This dataset is collected at KAIST, Daejeon, and KAIST by ISILAB to research seamless indoor-outdoor detection. The collecting device is a Raspberry Pi 4B+ with touchscreen UI connected with a Pmod Nav module and a PmodGPS. This collection has a rough three-month time span, which mitigates the specific time-specific bias. Further, in the collection, we also swap the wiring to simulate the device bias. The dynamic calibration is not applied to the dataset; searchers may choose to apply the dataset or not. The header contains the following "timestamp, indoor, gyr.X, gyr.Y, gyr.Z, acc.X, acc.Y, acc.Z, mag.X, mag.Y, mag.Z, pressure, tempB, latitude, longitude, altitude, hdop, pdop, vdop, fix, satellites, index, snr_1, snr_2, snr_3, snr_4."  We retrieve this dataset from our database for more straightforward utilization. The label indoor is a boolean index to indicate whether the user is indoors or not, which is a manual label at collecting time.
