Hi Jia, Thank you for the info: I added your tutorial here: https://github.com/opengeospatial/developer-events/wiki/Open-Standards-and-Open-Source-Software-Code-Sprint#mentor-streams
Regarding the project, I suggest you describe it on this issue: https://github.com/opengeospatial/developer-events/issues/45 Cheers, Joana Dr. Joana Simoes, PhD Developer Relations | Open Geospatial Consortium (OGC) Skype: [email protected] <mailto:[email protected]> | Discord: doublebyte#8420 [email protected] <mailto:[email protected]> | ogc.org <http://ogc.org/> | @opengeospatial > On 21 Apr 2023, at 18:41, Jia Yu <[email protected]> wrote: > > Hi Joana, > > I agree with the timeslot.
