Seven Parameter Transformation

⚙️

7-Parameter Transformation

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.

Translation Parameters:
dx (X-axis), dy (Y-axis), dz (Z-axis) in meters
Rotation Parameters:
rx, ry, rz in radians
Scale Parameter:
s in parts per million (ppm)
Example:
dx: -679.0m, dy: 669.0m, dz: -48.0m, rx: -0.00000376632, ry: -0.00000094672, rz: -0.00000285841, s: 0.0000000000

3Latitude and Longitude Formats

📐

DMS Format (Degrees, Minutes, Seconds)

DMS format represents geographic coordinates using degrees, minutes, and seconds for precise location specification.

Example:
Latitude: 40°26'46''N
Longitude: 79°58'56''W

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 Degrees Format

Decimal format uses a single decimal number to represent coordinates, making it ideal for computational applications.

Example:
Latitude: 40.446
Longitude: -79.982

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.
