- 4%Of the Atlas
- 100%Convention stated
100% of this source's records state their own azimuth convention in the published data. Where a convention is not stated the Atlas infers it from the source's documented practice and records that it did so — which is why every row keeps a link back to the map it came from, and why a measurement that matters should be checked against that map.
