i tried make link to Google maps and place pin in position based on coordinates. Make this link is not problem. When I click on this link and check pin position, then I see not correct position.
I tried reached areal of "Brutal Assault festival" (for example - another places have same bug). Link to this place on Google maps - https://www.google.cz/maps/place/Festival+Brutal+Assault/@50.3404166,15.9333541,17z/data=!3m1!4b1!4m5!3m4!1s0x470e7de678b98f57:0x775f2cf0460db4c2!8m2!3d50.3404166!4d15.9355428
1st try:
https://www.google.com/maps/place/50.3404166,15.9333541
this link Google transformed to:
https://www.google.com/maps/place/50%C2%B020'25.5%22N+15%C2%B056'00.1%22E/@50.3404166,15.9311654,17z/data=!3m1!4b1!4m5!3m4!1s0x0:0x0!8m2!3d50.3404166!4d15.9333541
Here is problem my coordinates are "50.3404166,15.9333541", but in final Google link I see "50.3404166,15.9311654". But I don´t know why... 1st coordinate Google allowed, but 2nd changed... Why???
2nd try:
http://maps.google.com/maps?q=50.3404166,15.9333541
Same final link on Google, same result, same bad placed pin...
3nd try:
https://www.google.com/maps/search/?api=1&query=50.3404166,15.9333541
Same final link on Google, same result, same bad placed pin...
4th try:
I tried to round off coordinates, but nothing happend. When I rounded to only two decimal places then I get different place. But this is logical only "two decimal" is few.
