[Geo4All] [geoforall-ab] Ideas invited from "Geo for All" community for Global Week to help demonstrate and raise awareness of "geo" in education at UNESCO

Hi all,

Venka is exactly right about Cesium's license; we specifically selected Apache 2.0 to allow broad use.

Patrick - it is so nice to be in direct contact with you!  Are you open to discussing collaboration between Web World Wind and the Cesium team?  Such a collaboration could potentially save years of development effort for Web World Wind, demonstrate Cesium's community commitment, and help us both serve the open-source geospatial community even more.

Have a great weekend!

Patrick

As far as the OSGeo projects are concerned, as noted in [1], the foundation's projects are all freely available and useable under an Open Source Initiative certified [2] open source license.

As you can see in [2] Apache License 2.0 is one of the most popular among the licenses certified by OSI.

Cesium itself is available under Apache 2.0 license [3] and I see no issue in using it in OSGeo related software development and outreach activities.

Infact, there were several interesting presentations based on Cesium at the recent FOSS4G-Bonn [4]
