Data structures

Basic preamble for every log:

• ID - category ID from categories file (more).
• Name - category name from categories file (more), otherwise manually inputed name
• User - identification string from preferences (issue #6).
• TimeStamp - unix timestamp (convert with this). Not unique. Example: 1409513090236
• DateTime - Human-readable datetime. Not unique. Example: 16.07.2015 22:00:11

Cell (GSM/3G) log structure

• NetworkGen - current network generation (2G/3G/4G) (more)
• NetworkType - current network type (EDGE/GPRS/UMTS/HSPA...)
• Active - 1 if this Base Station is the active one, 0 otherwise.
• MCC - Mobile Country Code (more).
• MNC - Mobile Network Code (more).
• LAC - Location Area Code (more) for 2G/3G. Tracking Area Code (TAC) for 4G.
• CID - Cell ID (more) for 2G/3G. Physical Cell Id (PCI) for 4G.
• PSC - Primary Scrambling Code for 3G network (0..511). Cell Id for 4G.
• Power - RSSI for 2G. RSCP for 3G. RSRP for 4G.

Supported sensors columns (user defined)

• Accel_X - acceleration by X-axis in m/s2
• Accel_Y - acceleration by Y-axis in m/s2
• Accel_Z - acceleration by Z-axis in m/s2
• Linear_X - linear acceleration by X-axis in m/s2
• Linear_Y - linear acceleration by Y-axis in m/s2
• Linear_Z - linear acceleration by Z-axis in m/s2
• Azimuth - angle between the magnetic north direction and the Y-axis, around the Z-axis (0 to 359). 0=North, 90=East, 180=South, 270=West
• Pitch - rotation around X-axis (-180 to 180), with positive values when the Z-axis moves toward the Y-axis.
• Roll - rotation around the X-axis (-90 to 90) increasing as the device moves clockwise
• Magnetic - measure the ambient magnetic field in the X, Y and Z axis. Value in micro-Tesla (uT).
• Gyro_X - Angular speed around the X-axis in radians/second
• Gyro_Y - Angular speed around the Y-axis in radians/second
• Gyro_Z - Angular speed around the Z-axis in radians/second
• GPS_Lat - Latitude, in degrees
• GPS_Lon - Longitude, in degrees
• GPS_Alt - Altitude above the WGS 84 reference ellipsoid, in meters
• GPS_Accuracy - GPS fix accuracy as the radius of 68% confidence, in meters
• GPS_Speed - Speed, in meters/second
• GPS_Bearing - Bearing is the horizontal direction of travel of this device, and is not related to the device orientation, in degrees
• GPS_FixTime - GPS fix time in unix timestamp
• Audio - Noise level, in decibel.
