5. If you are given shorthand data like: 345.6, 654,3 (in Loran) that means that the fisherman knew

that the leading two digits were easily guessed. Think of dates in years. If I give you the year of

my kid's birth and say '05, then you know it is 2005. If I said '87, you will be sure that I am

wrong. So, you need to know the usual range of the first and second number digits. Off Sebastian

Inlet, FL, the loran numbers will be like 43600.0, 61926.0 or the GPS numbers will be 28 12.345

and 80 12.345. It is unlikely that I would ever see other than 43 for the first two digits of the TD1

and either 61 or 62 for the TD2.

6. Once you have a list, check to see that there are no commas in the list as you will be exporting it to

a CSV text format and an extra comma would miss align the data for that waypoint. Use

Edit>replace to replace commas with something else like periods. I often see data from

customers where a few of the loran or lat/lon numbers have commas instead of periods. Save the

file to the C:\LoranGPS folder for ease of finding it and save it as CSV or comma separated.

7. Once you have the CSV formatted file, use SeaMarks>Tools>Import Waypoints>text, comma

delimited. Then you have to find the file and set up the import as in the dialog shown below. The

first line of the file is displayed so that you can refer to it for deciding what fields go in what

order. When you have identified all the fields in the file, import it. You will be asked to identify

the chain number of the loran data. You should now see the data on the screen, possibly with GPS

numbers. If some or all GPS numbers are 0.0, then check File>File Properties to make sure the

center latitude and longitude are appropriate for the data being imported. If so, then fix them and

use Tools>Recalculate LL to fill in the GPS data.

8. Save the file, giving it a new name if desired.
