[sumo-user] Inquiry : Conversion from co-ordinate axis to Latitude and L

[Sheshadri Kalkunte Ramachandra <sheshadrik@xxxxxxxxxx>]

Namaste,

I used the following api to convert from co-ordinate axis to geo co-ordinates.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Code:

position = traci.vehicle.getPosition(self.vehicleId)

pos_x = position[0] # cartesian X
pos_y = position[1] # cartesian Y

geo_co_ord = traci.simulation.convertGeo(pos_x, pos_y, fromGeo=False)

The geo co-ordinates which i receive are incorrect. I have checked by putting them in google maps.

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Outputs:

The cartesian co-ordinate  (50450.7527098387, 22602.868908196364)  => returned by getPosition(vehicleId)

The geo co-ordinate  (777805.9327098387, 1439436.2689081964) => returned by convertGeo(pos_x, pos_y)

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

What is confirmed so far:

traci.simulation.convertGeo(pos_x, pos_y, fromGeo=False) is able to convert from cartesian to geo , and geo to cartesian correctly.

Have tested it with a valid geo co-ordinates.

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

What is not clear:

position = traci.vehicle.getPosition(self.vehicleId)

The position returned by the getPosition() seems to be incorrect, or we might be wrongly interpreting it. 

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Please let us know what might be wrong here.
