Add network to transport layer ( #1158 )
...
Closes #1153
This PR populates the existing `network_type` field in the route table with highway route network information, using the most important value in cases of concurrencies. In order to expose this value, two files `network_type.sql` and `update_route_member.sql` were moved from the `transportation_name` layer to the `transportation` layer.
Below is a representative zoom level 6 with motorways only shown for `us-interstate` network types. This sample was generated from this PR using a [custom branch](https://github.com/ZeLonewolf/openstreetmap-americana/tree/selective-highway-zoom ) of openstreetmap-americana. This provides a simplified rendering of the highway network which excludes many minor motorway roads and sections.
Below is zoom level 6 on the current [openstreetmap-americana](https://zelonewolf.github.io/openstreetmap-americana/#6/42.148/-73.712 ). Notice the many additional stubs, motorway islands, and minor routes which are present. Instead of rendering `highway=trunk` to make this network look nice, we can instead suppress non-interstate roads and withhold motorway+trunk rendering to a closer zoom:

Fix transportation road segments disconnection ( #1109 )
...
To avoid discontinuous transportation lines between zooms 9 and 11.
- Originally limit geometry by length for z9 - z11 (`ST_Length(geometry) > ZRes(11)`)
- highway z9 to z11 was generalized during import-osm
- now just create a filtered and generalized z11 table
- then merge segments in the same way as from (full-featured) osm_highway_linestring and used this merged z11 for mat.view z10 and z9
Close #1107

adding brunnel into z<9 ( #1038 )
...
Following https://github.com/openmaptiles/openmaptiles/pull/1027 , solving https://github.com/openmaptiles/openmaptiles/issues/999 .
Adding brunnel attributes to merge tables of `transportation` layer, now it is possible to style/filter tunnels, bridges and fords in all zoom levels. Tested on Switzerland and Europe. Changes in generation speed and filesize minimal.
