BGT tiles

[Diaaz]

It looks like the BGT-tiles are available for Amsterdam only. When will the rest of the Netherlands be published?

@Diaaz sorry late reaction but this is something that is discussed at the moment. At the moment I can't say what will happen and when. A bit vague but I wouldn't expect anything the next few months anyway..

[Diaaz]

@jeroenPDOK thanks for your response. Can you publish a how-to guide, so we can generate the tiles ourselves for the time being?

[J-kad]

@Diaaz we already did, see https://github.com/PDOK/vectortiles-bgt-brt

@jeroenPDOK I cannot find any information about how to generate tiles of a specific area. Are the tiles generated from public data-endpoints?

@emacgillavry perhaps you can give some more details?

@Diaaz we created the vector tiles from BRT and BGT data (see https://github.com/PDOK/vectortiles-bgt-brt#source-data-per-zoom-level).

1. Load the data into PostGIS using NLExtract (see https://github.com/nlextract/NLExtract)
2. Convert the data into the right structure using SQL (see https://github.com/PDOK/visdata/tree/master/sql)
3. Export the data to GeoJSON using ogr2ogr (see https://github.com/PDOK/visdata/tree/master/generate_geojson).
4. Create MVT files from the GeoJSON using Tippecanoe (see https://github.com/PDOK/visdata/tree/master/generate_mvt)

We're happy to help you out should you require a production setup for vector tiles!

@emacgillavry Thanks for the details. Do you know if it's possible to generate RD tiles?

[emacgillavry]

According to the MVT standard, tiles don't know about projections. Hence, support for RD should be ok. Possibly fake PostGIS by setting the projection using ST_SetSRID to 3857, while maintaining the coordinates in RD. Caveat emptor: haven't actually tested this.
