[QGIS-Developer] Vector tiles

[Even Rouault]

Tom,

This has been somehow discussed in https://trac.osgeo.org/gdal/ticket/7228
Bottom line is that the multi-scale approach of vector tiles doesn't fit well with the 
traditional scale-agnostic vector layer approach. So somehow you need to assign each 
vector tile zoom level to a cartographic scale range.

Another thing not covered by the OGR MVT driver is the merging of the geometries of 
identical linear and area features split over several tiles (when iterating over a high zoom 
level with many tiles, doing that would have serious memory & processing time 
implications. When doing that for typical display purposes when you have just a few tiles 
opened at a time, this is something that can be done more reasonably).

The OGR MVT driver will appear in GDAL 2.3.0, expected to be release around May.
