Can anybody please explain me how GetProjection() function works and what it is used for.?

@BoChang11 could you be more specific? Which file are you currently looking at?
@natashadsouza hd_map_common_test.cc, could you please explain what is the task of this function GetProjection().
I am trying to find the distance travelled by Autonomous vehicle over time. It would be great if you could help me with the useful function.
BR
@BoChang11 take a look at hdmap_common.h for additional details regarding the function.
Let me know if you have any additional questions. Thanks!
@natashadsouza Thanks for the reply. I will look into the program in hdmap_common.h and update you.
Could you please let me know is there a I can calculate/monitor the distance covered by autonomous vehicle during the course of the journey ?
BR
@natashadsouza Did you get chance to look at the query?
@BoChang11 sorry for the delay in responding. Currently there is no way to monitor the distance travelled by the car. It is a great suggestion though and something we would definitely consider as a feature request. Would you help me understand what you are trying to accomplish by calculating this?
@natashadsouza I want to keep track of the distance for every new route given, which will be used in making some of the decisions.
Thank you,
BR
I got the solution. We can get the distance covered by the ego vehicle in current lane segment by using GetProjection() as given below:
double adc_s = 0;
double adc_l = 0;
bool temp_ret = current_lane->GetProjection(car_point, &adc_s, &adc_l);
@BoChang11 that's great news. Do you mind making a pull request for others to also use it.
