SYNONYMS Real-time generalization, dynamic generalization, online generalization DEFINITION Map generalization defines the process of producing maps at coarser levels-of-detail (LOD), while retaining essential characteristics of the underlying geographic information. On-the-fly generalization, then, denotes the use of automated generalization techniques in real-time. According to [1] this process creates a temporary, generalized dataset exclusively for visualization, not for storage or other

On-the-fly generalization is intimately linked to highly interactive applications of cartography such as web mapping, mobile mapping (e.g. in location-based services), and real-time decision support systems (e.g. in disaster and evacuation management) that involve multiple spatial scales. As it takes place in a highly interactive setting, the cartographic quality requirements are typically relaxed compared to traditional, high-quality paper maps. On the other hand, (near) real-time behavior is imperative.
