If you're not able to incorporate a third-party rendering product into your
solution, then you might have to create your own 3D Tiles renderer. This
approach requires that you consider the following important factors:
When serving Photorealistic 3D Tiles, the Map Tiles API returns URIs for
children tilesets. These tileset URIs are not regular URLs. They include only
the path and parameters component. They don't contain your API key, which is
required to authorize your request. For more information, see the
3D Tiles Specification.
Requests and responses
Here are some examples of Photorealistic 3D Tiles requests and responses. You
inspect them by using the Chrome Developer Tools.
You should attach any parameters that appear in the tileset URI, together with
your API key, when you construct the subsequent tile requests. The 3D Tiles API
provides the following two parameters:
session
A built-in identifier for a 3D loading session. It's automatically generated
by the API. It must be attached by the renderer when constructing the subsequent
tile requests.
key
The API key that you used to access 3D Tiles service. You must attach it to
all subsequent tile requests.
Display attributions
Attribution means acknowledging the source of map tiles and is a requirement for
use of this API - this includes the Google brand attribution (logo) as well as
data attribution. The Google logo is available to you on the
Map Tiles API Policies page. Data
attribution information is returned in every tile response. Look for it in the
glTF tile, under
asset, copyright.
{"asset":{"version":"2.0","generator":"draco_decoder","copyright":"Data SIO, NOAA, U.S. Navy, NGA, GEBCO;Landsat / Copernicus"}}
You must aggregate, sort, and display this information on a line of text,
usually at the bottom of the rendering. This entails the following steps:
Extract all of the copyright information from all of the tiles in view.
Separate multiple copyright sources with a semicolon.
Sort the information based on the number of occurrences.
Display the copyright sources on-screen, ordered from most occurrences to the
least, similar to the way
Google Earth
does it.
