lat_to_y

When you use this transformation in a query it interprets the provided value as a latitude and maps it to a y position on the screen, given the provided zoom level.

For more information on using query functions and operators in a REST API request, see Queries. For an end-to-end description of how to create a query, see Creating a Query.

For an example of a query that uses this rule, see $pixel_within_tile.
