Mmm, 100Mb (both as gpkg and shp and 65Mb as zipped shp. Are there any shrinking pills (algo's) available for those? Else maybe make it an alternative download? Though that complicates stuff probably. Googling about d3js and timezones (hoping the Math-people maybe had better idea's), I found: https://bl.ocks.org/mbostock/9234731/1ed485516e30474ad75ec115c928bc175683ae58 pointing to http://efele.net/maps/tz/world/tz_world_mp.zip which is a lot smaller (but lacks the buffer into the sea/water). Ah, no longer maintained: http://efele.net/maps/tz/ :-( Regards, Richard Duivenvoorde _______________________________________________ QGIS-Developer mailing list [email protected] List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer
