Re: Lat Long conversion for Tinytrak4


 

I know that, I'm asking about syntax.? Where do the NSEW or +- go in the list of numbers?

North is positive - South negative.
East is positive - West negative.

This is always easiest to explain with a fill example, so if you post information you want translated, we can use it as the example and provide the information in a way that you will be able to use in the future.

Search on DMS to DMM (Degrees Minutes Seconds to Degrees Minutes Minutes).
You will findsites like this:

To convert your lat/long from decimal degrees like DD.dddddd just use the 2 digits (for the first number, 3 for the second) before the decimal, then multiply the .dddddd by 60, and put that after the DD with 2 digits, decimal, then 4 digits after the decimal.? So 12.3456 degrees as latitude?becomes 1220.7360

To convert DD MM SS to DDMM.mmmm, use the 2 DD digits (3 for longitude), then 2 MM digits, then decimal/period, the divide SS by 60 (it should?be less than 1) and use the 4 digits after the decimal, padded with 0s if needed.? So 12 degrees 34 minutes 51 seconds as a longitude becomes 01234.8500

You always have 4 digits for latitude or 5 digits for longitude before the decimal, and 4 digits after the decimal, then the direction letter.
