plot a course with Latitude and Longitude

[stefano]

Hallo captains!

I have a little question, really coming from a newbee...

The question is:
I have received an order to pick up the crew of a ship, and the msg is giving me latitude and longitude... 58.14 N and 01.36 W...
How i can plot the course on the map?

Sorry for this strange question, but i have to do this before i can come back to the base.

Thanks for all the advices!

Hi,

Unfortunatelly, in the stock map in game doest feature latitudes and logitudes. Mods such as GW add an overlay map which is exactlly the one found in your SHIII dir/documentation/SH3_MAP.jpg

Looking at a map though, the location is some 50 km south of Shetland Islands (UK)

Cheers!

HI and thanks for the answer, i guessed something like this, on the map are missed the parallel and the meridian.....

How i can put the map in the game??

Thanks again!!
Cheers!

Hi Stefano,

You need to click on to the SH3 Community Wiki "sticky" at the top of the forum, then click on to "Navigation".

edit: failing that, you could make your own Lat/Long plotting sheets using 10ths of inch as Lat increments for nautical miles, then simply multiply the number of minutes of Longitude by the Cos of Lat to get the number of miles and plot at the desired scale. For example, to plot your position W20° 16.5' on N40°, at a scale of 10 tenths of an inch per 10 nm, multiply 16.5 x cos 40° = 16.5 x 0.766 = 12.6 tenths of an inch.

Cheers,

Hi don1reed!

If i have understand good, following your formula, i should have to go in a course of 3,2 degrees for around 10,12 NM if i have to reach, let say. a randevous on this latitude and longitude, right?
I hope.. i was not so good with these things in school...

Thanks for the advice!!

Cheers back!!

Here's something right up your interests, Stefano-:

http://www.offsoundings.info/navl.htm

about half way down the page there are free DL for plotting sheets and things necessary for navigation.

see posplot.zip

Have a great Sunday!

Here I've made a plotting sheet using the formula Longitude minutes x cos Latitude.

my base is 1 tenth of inch = 1 nm Latitude on right vertical (meridian). You could use mm or cm...whatever, I use tenths of inch 'cause it's easier for my old eyes to see.
All distance on natical charts is measured in minutes of LATITUDE

36' x cos 58° = 19.07 tenths of inch west of 001° Longitude.

This is how you would plot your position. Now, plot other ship's position. If the other ship is farther than 2 nautical miles away, you then need a larger plotting sheet or a chart. The Navigation-L site has those plotting sheets.

Thanks a lot!!
You have been very kind with this help!

I will study the site you have given me.

Thanks again !
Great sunday to you too !

Cheers!

I have the same doubt. So I searched the answer in internet. But it is seem that no mod can show latitude and longitude on NAV map directly.
So I try a stupid way: pause SH3 game, switch to Windows desptop, open the SH3MissionEditor, click File -> New, maximize the window, then zoom in the rough zone, move mouse cursor, now latitude and longitude of the cursor position will be shown in status bar.

@don1reed, Nice

The test messages you receive by radio with s.o.s. or s.s.s messages and such are not real in the game world. They just show up at certain times to enhance the experience of being in the world. But most of them have no ship associated with them in the 3d world. So trying to go there is pointless at best. However, it could be that some of those missions are about sightings of important warships/taskforces. Those are accurately scripted in the major mods, atleast in GWX.

The game map lacks true lattitude and longitude gridlines that you can see. It does however have moving black/white bars at the edges. Unfortunately with irregular zoom spacing relationship. But the rectangular coordinates of all landfeatures (like of sharp peninsulas) on the map (distance to Greenwhich Meridian and Equator) reflect the same spherical coordinates (true lattitude and longitude angles) you can find in i.e. Google Earth or Maps. Just measure the distance in kilometers horizontally and vertically in SH3 and divide by 120km per degree. No mod needed, just the line-tool wil do.
