Abstract

Example implementations described herein are directed to a system involving a cloud architecture and an edge architecture associated with one or more vehicles. The edge architecture can involve devices associated with the one or more vehicles and can conduct edge processing to determine, from Global Positioning Satellite (GPS) information, a proximity of the first apparatus to a first Geographic Information System (GIS) waypoint relative to a second GIS waypoint, generate index information representative of the proximity of the apparatus to the first GIS waypoint relative to the second GIS waypoint; and transmit the index information to the cloud architecture.

Claims

1. A system, comprising:

a first apparatus, comprising;

a first processor configured to;

determine, from Global Positioning Satellite (GPS) information, a proximity of the first apparatus to a first Geographic Information System (GIS) waypoint relative to a second GIS waypoint;

generate index information representative of the proximity of the apparatus to the first GIS waypoint relative to the second GIS waypoint; and

transmit the index information to a second apparatus.

2. The system of claim 1, further comprising a second apparatus comprising a second processor configured to:

for receipt of GPS information from the first apparatus, calculate a location of the first apparatus by determining the first GIS waypoint and the second GIS waypoint from the GPS information by a comparison of the GPS information to GPS information of one or more GIS waypoints;

for receipt of the index information, estimate GPS coordinates of the first apparatus from the index information.

3. The system of claim 1, wherein the index information comprises a first value that is set based on the proximity of the first apparatus to the first GIS waypoint compared to the second GIS waypoint, and, for the first apparatus being in proximity to an intersection, a second value indicative of another proximity of the first apparatus to a pathway of a plurality of pathways of the intersection.

4. The system of claim 1, wherein the first processor is configured to, for the proximity of the first apparatus to the first GIS waypoint compared to the second GIS waypoint not being determinable, transmit the GPS information to the second apparatus;

wherein for the first GIS waypoint not being valid for the GPS information, transmit the GPS information to the second apparatus;

wherein for the first GIS waypoint and the second GIS waypoint not being known, determine the first waypoint and the second GIS waypoint from the GPS information by a comparison of the GPS information to GPS information of one or more GIS waypoints.

5. The system of claim 4, wherein the first processor is further configured to transmit compression information indicative of uncompressed data when the first processor transmits the GPS information, and indicative of compressed data when the first processor transmits the index information.

6. The system of claim 2, wherein the second processor is configured to determine a GPS sampling rate that determines a distance between the first GIS waypoint from the second GIS waypoint for the first apparatus, and transmit the GPS sampling rate to the first apparatus;
