Getting bounding box by passing specific parameters?

Hi,

You have already defined the function you need. Supposed the resolution is in meters, my suggestion would be:

1. Convert your point from geographic coordinate system (WGS84) to projected coordinate system (e.g., UTM). See the difference here.
2. Based on the dimension and the resolution, you can calculate the coordinate of the lower left and upper right points which form the bounding box.
3. Convert the CRS back to WGS84 (optional). If you want to make requests in WGS84, the resolution will also be in degree. Although you may find some approximate conversion from between degree and meter, the error will be larger as the latitude increases. To have the resolution (in meters) and dimension as close as calculated, you may want to stick with projected coordinate system.

Best Regards

Thanks a lot, your answer was really helpful
