pandas.DataFrame.xyz.ds_from_xy

DataFrame.xyz.ds_from_xy(**kwargs)[source]

Calculate point-to-point displacements from GPS coordinates.

The chosen scheme: displacement at [i] represents the distance from [i-1] to [i].

Parameters

  • **lat (scalar) – column label in the record DataFrame containing latitude coordinates along the route in degrees N (-90, 90). Must be numeric dtype. If a label is not provided, the parameter name itself is used.

  • **lon (scalar) – column label in the record DataFrame containing longitude coordinates along the route in degrees E (-180, 180). Must be numeric dtype. If a label is not provided, the parameter name itself is used.

Returns

point-to-point displacements along the route in meters.

Return type

pandas.Series

Assumptions:

  • Earth is a perfect sphere, with radius = pandas_xyz.scalar.EARTH_RADIUS_METERS.

  • The point-to-point distances are sufficiently short (so that latitude distortion and curvature have limited effects).
