See what is reachable from a place
Make location decisions with a clear travel-time boundary, right from Telegram.
Trigger
New Message Received
Triggered when your bot receives a new message in a private chat, group, or supergroup. To receive every message in a group, Privacy Mode must be disabled for the bot in BotFather.
Action
Get Isochrone
Tool to compute isochrone polygons for a given point. Use when you need to determine areas reachable within time or distance constraints.
Why this helps
Estimating whether a place is close enough by eye can create uncertainty and repeated map checking.
- Check a defined travel-time or distance area around a place.
- Answer location questions without manually exploring a map.
- Make venue and meeting choices with a consistent boundary.
Setup
Build it in a few focused steps.
- 1Connect Telegram and GraphHopper to Notis once through the portal.
- 2Create an automation in the portal or ask Notis conversationally.
- 3Write one instruction asking Notis to use GraphHopper's isochrone action when a Telegram message gives a point and time or distance limit, then summarize the reachable area.
- 4Choose Telegram New Message Received as the trigger and choose the run-report channel.
- 5Test with a real location and a clear time or distance limit.
Questions about this workflow
What does an isochrone tell me?
It represents the area reachable from a point within a specified travel-time or distance constraint.
Can it choose a venue for me?
It can help assess reachable areas. The prompt should state the location and limit to evaluate.
