Write a filter for a dataset of GPS locations

$30-250 USD

Paid on delivery
Some of the GPS trackers (namely the TR06 and GT06E models by Concox) we use have a firmware bug which causes very strange positions to be sent to our server. Essentially the GPS hardware will sometimes transmit the same device timestamp with 2 different coordinates, sometimes make the vehicle jump backwards, even tho the vehicle is traveling on a road and going forward. Unfortunately, we are not able to fix the firmware of the device so we will have to develop a filter script in php which scans our db for these specific devices and then reads through the locations and based on a filter logic determines the error records and deletes them. Please only bid for this project if you have previous experience with GPS data processing. Suitable bidders will be issued database access for a demo set of data as it comes in from the hardware.

Hello, I had similar issues in the past and I decided to filter this data at the database level. I have done it in MSSQL and PostgreSQL databases; it won't be a problem for me to work with MySQL. What I did was to calculate the speed, distance, and period of time, based in previous positions of the device, then create a small function that decides if the new position is acceptable or not. For logging purposes, the deleted data should go to another table. I'm not so proficient in PHP so my solution would be 100% applied to the database level, let me know if it works for you. Thanks.
