Error detection in OpenStreetMap

This repository shows an easy way to detect errors in OSM using osmlint and osm-qa-tiles

Clone the repository

git clone https://github.com/Rub21/run-osmlint.git

Install dependencies

run-osmlint$ sudo ./install.sh

Obtaining data

osmlint works with the data produced by osm-qa-tiles. You can get MBtiles data from the planet or the MBtiles data by contry

For this example I will use peru.mbtiles

Getting the bounding box for Peru

You can use the wiki for the Bbox or this page as well, use the mouse to select places you want to work on and copy the coordinates that appear within the URL. e.g

-81.462250,-18.417079,-68.542328,0.24169850

Executing the comands

To run all validators you can use the following command.

./worker.sh https://s3.amazonaws.com/mapbox/osm-qa-tiles/latest.country/peru.mbtiles.gz "[-81.462250,-18.417079,-68.542328,0.24169850]"

In case you want to run the validator separately, you can use the following commands.

wget -O /tmp/peru.mbtiles.gz https://s3.amazonaws.com/mapbox/osm-qa-tiles/latest.country/peru.mbtiles.gz
gunzip /tmp/peru.mbtiles.gz
osmlint crossinghighways --bbox="[-81.462250,-18.417079,-68.542328,0.24169850]"  /tmp/peru.mbtiles > /tmp/crossinghighways.json
python utils/merge-geojson.py /tmp/crossinghighways.json > /tmp/crossinghighways.final.json
geojson-josm-url /tmp/crossinghighways.final.json | gist -f crossinghighways.final.json

the output will be a URL gist like: https://gist.github.com/7bd40a110f8118e753e3
