It could be stroed in the avscience database as either an integer or a cardinal direction. I recommend an integer, for consistency with the aspect field. But to be retro-compliant, we would need to change the avscience db how the old data is stored; or create a new column for the 0-360 value."},"comment":{"url":"https://api.github.com/repos/jimurl/Snowpilot/issues/comments/221760325","html_url":"https://github.com/jimurl/Snowpilot/issues/11#issuecomment-221760325","issue_url":"https://api.github.com/repos/jimurl/Snowpilot/issues/11","id":221760325,"user":{"login":"jimurl","id":7062347,"avatar_url":"https://avatars.githubusercontent.com/u/7062347?v=3","gravatar_id":"","url":"https://api.github.com/users/jimurl","html_url":"https://github.com/jimurl","followers_url":"https://api.github.com/users/jimurl/followers","following_url":"https://api.github.com/users/jimurl/following{/other_user}","gists_url":"https://api.github.com/users/jimurl/gists{/gist_id}","starred_url":"https://api.github.com/users/jimurl/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/jimurl/subscriptions","organizations_url":"https://api.github.com/users/jimurl/orgs","repos_url":"https://api.github.com/users/jimurl/repos","events_url":"https://api.github.com/users/jimurl/events{/privacy}","received_events_url":"https://api.github.com/users/jimurl/received_events","type":"User","site_admin":false},"created_at":"2016-05-26T02:16:57Z","updated_at":"2016-05-26T02:16:57Z","body":"... But now, I think this is fine. It appears that both types ( N<S<E<W + intermediates and integer 0-360) are CAAML-compliant ( ~ line 800 in CAAML V5...xsd).\r\n\r\nBuyt, to my mind, more importantly, wind direction does not lend itself to highly accurate measurement in the field by humans. For one, it is changable; and for another, its hard for a person, even with a compass and using best measurement techniques, to regularly detect wind direction changes of 22.5 degree or less increments, which is where using degree mesurements might be beneficial. IN measuring slope aspect, it doesn't change, and a compass can give a good observer can give accuracy to just a few degrees., so the 0-360 is more justified"}}
