Mapping content delivery
Aspects of the present disclosure relate to mapping content delivery. A client device provides, to a map management server, a request for a map of a geographic region. The client device receives, from the map management server, an identification of tiles for the map. The client device provides, to a first tile server, a request for the tiles for the map. In response to receiving the tiles from the first tile server: the client device displays the map of the geographic region based on the tiles.
1. A method implemented at a client device, the method comprising:
providing, to a management server and from the client device, a request for data;
receiving, from the management server in response to the request for the data, an identification of tiles associated with the data;
providing, to a first tile server and from the client device, a request for the tiles;
in response to failing to receive the tiles from the first tile server within a threshold time period from the request for the tiles:
causing the client device to transmit a plurality of requests for the tiles, each request from the plurality of requests being directed to one of a plurality of tile servers, each request from the plurality of requests identifying the tiles that have been previously identified by the management server;
receiving the tiles from a second tile server from among the plurality of tile servers; and
providing for display, at the client device, of a visual representation of the data using the tiles.
2. The method of claim 1 , wherein the data comprises a map of a geographic region.
3. The method of claim 2 , wherein each tile from among the tiles tile stores a portion of the map at a given zoom level as an image taking up a predefined area measured in pixels.
4. The method of claim 1 , wherein failing to receive the tiles from the first tile server comprises receiving a failure message from the first tile server.
5. The method of claim 1 , further comprising:
selecting the first tile server from a set of tile servers based on a geographic distance between the client device and the first tile server being less than a geographic distance between the client device and each other tile server from among the set of tile servers.
6. The method of claim 5 , wherein the set of tile servers comprises the first tile server and the plurality of tile servers.
7. A non-transitory machine-readable medium storing instructions which, when executed by a client device, cause the client device to perform operations comprising:
providing, to a management server and from the client device, a request for data;
receiving, from the management server in response to the request for the data, an identification of tiles associated with the data;
providing, to a first tile server and from the client device, a request for the tiles;
in response to failing to receive the tiles from the first tile server within a threshold time period from the request for the tiles:
causing the client device to transmit a plurality of requests for the tiles, each request from the plurality of requests being directed to one of a plurality of tile servers, each request from the plurality of requests identifying the tiles that have been previously identified by the management server;
receiving the tiles from a second tile server from among the plurality of tile servers; and
providing for display, at the client device, of a visual representation of the data using the tiles.
8. The machine-readable medium of claim 7 , wherein the data comprises a map of a geographic region.
9. The machine-readable medium of claim 8 , wherein each tile from among the tiles tile stores a portion of the map at a given zoom level as an image taking up a predefined area measured in pixels.
10. The machine-readable medium of claim 7 , wherein failing to receive the tiles from the first tile server comprises receiving a failure message from the first tile server.
11. The machine-readable medium of claim 7 , the operations further comprising:
selecting the first tile server from a set of tile servers based on a geographic distance between the client device and the first tile server being less than a geographic distance between the client device and each other tile server from among the set of tile servers.
12. The machine-readable medium of claim 11 , wherein the set of tile servers comprises the first tile server and the plurality of tile servers.
13. A system comprising:
processing circuitry of a client device; and
a memory storing instructions which, when executed by the processing circuitry, cause the processing circuitry to perform operations comprising:
providing, to a management server and from the client device, a request for data;
receiving, from the management server in response to the request for the data, an identification of tiles associated with the data;
providing, to a first tile server and from the client device, a request for the tiles;
in response to failing to receive the tiles from the first tile server within a threshold time period from the request for the tiles:
causing the client device to transmit a plurality of requests for the tiles, each request from the plurality of requests being directed to one of a plurality of tile servers, each request from the plurality of requests identifying the tiles that have been previously identified by the management server;
receiving the tiles from a second tile server from among the plurality of tile servers; and
providing for display, at the client device, of a visual representation of the data using the tiles.
14. The system of claim 13 , wherein the data comprises a map of a geographic region.
15. The system of claim 14 , wherein each tile from among the tiles tile stores a portion of the map at a given zoom level as an image taking up a predefined area measured in pixels.
16. The system of claim 13 , wherein failing to receive the tiles from the first tile server comprises receiving a failure message from the first tile server.
17. The system of claim 13 , the operations further comprising:
selecting the first tile server from a set of tile servers based on a geographic distance between the client device and the first tile server being less than a geographic distance between the client device and each other tile server from among the set of tile servers.
