GPS Coordinate Formats - INI

GPS coordinate formats are methods for numerically representing positions on Earth using latitude and longitude. The main formats include Decimal Degrees (DD), Degrees Minutes Seconds (DMS), and Degrees Decimal Minutes (DDM), each used according to specific applications. Additionally, projected coordinate systems such as UTM (Universal Transverse Mercator) and MGRS (Military Grid Reference System) exist. Accurate conversion between these formats is crucial for surveying, aviation, marine navigation, and mapping applications.
