Scale, format and location

Scale, format and location depend on each other. Even if the scale and the location are determined by the decision of the topic, further corrections of these three parameters may make sense after the analysis and the map concept phases. Which parameter should possibly be changed or is of priority depends on the purpose the map should have later-on. However, at most only two of the three parameters can be changed (Hochrein 1986). If the decisions are also set, the basemap can be equipped and the map projection can be chosen.
