Transform coordinates between 18+ geodetic systems with professional-grade accuracy
The seven-parameter transformation is a rigorous mathematical model for converting coordinates between different geodetic datums with millimeter-level accuracy. This method accounts for translation, rotation, and scale differences between coordinate systems.
Learn about different coordinate formats and their applications
DMS format represents geographic coordinates using degrees, minutes, and seconds for precise location specification.
DMS format divides each degree into 60 minutes and each minute into 60 seconds. Direction indicators (N/S for latitude, E/W for longitude) specify hemisphere.
Ideal for surveying, navigation, and applications requiring high precision.
Decimal format uses a single decimal number to represent coordinates, making it ideal for computational applications.
Decimal degrees combine the degree value with fractional degrees expressed as a decimal. Negative values indicate Southern or Western hemispheres.
Preferred format for GIS software, mapping applications, and web services.
