But what I observe from the shell-output is, that z-levels < ```-Z``` are also processed, while they luckily don´t get written to the mbtiles file.\r\nLooks to me like this makes the processing time a lot longer then necessary.\r\nIs there a way to completly avoid  0 to ```-Z``` levels.\r\n\r\nNevertheless I wanted to thank you for your work. i'm so glad that I found tippecanoe."},"comment":{"url":"https://api.github.com/repos/mapbox/tippecanoe/issues/comments/268038500","html_url":"https://github.com/mapbox/tippecanoe/issues/340#issuecomment-268038500","issue_url":"https://api.github.com/repos/mapbox/tippecanoe/issues/340","id":268038500,"user":{"login":"ericfischer","id":1951835,"avatar_url":"https://avatars.githubusercontent.com/u/1951835?v=3","gravatar_id":"","url":"https://api.github.com/users/ericfischer","html_url":"https://github.com/ericfischer","followers_url":"https://api.github.com/users/ericfischer/followers","following_url":"https://api.github.com/users/ericfischer/following{/other_user}","gists_url":"https://api.github.com/users/ericfischer/gists{/gist_id}","starred_url":"https://api.github.com/users/ericfischer/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ericfischer/subscriptions","organizations_url":"https://api.github.com/users/ericfischer/orgs","repos_url":"https://api.github.com/users/ericfischer/repos","events_url":"https://api.github.com/users/ericfischer/events{/privacy}","received_events_url":"https://api.github.com/users/ericfischer/received_events","type":"User","site_admin":false},"created_at":"2016-12-19T18:22:55Z","updated_at":"2016-12-19T18:22:55Z","body":"Thanks for suggesting the improvement!"}}
