UJIIndoorLoc Database

The UJIIndoorLoc is a multi-building & multi-floor database for indoor localization related problems based on Wireless-LAN fingerprinting technology. This database has been used as the core of the indoor positioning system of the Smart Campus aplications of the Universitat Jaume I.

WLAN Fingerprint-based positioning systems are based on the Received Signal Strength Intensity (RSSI) from detected Wireless Access Points (WAP). Commonly, two phases are needed: calibration and operation. In the calibration phase, a radio map of the area where the users should be detected is constructed. Later, during the operational phase, a user obtains the signal strength of all visible WAPs that can be detected from user position and the positioning system estimates the position using the information provided by the user and the radio map.

This database contains 19936 samples for calibration and 1111 samples for validation/testing which were taken in three different facilities of the Universitat Jaume I by more than 20 users. We expect that the UJIIndoorLoc database will become the reference database to compare different indoor localization methodologies. In addition, this database can also be of interest in other related research fields.

UJIIndoorLoc-mag Database

Indoor localization is a key topic for mobile computing. However, it is still very difficult for the mobile sensing community to compare state-of-art Indoor Positioning Systems due to the scarcity of publicly available databases. Magnetic field-based methods are becoming an important trend in this research field. Here, we present UJIIndoorLoc-Mag database, which can be used to compare magnetic field-based indoor localization methods. It consists of 270 continuous samples for training and 11 for testing. Each sample comprises a set of discrete captures taken along a corridor (or an intersection) with a period of 0.1 seconds. In total, there are almost 40.000 discrete captures, where each one contains features obtained from the magnetometer, the accelerometer and the orientation sensor of the device.

Detailed information regarding this database can be found in the IPIN2015 contribution cited below.

The database can be dowload from UCI repository.
