Below, we show images of road networks inferred by DeepRoadMapper, our seg-mentation method, and RoadTracer in the 15 test cities. We overlay the inferredgraph (yellow) over ground truth from OpenStreetMap (blue). As in the paper, in-ferred graphs correspond to thresholds that yield 5% average Ferror for RoadTracerand our segmentation approach, and 19% Ferror for DeepRoadMapper (as it does notproduce results with lower average error). A 5 km by 5 km region is used for testingin each city; we only show a 2 km by 5 km region so that the graphs can more easilybe compared with each other on a single page.
