second one is a set of symbols for description of CBRN (chemical, biological, radiological, and nuclear) threats and another CBRN issues. The TrueType font files are used as symbol libraries in various ESRI products. The font libraries created in this form are easily transferable between various operating systems and GIS programs and also can be easily converted into various different vector graphics formats. The whole process of font creation has taken place under Linux environment. Fortunately main programs used in this process are multiplatform and could be used under Linux, MS Windows and other various computer operating was part of Ubuntu repository and it was obtained free of charge. systems.
