Abstract

Multiple individually renderable map elements, each representing a respective physical entity in a geographic area, are rendered to generate a digital map of the geographic area. A description of an aggregate map feature that includes several but not all of the multiple map elements is received. The several map elements represent physical entities that form a common administrative unit. A selection of one of the several map elements is received via the user interface. In response to receiving the selection, the several map elements included in the aggregate map feature are automatically selected, and an indication that the aggregate map feature has been selected is provided on the user interface.

Claims

1. A method in a computing device for providing interactive map content via a user interface, the method comprising:

rendering a plurality of individually renderable map elements, each representing a respective physical entity in a geographic area, to generate a digital map of the geographic area;

receiving, by one or more processors, a description of an aggregate map feature that includes several but not all of the plurality of map elements, and wherein the several map elements represent physical entities with a preexisting logical relationship defining a common administrative unit;

receiving, by the one or more processors, a selection of any one of the several map elements via the user interface;

in response to receiving the selection, automatically selecting all of the several map elements included in the aggregate map feature, including providing an indication on the user interface that the aggregate map feature has been selected.

2. The method of claim 1, wherein providing the indication that the aggregate map feature has been selected includes providing an indication of a boundary of the aggregate map feature determined by respective geometries of the several map features.

3. The method of claim 2, wherein providing the indication that the aggregate map feature has been selected includes highlighting the several map features relative to other map features on the digital map.

4. The method of claim 1, further comprising:

receiving the plurality of individually renderable map elements from a map server, including receiving an identifier for each of the map elements, and

receiving an identifier of the aggregate map feature from the map server.

5. The method of claim 1, wherein the common administrative unit is an academic institution, and wherein the several map elements include map elements that represent buildings and map elements that represent pedestrian paths.

6. The method of claim 1, wherein the common administrative unit is a shopping mall, and wherein the several map elements include map elements that represent stores.

7. The method of claim 1, wherein the aggregate map feature spans multiple map tiles.

8. A non-transitory computer-readable medium storing thereon instructions for providing interactive map content via a user interface, wherein the instructions, when executed by one or more processors, cause the one or more processors to:

receive map data that describes a plurality of map elements, each representing a respective physical entity in a geographic area, wherein the map data separately specifies respective geometry of each of the plurality of map elements;

receive a description of an aggregate map feature that includes several but not all of the plurality of map elements, wherein the several map elements represent physical entities with a preexisting logical relationship defining a common administrative unit;

render the map to generate a digital map of the geographic area for display via the user interface; and

provide, via the user interface, a control for manipulating the several map elements of the aggregate map feature as a single map element.

9. The computer-readable medium of claim 8, wherein the user interface includes a touchscreen, and wherein the control is activated via a gesture applied to the touchscreen.

10. The computer-readable medium of claim 8, wherein the instructions further cause the one or more processors to highlight the several map features relative to other map features on the digital map in response to user activating the control.

11. The computer-readable medium of claim 10, wherein the instructions further cause the one or more processors to provide an indication of a boundary of the aggregate map feature determined by respective geometries of the several map features.

12. The computer-readable medium of claim 8, wherein the map includes respective identifiers for the plurality of map elements, and wherein the description of the aggregate map feature includes a separate identifier for the aggregate map feature.

13. The computer-readable medium of claim 8, wherein the common administrative unit is an academic institution, and wherein the several map elements include map elements that represent buildings and map elements that represent pedestrian paths.

14. The computer-readable medium of claim 8, wherein the aggregate map feature spans multiple map tiles.

15. A method in one or more computing devices for providing map data for generating interactive digital maps on client devices, the method comprising:

receiving, from a client device, a request for map data for generating an interactive digital map of a geographic area;

generating the map data including descriptions of geometries of a plurality of individually renderable map elements, each representing a respective physical entity in the geographic area;

generating a description of an aggregate map feature, wherein the aggregate map feature includes several but not all of the plurality of map elements, wherein the several map elements represent physical entities with a preexisting logical relationship defining a common administrative unit; and

transmitting the map data and the description of the aggregate map feature to the client device, wherein in response to a selection of any one of the several map elements via a client device user interface, the client device automatically selects all of the several map elements included in the aggregate map feature and provides an indication on the user interface that the aggregate map feature has been selected.

16. The method of claim 15, further comprising:

transmitting, to the client device, respective identifiers for the plurality of individually renderable map elements; and

providing, to the client device, an identifier of the aggregate map feature.

17. The method of claim 15, wherein the common administrative unit is an academic institution, and wherein the several map elements include map elements that represent buildings and map elements that represent pedestrian paths.

18. The method of claim 15, wherein the common administrative unit is a shopping mall, and wherein the several map elements include map elements that represent stores.

19. The method of claim 15, wherein generating the map data includes generating the descriptions of the geometries in a vector graphics format.

20. The method of claim 15, wherein each of the plurality of map elements is selected from a group including a road segment, a building, and a bounded area.
