Abstract

An approach is provided for customizing map presentations. A semantic mapping platform determines context information for rendering a map on a user device. The semantic mapping platform then classifies a plurality of objects available for display in the map based on a level of association of each of the objects with the context information. The semantic mapping platform also prioritizes rendering of the objects based on the classification and causes, at least in part, actions that result in the rendering of the objects in the map according to the prioritization.

Claims

1. A method comprising:

determining context information for rendering a map;

classifying a plurality of objects available for display in the map based on a level of importance of each of the objects with respect to the context information;

prioritizing rendering of the objects based on the classification; and

causing, at least in part, actions that result in the rendering of the objects in the map according to the prioritization.

2. A method of claim 1, wherein a section of the map corresponding to one or more of the objects associated with the highest prioritization is rendered first.

3. A method of claim 1, further comprising:

determining display information about a display area available on a user device;

determining detail capacity associated with a total amount of detail that can be presented in the display area; and

allocating the detail capacity among the objects to be rendered in the map according to the prioritization,

wherein the rendering is performed differentially according to the allocation.

4. A method of claim 3, wherein the differential rendering is performed using a vector rendering engine and includes one or more techniques of exaggeration, elimination, typication, outline simplication, or a combination thereof.

5. A method of claim 3, wherein the differential rendering pregenerates tiles of differing amounts of detail that can be iteratively displayed using a map tile renderer.

6. A method of claim 3, wherein the detail capacity is determined, at least in part, on a specified level of zoom for rendering the map, a size of the map, a style of the map, or a combination thereof.

7. A method of claim 3, wherein the map is partitioned into sections and the detail capacity is determined individually for each section.

8. A method of claim 1, wherein the level of association of each of the objects with the context is classified, at least in part, using semantic information.

9. An apparatus comprising:

at least one processor; and

at least one memory including computer program code,

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,

determine context information for rendering a map,

classify a plurality of objects available for display in the map based on a level of importance of each of the objects with respect the context information,

prioritize the rendering of the objects based on the classification, and

cause, at least in part, actions that result in the rendering of the objects in the map according to the prioritization.

10. An apparatus of claim 9, wherein a section of the map corresponding to one or more of the objects associated with the highest prioritization is rendered first.

11. An apparatus of claim 9, wherein the apparatus is further caused to:

determine display information about a display area available on a user device;

determine detail capacity associated with a total amount of detail that can be presented in the display area; and

allocate the detail capacity among the objects to be rendered in the map according to the prioritization,

wherein the rendering is performed differentially according to the allocation.

12. An apparatus of claim 11, wherein the differential rendering is performed using a vector rendering engine and includes one or more techniques of exaggeration, elimination, typication, outline simplication, or a combination thereof.

13. An apparatus of claim 11, wherein the differential rendering pregenerates tiles of differing amounts of detail that can be iteratively displayed using a map tile renderer.

14. An apparatus of claim 11, wherein the detail capacity is determined, at least in part, on a specified level of zoom for rendering the map, a size of the map, a style of the map, or a combination thereof.

15. An apparatus of claim 11, wherein the map is partitioned into sections and the detail capacity is determined individually for each section.

16. An apparatus of claim 11, wherein the level of association of each of the objects with the context is classified, at least in part, using semantic information.

17. An apparatus of claim 9, wherein the apparatus is a mobile phone further comprising:

user interface circuitry and user interface software configured to facilitate user control of at least some functions of the mobile phone through use of a display and configured to respond to user input; and

a display and display circuitry configured to display at least a portion of a user interface of the mobile phone, the display and display circuitry configured to facilitate user control of at least some functions of the mobile phone.

18. A computer-readable storage medium carrying one or more sequences of one or more instructions which, when executed by one or more processors, cause an apparatus to at least perform the following steps:

determining context information for rendering a map;

classifying a plurality of objects available for display in the map based on a level of importance of each of the objects with respect to the context information;

prioritizing rendering of the objects based on the classification; and

causing, at least in part, actions that result in the rendering of the objects in the map according to the prioritization.

19. A computer readable storage medium of claim 18, wherein a section of the map corresponding to one or more of the objects associated with the highest prioritization is rendered first.

20. A computer readable storage medium of claim 18, wherein the apparatus is caused to further perform:

determining display information about a display area available on the user device;

determining detail capacity associated with a total amount of detail that can be presented in the display area; and

allocating the detail capacity among the objects to be rendered in the map according to the prioritization,

wherein the rendering is performed differentially according to the allocation.
