Hi there Alex..

I am using LNM v3.0.6 and have a slight problem that has not been experienced before.

When I create user created waypoints or create an "on map" range ring the intended coordinates care some 69 nm off to the east.

IE: I try to create a user point at location 52 20.75, 0 56.58  >>  this results in a user point created but at location 52 20.80, 0 56.60 which is 69 miles to the east. 

Same thing occurs when trying to add a range ring at a location.. it is created but 60-59 miles to the east. No matter what the display map format is being used. (IE: Google Satellite map).   (And No external navdata being used)

I have a fresh scenery library database build. (I run the LNM map external to the Flight tables as pictured below and the monitor is a secondary 3440x1440 monitor (144 mhz).(native resolution). But no matter which monitor is being used to display LNM, ( I run 4 monitors all at native resolution), the location of the userpoint or range ring that is being created displays on the lnm map but far away from the intended location.

I have also turned off all add-ons to determine if any are interfering with the LNM process of plotting the userpoints and range rings at the intended location but makes no difference... This abnormality makes no sense- perhaps my little_navmap_userdata.sqlite is corrupt?

Any suggestions would be appreciated to rectify this issue.

Thanks in advance

Norm

 

PS: Even trying to edit an existing waypoint or user created in any way moves/change the late/long of the waypoint- so it would appear that lat/long is stuck

What is 52 20.75, 0 56.58? Degree and decimal minutes? I think you miss the N/S/E/W designators or a sign.

You have to enter N52 20.75, W0 56.58 or 52 20.75, -0 56.58 (Google format) which results in 52° 0' 0,00" N 0° 56' 34,80" W. Otherwise LNM puts you on the wrong side of the Meridian. See here for details: https://www.littlenavmap.org/manuals/littlenavmap/release/latest/en/COORDINATES.html

Inadvertently I had my Units - Coordinates set in LNM Tools to Degree, Decimal Minutes for Google.

I will revert to Lat/long (with sign) ir Just Degree, Decimal Minutes, and see if that will correct Lat/Long when I create userpoints..

(This just started doing this... (Will read the manual item (71.) to make sure all is correctly set up. Thanks Alex

LNM can digest all kind of coordinate formats independent of the output format.
The decimal degree output settings in options are the only ones which can affect reading (lat/lon vs. lon/lat).

I cannot rule out the possibility of errors when reading coordinates in LNM but I just checked with Google coordinates and the point does not move. Means LNM can read its own format.

Well, it seems that the units setting in LNM: Degree, Decimal Minutes for Google.  was causing the issue. I changed the units to  LNM Coordinates to: Degree, Minutes, Seconds then shut down and restarted, and this has fixed the issue. Adding range rings and/or creation of userpoints are working again, as intended: they are being applied and showing on the on the map where created.

Not sure why the Units in LNM: Coordinates if set to  Degree, Decimal Minutes for Google was changing the lat/long locations but the rest of the units have not issued plotting the correct the lat/longs.

Thanks Alex.

Hi Norm,

good catch.👍

LNM misses the sign in the coordinate output if you click west of the Meridian line but only if you're close to it. 
Will fix for 3.0.7.

Yes I was in the UK - Gloucestershire EGBJ, Sywell EGBK, Old Warden EGTH. Glad that this helped figure it out.  LNM is the best flight planning/In-flight app out there. Excellent job.

Thanks again Alex and appreciate all your work.

Best Regards

Norm
