Mountain hiking association asked me to monitor local hiking relations from edits done by other mappers. I wrote this script which generates an html page with OSM changeset involving daily changes. It is feeded by overpass-turbo query, like this, so you can customize which OSM objects to monitor.

steps

The mentioned monitor script will:

• extract relations modified in the last 24h and tagged operator=”CAI” in area provided as argument
• filter useful informations
• format an html file with OSM, Achavi and OSMcha links

automate runs

Of course it can be run periodically using crontab. To set a daily run, just execute
$ crontab -e
add a line like below, customizing your script path:
0 0 * * * /home/pi/scripts/monitor.sh  » /dev/null 2>&1

telegram

My instance include a telegram service fired when a changeset list is written. I use telegram-cli with the following line in script:
echo “msg $CHANNEL $MESSAGE”; echo “safe_quit” | /home/pi/apps/tg/bin/telegram-cli -W

Just add telegram CHANNEL and MESSAGE variables and insert the line inside $CHAN==0 else if

TODO

Fix area names which include spaces, ie “Cividale del Friuli”
