More FORMAT_GEO_MAP/OUT format options

[KristofKoch]

Description of the desired feature

Currently the formatting options for geographic coordinates offers quite a few options but might benefit from some more.

Allow F and G in front of string

Currently the WESN sign is only allowed after the numbers. I could make good use of them in front of the numbers as well.

Current behaviour:

ddd:mm:ss[F|G] -> 52°37'19"N or 52°37'19" N

Proposed addition:

[F|G]ddd:mm:ss -> N52°37'19" or N 52°37'19"

The proposed leading F option is common in aviation context.

Leading/trailing Zeroes

In aviation usually all places of a coordinate are written even if they are zero. This is done to make sure not digit is accidentally missing. To my knowledge currently single digit degree latitude and single or double digit degree longitude can only be written as 1°N, 3°E, 47°W and not as 01°N, 003°E, 047°W. Similar with arc minutes and seconds. They are only plotted if not zero.

Current behaviour (three degrees north latitude, nine degrees west longitude):

ddd:mm:ssF -> 3°N, 9°W

Proposed addition:

DDD:MM:SSF -> 03°00'00"N, 009°00'00"W

While you might have even better ideas how to implement this I found capitalising the letters quite nice as it maintains backwards compatibility

Both proposals together

FDDD:MM:SS -> W009°00'00"

These are good suggestions, @KristofKoch. Once EGU is over etc I will have a look if your syntax is the best option or not, but I agree with the functionality. 6.3 though.

PS! #3562

[KristofKoch]

I found myself needing the W009°00'00" output format again and was about to write a feature request – turns out I wrote one already.

Is this still considered a useful addition?

[PaulWessel]

Obviously this got lost in the shuffle when there are too many issues pending. I will refresh my memory of how this could be done.

[KristofKoch]

Good morning Paul, thank you for looking into this again. No worries, it is nothing a visit to a vector graphics program can't fix. It is just tedious work doing it manually.
