Frequently Asked Questions
How does City Roads render Seattle roads?
City Roads pulls raw street geometries from OpenStreetMap using the Overpass API or pre-indexed protobuf graphs, rendering them in real time on a high-performance WebGL canvas.
Can I export high-resolution posters of Seattle?
Yes! The interactive viewer allows selecting custom background paper hues, ink colors, and exporting vector SVG (infinitely scalable) or print-quality PNG raster snapshots.
Is commercial use permitted?
Map geometries are licensed under the Open Database License (ODbL) by OpenStreetMap contributors. You are free to print, plot, and share visualizations with appropriate OSM credit.
