Incorrect by ~100m google maps embed despite accurate lat/long

Question

I have an embedded google map, and am pulling the lat and long from a url saved in the db. However, the resulting map is always slightly off, usually by a few hundred meters. If I inspect the map, the lat/long are correct, but still the map is off.

Example, if I add this location: https://www.google.co.uk/maps/place/China+Town+Gate/@13.7381454,100.5116292,18z/data=!4m13!1m7!3m6!1s0x30e29921f76193f7:0x5864886b1bdc3702!2sYaowarat+Rd,+Krung+Thep+Maha+Nakhon,+Thailand!3b1!8m2!3d13.7413762!4d100.5080243!3m4!1s0x0:0xa90b006096d12511!8m2!3d13.7371669!4d100.513057

You can see the result here: http://prntscr.com/kx17rs Or live here: https://achefstour.com/tour/bangkok-food-tour

As you can see, the lat/long is correct, but the icon is way off.

If anyone can shed some light over why this could be happening, it would be much appreciated.

Answer 1

The coordinates in that URL 13.7381454,100.5116292 are the center of the map, not the location of the place. The Google Places Service returns 13.7371669, 100.513057 for the location of "China Town Gate"
