SeaMarks manual III USING THE PROGRAM •

10. Go through the various menus and try all the operations that you might use. Don't be shy, if you

mess up, nothing valuable is lost since the test file is all bogus data.

3. Building your own files

To start your own file, select FILE>NEW FILE. Each new file will inherit properties from the User Preferences, but

you can change them to suit the needs of this new file. Give the file a name and change the other properties as needed

and push OK. Next, use EDIT>ADD WAYPOINTS to put in waypoints. On this screen, you have the choice of putting

them in as Loran, as GPS, or both. Then just type in the data you want to put into each waypoint. They are saved to disk

as you enter them. The program will do its best to decipher your input and fit it to the desired information. If it has a

problem with an entry, it will show you the difficulty that it is having. If you are just trying to work outside the bounds

of your normal area, ignore the message, but if not, read it and try to see just what is wrong. .

You can enter Lat/Lon numbers in any one of four distinct forms. Use positive numbers for N and W and negative for S

and E. For example, the following are all equivalent and valid:

• 28.9873 degrees (DD.DDDD)

• 2859.238 or: 28 59.238 degrees, minutes (DDMM.MMM)

• 28 59 14.28 degrees, minutes, seconds (DD MM SS.SS)

You can use dashes in place of the spaces if you wish. If the program sees a number with two spaces it

will assume that it is the last type. A common mistake is to leave out the periods that are not

prominent on the GPS's display. Unfortunately, you cannot do that here. So, if you put in a number

like: 28 59 238, the program will complain that there are more than 60 seconds in the number as it will

think the 238 is seconds. It might, however, accept 28 59 001 as valid when it is not, so use the

accepted forms.

The most common form of GPS display is the third one (28 59.238). I like the second one since it is more compact.

You have choices for entering some other characteristics of the waypoint such as the name, color, the date code, depth,

Icon, and a symbol to represent the waypoint. Use the function keys F2 through F10 to type common words or phrases.

These can be programmed by you. You can also set the program to skip over fields you don’t use frequently with the Set

Field Preferences button.

4. Editing your files

The file, once created can be edited easily on screen in the spreadsheet. Just move the mouse cursor to the entry to be

edited and double click to place the cursor where you want it. You may have to delete or backspace over information

already there.

Some of the information is computed and cannot be edited unless you want to change the character of the waypoint. If,

for example, you want to correct the Latitude of a waypoint originally entered as Loran, then you must know the right

Latitude or you wouldn't be doing that. In that case, you go ahead and edit the Lat/Lon and that will turn the waypoint

into a calibration waypoint where both Loran and Lat/Lon are assumed correct as entered. No further calculations will

be performed on those waypoints except for figuring range and bearing. Range and Bearing cannot be edited as they are

based on the reference point. To change that, go to: Display> Set Range/Bearing Reference.
