This map makes use of Ordnance Survey's OS Vector Tile API, under their OpenData plan.
Advantages
- Provided by Ordnance Survey free of charge under their OpenData plan.
- Uses vector tiles, which are more efficient than raster (picture) tiles, so the maps tend to load faster and can be crisper.
- Includes topographic contours.
Disadvantages
- Limited to Great Britain (excludes Northern Ireland).
- More detailed maps require a paid-for subscription.
- May require OS branding to be displayed, in addition to the text attribution.
