Hi there!

Can someone tell me how to display lat and long on webservcie in deg min sec format.
For example:
I have in my table lat and long written in DEG format as a POINT in PostgreSQL.
45.603333 represent 45deg36min12sec
So, my POINT which represent some citiy is
(45.60333,16.771666)
How to display on webservice this point in this format:
45º36'12" 16º46'18"

Thanks for help!

Hi Molin

It is simple mathematics. Multiply with 60 to get the minutes, mulitply the remainder again with 60 to get the seconds.

Hi Marc,

my problem is not how to get deg min sec, but how to get symbols behind degrees (º), minutes (') and seconds ('') on the web.
I have in my table coordinates in DEG format (51.508333, 0.125277).This are the coordinates for London in table. Now, if I want to get coordinates of London in format degrees (º), minutes (') and seconds ('') on the web, what would my query have to look like.

For example, if I write:
select coordinates from cities where city='London';

I'll get this result
51.508333, 0.125277

and I would like to get something like this:
51° 30' 30'' 0° 7' 31''


Thank you for your time and help!

Molin

As I said in my previous post. You have to do the calculation yourself. I don't know of any inbuilt database function to do this. If you don't want to do this on the application level you can write a stored procedure to do this for you on the database level.
