Understanding GPS Coordinate Formats
Why Multiple Formats Exist?
Different GPS coordinate formats evolved to serve various navigation needs. Understanding these formats helps prevent confusion when sharing location information with other anglers.
Maritime tradition favors Degrees Decimal Minutes (DDM) because it balances precision with practicality. This format appears on most nautical charts and marine electronics.
Decimal Degrees simplify digital calculations but prove less intuitive for manual plotting. Scientists and programmers prefer this format for data analysis and mapping applications.
Converting Between Formats
Converting coordinates between formats requires simple mathematics or online tools. To convert DMS seconds to decimal minutes, divide seconds by 60.
For example, 30 seconds equals 0.5 decimal minutes (30 ÷ 60 = 0.5). This conversion proves useful when using older charts showing seconds.
Many GPS modules include built-in conversion functions. Access these through the settings menu to switch between formats without manual calculations.
