I really can't get what's happening.

I want to add a placemark whose coordinates I know. Therefore, I go to ADD, PLACEMARK, then ADVANCED, LOCATION, and then I start to introduce the coordinates. Before I start introducing coordinates, there is already a coordinate in the place I am going to introduce my numbers (for example 32 19' 40.13 N). So I have to delete and start introducing my lattitude (for example 35 13' 32 N). When I finish latitude and place the cursor in the longitude box, it happens that what I have just finished typing , disappears, and is replaced by the original number (32 19' 40.13 N). Therefore, I am unable to insert my own coordinates, since it always changes to the coordinates that were there (I do not know where do they came from).

I understand that i am possibly missing something. Does someone help me and tell me what is it?

Many thanks

quinta, I am not sure from your explanation, but I think you need to change the order a bit. First click "Fly to" then insert the coordinates, and press enter. After you get to your place, then make a new placemark. Let us know if that does not work. It might be useful to read the help instructions about placemarks again just for a review.

And welcome to the Earth Community!

If you input incorrect values, GE will discard your input and replace it with the former values.

I think you can do it your way, but maybe the characters you used for the degree and minutes were not recognized by the program as valid.
Try leaving out the degree, minute and seconds characters and just type
32 19 0.13 N
It should work that way, at least it works for me.

And dont't forget to edit the "lookat" coordinates as well!

The faster way though is the one described by periboob in the previous post, as you have to input the coordinates just once: If you fly to the coordinates, they are inserted into the location and the lookat fields.

PS: The format required for the coodinates is defined by Tool/Options/View.

Xav,

GPS portable aviation receivers like the GARMIN GPSMAP 296 use the location format hddd mm.mmm and most aviation locations in printed publications (Jeppesen etc.) are given in the even shorter format hddd mm.m.

I wonder, whether you by chance could point me to a source for an easy conversion formula of the above aviation formats into the rather tedious Lat/Long/Sec format EarthGoogle uses?
Better of course would be if EarthGoogle would offer its users to choose between different location formats at the input form.

Thanks

Hi,

you can use the formats you described, just put a blank between the degrees and minutes part.

GE's user interface accepts quite a few formats for input.

As far as I have found out, the basic rules are:

If you input just one number , it is regarded as degrees
Two numbers (separated by a space) are degrees and minutes
Three numbers (separated by spaces) are degrees, minutes and seconds
Only the last number may have a fractional part.
Leading zeroes are ignored.
You can put the letters designating the hemishere (N/S/E/W or n/s/e/w) to the front or to the end of the numbers.
If you do not use letters for the hemispheres, positive values are north and east, negative ones are south and west.

Some examples which are equivalent:
-40.75833333
W 040 45.5
40 45 30w
-40 45.50
w40 45 30.00

In the "Fly To" input box latitude comes first if you do not use the letters (nsew), with the letters, order doesn't matter.
If you are using the letters, the letters separate latitude and longitude.
Without the letters the numbers are evaluated in a way that gives a pair of coordinates:
Up to 4 numbers: The last number is longitude, the first (1,2 or 3) numbers are Latitude.
5 numbers: thee last 2 numbers are longitude (deg and min)
6 numbers: the last 3 numbers are longitude (deg, min and sec)
If you want it to get parsed diferently, put a comma between latitude and longitude numbers or use the letters.
Another way to separate lat an long is to use the appropriate signs for deg () min (') and sec (") so that GE can figure out, where the latitude ends and the longitude starts, ie 10 20 30 40' evaluates to a latitude of 10 degrees 20 minutes (North) and 30 degrees 40 minutes east.


This applies only to the user interface.
In KML code you have to use decimal degrees (ie. -40.75833333). You can convert from degrees/minutes/seconds with this formula:
degreesdecimal = degrees + minutes/60 + seconds/3600
Or you can make GE do the conversion for you:
Go to Tools/Options..., select the ""View"-tab, in "Rendering" selcect "Degrees". Click OK.
Add new Placemark., select "Advanced". In the "location" or "View" tab enter your coordinates into the Latitude or Longitude field ia valid format you like. Press tab to leave the field and GE converts your input to the format you selected in Tools/Options.

hope this helps

Hi,

Thank you so much for your very helpful advise! It works well and I could enter my waypoints as advertised.

However when I tried to transfer waypoint files from my GARMIN GPSMAP 296 (portable aviation GPS receiver) into GoogleEarth Plus, the program refused to work and myself as a clueless user ended up with some mystic programmer instructions. But that is another story.

Cheers,
EOBC

I don't know the details about GPS data files but there are several post about this subjetct on the BBS. Try searching the Board for "GPS" or "garmin"
