The problem I am having on my phone (Samsung S5) is that when I zoom way out so I see all these vectors, things get slow again most likely because it's just too many vectors for my phone to handle well.  I wonder if there's anything we can do about this, such as clip down the area that these vectors are plotted at.  Could this be done in WindNinja?  Possibly Natalie could revisit this code in WindNinja to see what we are doing and if we can clip it smaller...\r\nAnother possible speed up could be to not plot the blue vectors around the border, because these are essentially NO_DATA values that occurred due to reprojection."},"comment":{"url":"https://api.github.com/repos/firelab/windninja-mobile/issues/comments/143898400","html_url":"https://github.com/firelab/windninja-mobile/issues/27#issuecomment-143898400","issue_url":"https://api.github.com/repos/firelab/windninja-mobile/issues/27","id":143898400,"user":{"login":"fspataro","id":5933821,"avatar_url":"https://avatars.githubusercontent.com/u/5933821?v=3","gravatar_id":"","url":"https://api.github.com/users/fspataro","html_url":"https://github.com/fspataro","followers_url":"https://api.github.com/users/fspataro/followers","following_url":"https://api.github.com/users/fspataro/following{/other_user}","gists_url":"https://api.github.com/users/fspataro/gists{/gist_id}","starred_url":"https://api.github.com/users/fspataro/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/fspataro/subscriptions","organizations_url":"https://api.github.com/users/fspataro/orgs","repos_url":"https://api.github.com/users/fspataro/repos","events_url":"https://api.github.com/users/fspataro/events{/privacy}","received_events_url":"https://api.github.com/users/fspataro/received_events","type":"User","site_admin":false},"created_at":"2015-09-28T23:09:55Z","updated_at":"2015-09-28T23:09:55Z","body":"Below is picture of the \"weather\" vs \"run\".  The yellow dots are \"0\" which could easily be excluded but that only takes out about 2k of the 7k dots.  That still leaves quite a lot especially given the extent of the run.  Should I double (or more?) the extent of the run and clip just those points?  \r\n\r\n![image](https://cloud.githubusercontent.com/assets/5933821/10151281/5c9d5696-6603-11e5-9c67-8548eac5fa9a.png)\r\n"}}
