Cyface Measurement Analysis

Workflow

This workflow reads data from a set of gps data and accelerometer data CSV files. They need to be placed side by side in the input folder.GPS Files are named like: 00001_gpsPoint_2019-01-17_11-17-11.csvAccelerometer files are named like: 00001_aPoint_2019-01-17_11-17-11.csvThe first five digits are a running number. It follows the type of the file and a timestamp in the format yyy-mm-dd_hh-mm-ss.GPS files must contain the following columns:* type: The string "gps"* timestamp: the timestamp of the GPS point as measured by the measurement device in milliseconds since the 1.1.1970.* lat: The geographical latitude* lon: The geographical longitude* speed: The speed as measured by the GPS device in meters per second.* accuracy: The GPS accuracy in meters* mid: The identifier of the measurement* gpstime: The GPS time in milliseconds since the 1.1.1970Accelerometer files must contain the following columns:* type: the string "a"* timestamp: The timestamp of the acceleration in milliseconds sicne the 1.1.1970* x: Device acceleration in x axis direction in m/s²* y: Device acceleration in y axis direction in m/s²* z: Device acceleration in z axis direction in m/s²* mid: The identifier of the measurement Analysis This workflow reads data from a set of gps data and accelerometer data CSV files.
