OpenMapTile Vector Tiles

This post outlines how you could use the OpenMapTiles project to create a custom OpenStreetMap extract of vector tiles for use in our maps. We use so little credits on Mapbox that this has not been utilized.

In Ubunutu 18.04

git clone https://github.com/openmaptiles/openmaptiles.git
cd openmaptiles
./quickstart.sh

Delete the albania osm file in the data folder and replace with the latest Ohio data from http://download.geofabrik.de
Move this file into the data folder
Create a docker-compose-config.yml file in the same directory as follows:

version: "2"
services:
  generate-vectortiles:
    environment:
      BBOX: "-84.8202, 38.4031, -80.5187, 41.9775"
      OSM_MAX_TIMESTAMP: "2019-04-04"
      OSM_AREA_NAME: "ohio"
      MIN_ZOOM: 0
      MAX_ZOOM: 14

./quickstart.sh the name you gave in the OSM_AREA_NAME so ./quickstart.sh ohio

Copy the tiles.mbtiles to Windows

Unpack the mbtiles to a folder of vector tiles with https://github.com/phiphou/mbtiles2ungzpbf

Tried on windows and failed

docker-compose up -d postgres

docker-compose run import-water
docker-compose run import-natural-earth
docker-compose run import-lakelines
docker-compose run import-osmborder

Install OpenMapTiles-Tools

docker run -v data/ohio-latest.osm.pbf openmaptiles/openmaptiles-tools

docker-compose run --rm openmaptiles-tools generate-tm2source openmaptiles.yaml --host="postgres" --port=5432 --database="openmaptiles" --user="openmaptiles" --password="openmaptiles" > build/openmaptiles.tm2source/data.yml

docker-compose run --rm openmaptiles-tools generate-imposm3 openmaptiles.yaml > build/mapping.yaml

These two files mapping.yaml and data.yaml need converted to UTF8 which can be done in Notepad or Notepad++

docker-compose run --rm openmaptiles-tools generate-sql openmaptiles.yaml > build/tileset.sql

Import the ohio-latest.osm.pbf

docker-compose run import-osm`

This should show that it is importing from the ohio file, and not the default albania file.

Generate the mbtiles vector tiles

docker-compose run generate-vectortiles

ERROR - z(numeric) does not exist - Just run on an Ubuntu droplet
