I have carefully calculated my PWS location using google maps, ACME mapper and other tools and get identical results. I enter the lat/long in meteobridge which supplies it to my CWOP account. The issue is the findu map data that CWOP shows is about 140 ft. from the actual location. Any ideas where I am going wrong? Is this "good enough?" because it is just weird...

CWOP station: http://www.findu.com/cgi-bin/find.cgi?call=EW9200

First pic is findu location (incorrect)
Second pic is actual location in ACME mapper with lat/long displayed at bottom (correct)
Third pic is my entry of lat long in meteobridge (correct)

Any ideas?

CWOP wants decimal degrees not decimal, minutes, seconds like some default map locators. On Google earth options  change to decimal degrees or use   http://mapper.acme.com/    change to satellite for exact location.

thanks but if you look at the pictures it looks like in acme mapper i am using decimal degrees, i am using satellite image to get the exact spot, and i entered the value in meteobridge as decimal degrees. thanks, any other ideas or am i missing something?

Odd I was going to look on Gladstone and you're not there. http://weather.gladstonefamily.net/site/E9200

I am brand new. Findu has me but I just sent the email request to CWOP to be switched to "active." Then once that occurs I understand it takes 5-7 days to appear on Gladstone... I see Gladstone has a way to slightly move your location but I don't know if that officially changes your location in the eyes of CWOP.

140' isn't too bad, if you can get within 50' you're lucky.

I discovered a bug in the way the Meteobridge converts Decimal Degrees to the format that CWOP requires (LORAN). I've reported it to Boris and he let me examine that part of the code and I found the error.  He has confirmed. Next update should fix this.
