I am trying to create a base map suitable for overlaying data that is in SRS EPSG:4326 using CartoDB following the projections tutorial. I have other projections working, but not one for this.
SELECT cartodb_id, ST_Transform(the_geom, 4326) AS the_geom_webmercator FROM world_borders_hd
It does not seem to return any geometries plotted in the tiles.
From a comment on the CartoDB academy issue I posted, I presume this is something to do with a scale that needs to be applied in the transformation from degrees to meters.
Can anyone advise me what I need to do in the SQL to get a zoom 0 tile that would look like this?
