[OSGeo-Discuss] CoverageJSON

Tue Aug 30 02:15:08 PDT 2016

Hi,

just humble suggestion: you can make this to OSGeo Community standard, like
TMS [1] was at it's time and get more publicity and possible more
collaborators to the project. Promote and colaborate via standards mailing
list [2]

btw: what is the mimetype, we shall stick to? (OGC WebProcessingService and
others need one single clear mimeType)

Cheers

J
