Generalization Problems of Orienteering Maps

Abstract

Orienteering maps are special types of topographic maps. This chapter describes the generalization issues of orienteering maps, including several problems of various disciplines and different map specifications (especially foot orienteering and sprint orienteering). Some of the generalization problems are caused by the very detailed base maps (either made by stereophotogrammetry or by using laser scanning data), because the mapmakers of orienteering maps are regularly nonprofessional volunteers. Therefore, there is a high risk of creating over-detailed, illegible orienteering maps.
