Hi there

I Just implemented the SearchServer for your application.
Except for the HTML part in the labels (maybe return a Label2 without HTML)

I found that the Point coordinates are swapped.

An example call:

this return this (bbox are correct, just the coords of the points not):
swapped_coords.png

is this intended or is there a parameter to swap them?

Hello Dominik,

Yes, people with geodesy and cadastral survey background insist on that y/x order. I never remember the reason, but it's something related to the spheric trigonometry and geodetic conventions.

But since 1938 (I don't remember the exact date), civilians also use the infamous military coordinates, where the eastings values are always (450'000 to 900'000) bigger than the northings (50'000 to 350'000) values, so no confusion is posible. Prior to that, the origin was (unsurprisingly) Bern, with coordinates 0,0

In the LV95 system, x and y were replaced by northing and easting, but again no mixing is possible (within Switzerland though)

Regards,

Marc
