Convert location coordinates to map tile indices
For a mapping workflow that needs precise tile references, calculate the right Web Mercator indices from the location context.
Trigger
View Created
Triggers when a new Notion view is created. Fires workspace-wide. The payload includes `data.view_type` (`table`, `board`, `gallery`, `calendar`, `list`, `timeline`, `gantt`) and `data.parent` pointing at the view's tree parent (typically the teamspace), so customers can filter downstream.
Action
Coordinates to Tile Indices
Tool to convert geographic coordinates to Web Mercator XYZ tile indices. Use when mapping a lat/lng to its containing tile at a given zoom level.
Why this helps
Tile math is a small technical detail that can stop location work and pull attention away from the actual decision.
- Avoid manual tile-index calculations.
- Create a consistent coordinate reference for map work.
- Reduce friction in technical location workflows.
Setup
Build it in a few focused steps.
- 1Connect Notion and Here to Notis once in the portal.
- 2Create an automation in the portal or ask Notis conversationally.
- 3Describe in one prompt that a new location view should calculate tile indices from its coordinates and zoom context.
- 4Select Notion View Created and choose a report channel.
- 5Test with one view and known coordinates and zoom.
Questions about this workflow
What are tile indices used for?
They identify the Web Mercator map tile containing a latitude and longitude at a chosen zoom level.
Is this useful for everyday trip planning?
It is mainly useful when a mapping workflow needs tile references for subsequent map imagery or overlays.

Supported Triggers and Actions
Notis builds workflows that link Notion to Here. A trigger fires from one place; an action lands in another.
Notion triggers
Here actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Autosuggest Places
Tool to fetch possible completions for a partial search term. Use after capturing a partial query and location context to generate typeahead suggestions.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Browse Places
Tool to search for places around a given location with optional filters. Use when you need nearby points of interest filtered by categories, food types, or name.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Calculate Fleet Telematics Route
Tool to calculate a route between waypoints with vehicle profile options. Use when planning a route with toll and vehicle constraints.
Comment Created
Triggers when a new comment is created in Notion. Optional `page_id` filter scopes to comments on a specific page. When omitted, fires for any new comment in the workspace the integration has access to. Requires the 'Read comments' capability on the Notion integration. If a connection was authorized before that capability was enabled, the user must re-authorize the connection for comment events to flow.
Coordinates to Tile Indices
Tool to convert geographic coordinates to Web Mercator XYZ tile indices. Use when mapping a lat/lng to its containing tile at a given zoom level.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
Discover Places
Tool to discover places and addresses by free-form text near a location. Use when you need to find points of interest or specific addresses from a natural-language query.
Database Created
Triggers when a new Notion database (the container) is created. A database is the post-2025-09-03 container that holds one or more data sources. This trigger fires for the container's creation event (`database.created`), distinct from `NOTION_DATASOURCE_CREATED` which fires when a new data source is added to an existing database. Most customers calling Notion's `POST /v1/databases` (the legacy API) or creating a database via the Notion UI will see this event. Adding a new data source to an existing database fires `data_source.created` instead — use `NOTION_DATASOURCE_CREATED` for that. Notion's payload puts `entity.type: "block"` (the container is a `child_database` block in the content tree) and `entity.id` is the database id.
Geocode Address
Tool to convert structured address data into geographic coordinates. Use when you need precise lat/lng from a free-text or qualified address input.
Data Source Created
Triggers when a new Notion data source is created. Fires workspace-wide. The payload's `data.parent` carries the data source's tree parent (typically the teamspace) for downstream filtering. A single template-based database creation can fire multiple `data_source.created` events at once — one per data source the template instantiates.
Get Aerial Tile
Tool to retrieve a satellite/aerial map tile. Use when you need tile imagery for a given zoom level and coordinates.
Data Source Schema Updated
Triggers when a Notion data source's schema is updated. Fires on column add / remove / rename. Payload includes `data.updated_properties: [{id, name, action}]` so consumers can discriminate the kind of change downstream. Optional `data_source_id` filter scopes to schema changes on a single data source. When omitted, fires for any schema change in the workspace the integration has access to. Note: adding a column also fires `page.properties_updated` once per existing row in the data source. Customers wanting a single structural-change signal should use this trigger.
Get Base Map Tile
Tool to retrieve a base map tile image without labels. Use after determining tile scheme, zoom level, x/y coordinates, size, and format.
