Micro Data Service

Hosts vector tiles to be used in conjuction with the OSM Tasking Manager.

Install

$ npm install

Quickstart

$ npm start

Create Vector tiles

Using tippecanoe you can generate Vector Tiles based on your GeoJSON.

Log into server

$ ssh [email protected]

You will be adding the Vector Tiles .mbtiles inside the /data folder.

Download new data

$ cd micro-data-service/data
$ wget https://raw.githubusercontent.com/osmottawa/imports/master/CSDraveurs/CSD-schools.json

Convert GeoJSON Point to Vector Tile

# Zoom 0 to 18
tippecanoe \
    --output=$SOURCE.mbtiles \
    --force \
    --base-zoom 0 \
    --no-feature-limit \
    --no-tile-size-limit \
    --minimum-zoom 0 \
    --maximum-zoom 18 \
    --buffer 0 \
    $SOURCE.geojson

Restart the server.

$ docker-compose restart

You should now see your new dataset in the JSON.
