Abstract: This study aims to develop a method of change detection and updating for urban building features at smaller-scale maps from updated larger-scale maps. Firstly, an in-deeper and comprehensive analysis of changes between maps at different times and scales was discussed. Then, a technical framework of change extraction and updating was proposed based on the functions of map overlap and data enrichment. Finally, real-life data were used to verify the effectiveness of the proposed method, and results also showed that our method is flexible and suitable for layer-level updates.

Key words: data updating, change detection, multi-scale maps, map overlap, data enrichment
