Cover Story: Digital maps are used daily by millions of users. Verifying the quality and consistency of route data is becoming more and more important. In this paper, we introduce a novel geospatial data analysis system that is based on road directionality. We investigate our Road Directionality Quality System (RDQS) using multiple map providers. Results from the experiments conducted show that our detection neural network can detect an arrow's position and direction in map images with >90% F1-Score. We then utilized this model to analyze map images in six different regions. Our findings show that our approach can reliably assess map quality and discover discrepancies in road directionality across different map providers. We report the percentage of discrepancies found between map providers using this approach in a proposed study area. View this paper
