The API makes it possible to query for features within a radius, do point in polygon queries, query for features in multiple composite layers, and augment data from the Mapbox Geocoding API with custom data. Put the cells into a priority queue sorted by the maximum potential distance from a point inside a cell, defined as a sum of the distance from the center and the cell radius (equal to cell Simplifying your data means removing complexity in the vertices of your geometry. The Mapbox Tilequery API allows you to retrieve data about specific features from a vector tileset, based on a given latitude and longitude. maps. This guide covers how to use Mapbox Boundaries with the Mapbox Tilequery API to query points in polygons. A newer version of the SDK is available. coordinates; In the original post, linked above, this line was written as coords = data.

See the code, the data, and the result of this example. Point vertices use the same point filter, and render these points twice: once as a larger-radius halo, and again as the vertex inset point. This example code is part of the Maps SDK for Android Examples App, a working Android project available on GitHub. To specify a constraint specific to Polygons, it is useful to introduce the concept of a linear ring: A linear ring is a closed LineString with four or more coordinates. Here is an example that demonstrates how a user can aggregate point data into polygon hierarchies (using the data join technique and the Tile Query API) to analyze hospital charges in the US - all rendered through an interactive map with GL JS. 1, in the Maps SDK documentation.
