Esri JavaScript API - Interactions with Open Source tech in the JavaScript world

Fabien will give a short talk about Esri JavaScript API 4.x - Interactions with Open Source technology in the JavaScript world.

Fabien will also briefly talk to us about the GDAL Barn Raising fundraising which is happening ( http://gdalbarn.com ).
This is addressing some interesting challenges currently faced by users and of GDAL, PROJ and libgeotiff:

• The dreaded ad hoc CSV databases in PROJ_LIB and GDAL_DATA are frustrating for users, pose challenges for developers, and impede interoperability of definitions.
• GDAL and PROJ are missing OGC WKT2 support.
• PROJ 5.0+ no longer requires datum transformation pivots through WGS84, which can introduce errors of up to 2m, but the rest of the tools do not take advantage of it.
