North American Overlay Mapping

To see a brief information page that discusses the type of information that the list-editor will accept, click 'Tools' > 'Edit Lists' to open the List Editor, then click on the down-arrow until you reach 'See the accepted data formats', and click on that item. This page expands on those descriptions.

I have tried to make the entry-requirements for a list quite easy to follow, or to generate by hand, or with a simple program. Looking at a typical line:
you can see that there are 4 items that go to make each entry, separated by commas. The order of the items must be maintained. The items are:

  • Manhatten - This is the location name, and has no function other than as an identifier. You can use any normal character, space, or underline, but not any other punctuation character. Its recommended that you keep the length of the name to 16 characters, as some of the display modes will truncate a name that is longer than that.
  • NY - This indicates the general area of the location. The program will check it for validity, then convert it to a three-letter code as appropriate. You could also enter the full state-name, in this case New York, or the name of a country, such as Mexico. All names are checked for validity, and spelling errors will be flagged.
  • 074.00W - This is the longitude of the location position, and is given here in decimal degrees. You could also use the older 'DegreesMinutesSeconds' format (example: 89d45m30s), and such entries will be converted into decimal degrees. Do not add extra decimal points (xx.123) or decimal values of seconds (xxdxxmxx.12s). The leading or trailing '0's are optional. The hemisphere containing the location position is indicated by a trailing 'W' for West, or 'E' for East.
  • 40.50N - This is the latitude of the location position, and is also given here in decimal degrees. The comments above also apply here, though in this case, the hemisphere containing the location position is indicated by a trailing 'N' for North, or 'S' for South.

Each entry in the list should be on its own line. There are no characters needed to show that the list has ended. Your list should be pasted into the 'Input List' box, completely replacing any characters that are already there.

You can also paste in a list that has been previously formatted by this program, for editing. Don't edit it first, just paste the complete list in to the 'Input List' box.

A full list of 3-letter state and country codes, and a tool to locate them, has been provided on the Check Codes page, but if you don't wish to look them up, enter the normal state/province/country name (i.e. Alabama) and if your spelling matches mine, the Country Code will be located and inserted.

The next job is to Validate the list. To find out how to do this, go to the Validate entries page.

Another way to understand the data layout that the Formatter will accept is to click the arrow one more time until you reach 'Show test data to experiment with'. This is explained in more detail on the Load test entries page.
