Thanks, a quick glance makes me think Kepler is a layer on top of MapLibre GL. Good looking tools, but not professional GIS tools.

I’ll take a closer look. Really what I’m after is a native GIS renderer, like QGIS has, or ArcGIS that are part of a process to allow high fidelity map production.

Professional maps have legal and scientific meaning. With Kepler and MapLibre I see pretty pictures.
