Abstract
Concepts for clustering geographic features for graphical representation of the geographic features on a geographical map are presented. One example comprises identifying a geographic feature having: a first attribute value; and a geographic location. For each of a plurality of different map zoom levels, a cluster value is generated based on the map zoom level and at least one of the first attribute value and geographic location of the geographic feature. The cluster value for a map zoom level defines a cluster that the geographic feature belongs to for the map zoom level. Cluster values generated for geographic features according to such an example may then be used to group the geographic features for a particular map zoom level.
Claims20
A computer-implemented method for clustering geographic features for graphical representation of the geographic features on a geographical map, wherein the method comprises:
- identifying a geographic feature having:
- a first attribute value;
- and a geographic location;
- generating, for each of a plurality of different map zoom levels, a cluster value based on the map zoom level and at least one of the first attribute value and geographic location of the geographic feature, wherein the cluster value for a map zoom level is adapted to define a cluster the geographic feature belongs to for the map zoom level;
- and
- associating the generated cluster values for each of the plurality of different map zoom levels with the geographic feature.
A computer program product for clustering geographic features for graphical representation of the geographic features on a geographical map, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processing unit to cause the processing unit to perform a method comprising:
- identifying a geographic feature having:
- a first attribute value;
- and a geographic location;
- generating, for each of a plurality of different map zoom levels, a cluster value based on the map zoom level and at least one of the first attribute value and geographic location of the geographic feature, wherein the cluster value for a map zoom level is adapted to define a cluster the geographic feature belongs to for the map zoom level;
- and
- associating the generated cluster values for each of the plurality of different map zoom levels with the geographic feature.
A system for clustering geographic features for graphical representation of the geographic features on a geographical map, wherein the system comprises:
- an identification component configured to identify a geographic feature having:
- a first attribute value;
- and a geographic location;
- a calculation component configured to generate, for each of a plurality of different map zoom levels, a cluster value based on the map zoom level and at least one of the first attribute value and geographic location of the geographic feature, wherein the cluster value for a map zoom level is adapted to define a cluster the geographic feature belongs to for the map zoom level;
- and
- a data management component configured to associate the generated cluster values for each of the plurality of different map zoom levels with the geographic feature.
