Hi,

I have a lot of panoramic images which are assigned to coordinates, do you have any suggestion/advise how can i calculate the arrow direction to enable to go the next panorama?

Thanks in advance!

Hi,

Thanks for answer! I have also tried some ways (postgis, bearing calculation) but i dont know how can i show this result as arrow in krpano (ath/atv or rotate)?

best regards

Hi spacerywirtualne,

Your plugin is not for download or? Anyway i need a solution to show my arrow direction in krpano automatically. Is there any way to draw a line between two lat/lon(maybe it is a solution)? Or bearing is really for me a solution?

Is there nobody who really worked with lat/lon?

Thanks in advance!

Hi Zephyr,

Thanks for answer! What do you exactly mean with (north being at 0)?

My Problem is;

if my way horizantal like this bearing from X to x2 => 90 and from X to x3 => 270. I see my arrow in left and right not in front of my car. (my arrow in the wrong place)

--------------------------------------------
x1 X x2
--------------------------------------------

if my way; X to X1 => 0 and X to X2 => 180. And my arrow in the right place, in front or back of my car.

| x1 |
| |
| X |
| |
| x2 |
| |

Do you have any advice? Thanks a lot!

Gülsün


My code calculating bearing in java
double dLon = Math.toRadians(Double.valueOf(point2.getLon())-Double.valueOf(point1.getLon()));

double y = Math.sin(dLon) * Math.cos(Double.valueOf(point2.getLat()));
double x = Math.cos(Double.valueOf(point1.getLat()))*Math.sin(Double.valueOf(point2.getLat())) -
Math.sin(Double.valueOf(point1.getLat()))*Math.cos(Double.valueOf(point2.getLat()))*Math.cos(Double.valueOf(dLon));
double brng = Math.atan2(y, x);
return (Math.toDegrees(brng));

Hi Zephyr,

Firstly thanks for answer but i cannot understand exactly, what do you mean?

I have to change my latitude and longitude for aliging to north 0? Because i tried your formula but it does not work for me. Or i have to calculate bearing of my lat/lon to north.

best regards

Thanks for answer :) i unterstand now :)
