Abstract
The subject disclosure relates to ways to determine a data collection surveillance cadence. In some aspects, a process of the disclosed technology includes steps for receiving historic map data for one or more geographic regions, wherein each of the one or more geographic regions comprises one or more map features, calculating a change rate for each of the one or more map features, and determining a surveillance cadence for each of the one or more geographic regions based on the change rate for each of the one or more map features. Systems and machine-readable media are also provided.
Claims20
A computer-implemented method of maintaining a digital map, comprising:
- receiving historic map data for one or more geographic regions, wherein each of the one or more geographic regions comprises one or more map features;
- calculating, based on the historic map data, a change rate for each of the one or more map features, wherein the change rate is a rate of map updates for a map feature of the one or more map features over a duration of time;
- and
- determining a surveillance cadence for each of the one or more geographic regions, wherein the surveillance cadence is a data collection cadence based on the change rate for each of the one or more map features.
A system comprising:
- one or more processors;
- and
- a computer-readable medium comprising instructions stored therein, which when executed by the one or more processors, cause the one or more processors to perform operations comprising:
- receiving historic map data for one or more geographic regions, wherein each of the one or more geographic regions comprises one or more map features;
- calculating, based on the historic map data, a change rate for each of the one or more map features, wherein the change rate is a rate of map updates for a map feature of the one or more map features over a duration of time;
- and
- determining a surveillance cadence for each of the one or more geographic regions, wherein the surveillance cadence is a data collection cadence based on the change rate for each of the one or more map features.
A non-transitory computer-readable storage medium comprising instructions stored therein, which when executed by one or more processors, cause the one or more processors to perform operations comprising:
- receiving historic map data for one or more geographic regions, wherein each of the one or more geographic regions comprises one or more map features;
- calculating, based on the historic map data, a change rate for each of the one or more map features, wherein the change rate is a rate of map updates for a map feature of the one or more map features over a duration of time;
- and
- determining a surveillance cadence for each of the one or more geographic regions, wherein the surveillance cadence is a data collection cadence based on the change rate for each of the one or more map features.
