The ENVI Analytics Symposium is happening again August 23-24 this year in Boulder, CO:

The 2016 ENVI Analytics Symposium (EAS) continues its exploration of remote sensing and Big Data analytics around the theme of geospatial signatures to analytical insights.

Though I don’t use ENVI at all, remote sensing is still interesting to me and I would be interested in how this community is using “Big Data analytics”.
