I very much doubt it. Vertical accuracy of GPS is by design tradeoff worse than horizontal accuracy, which itself is generally 3m unless your GPS costs thousands of euros. A 4-5m altitude error is fine for hillwalking, but not for lake water depth. _______________________________________________ Talk-ie mailing list [email protected] https://lists.openstreetmap.org/listinfo/talk-ie
