Sketch maps are an intuitive way to display and communicate geographic data and an automatic processing is of great benefit for human-computer interaction. This paper presents a method for segmentation of sketch map objects as part of the sketch map understanding process. We use region-based segmentation that is robust to gaps in the drawing and can even handle open-ended streets. To evaluate this approach, we manually generated a ground truth for 20 maps and conducted a preliminary quantitative performance study.
