Map where you can reach from a Slack location
Translate a travel limit into a geographic area the team can consider.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Generate isoline (isochrone/isodistance)
Tool to generate isochrone or isodistance isolines. Use when visualizing reachable areas from a point; use `id` to poll ongoing calculations.
Why this helps
Deciding whether a place is within reach often means guessing or checking many destinations one by one.
- Visualize the area reachable within a stated limit.
- Use one boundary to guide local planning.
- Reduce repeated destination-by-destination checks.
Setup
Build it in a few focused steps.
- 1Connect Slack and Geoapify to Notis once in the portal.
- 2Create an automation in the portal, or ask Notis conversationally to map reachable areas from Slack plans.
- 3Use one plain-language instruction to extract the starting location and stated time or distance limit, request a Geoapify isoline, and report the result with its source context.
- 4Select Slack Channel Message Received and choose where Notis should report runs.
- 5Test with a message containing a real start location and a clear limit.
Questions about this workflow
What details does the Slack message need?
It should include a usable starting location and a clear travel-time or distance limit.
Does the workflow need to wait for the calculation?
Some isoline calculations may continue asynchronously; Geoapify supports polling with the returned calculation ID.

Forward Geocoding
Tool to convert an address into geographic coordinates. Use when you need latitude and longitude from an address.
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
Geometry Operation
Tool to perform geometric operations on stored polygon geometries. Use when combining or intersecting multiple stored geometries.
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
IP Geolocation
Tool to determine geographic location of an IP address. Use when you need to lookup location information by IP.
Message Reaction Removed
Triggered when a reaction is removed from a message in Slack. Supports optional filtering by channel and emoji name.
Generate isoline (isochrone/isodistance)
Tool to generate isochrone or isodistance isolines. Use when visualizing reachable areas from a point; use `id` to poll ongoing calculations.
Reaction Added Trigger
DEPRECATED: use `SLACK_MESSAGE_REACTION_ADDED` instead. Triggered when a reaction is added to a message in Slack.
Map Matching
Tool to snap GPS traces to the road network and correct inaccuracies. Use when raw GPS points need alignment to roads.
