SpeedCalculator

This transformer uses points with timestamps to produce 2-vertex lines with two new attributes - _length expressed in meters and _speed in km/h.

The transformer requires time in hh:mm:ss format as a parameter. If time attribute has milliseconds (hh:mm:ss.ddd), they should be truncated before features enter the transformer.

Input point coordinates should be in meters. Use Reprojector transformer if source points are in lat/lon or other non-metric units.

The transformer works with one set of points (one track).

In order to run the attached example, you'll need to download Magellan_Track_File_custom_format.

The screenshot below shows my way home measured with Magellan GPS receiver. The log file (see the attached archive) contains 98 points.

After creating lines, buffers were generated around each segment, and then Dissolver was used for creation of a continuous feature.
