    • Smartphone Data for Development of Indoor Localization Apps

    Metadata Updated: September 30, 2025

    The PerfLoc Prize Competition (https://perfloc.nist.gov) was developed by NIST during 2015-2017 and was run during 2017-2018. The Competition was concluded with a single winner on May 16, 2018. However, NIST believes the data collected for the PerfLoc Competition is still of value to the R&D community, because there is still room to develop better signal processing and data fusion algorithms that would fuse various types of smartphone data collected in this project to develop indoor localization apps with higher localization accuracy. For that reason, NIST continues to make the PerfLoc data available to the R&D community.One thing has changed compared to when the PerfLoc Competition was running in 2017-2018. It is no longer possible for app developers to upload the location estimates generated by their apps at the PerfLoc website for performance evaluation purposes and to get statistics of localization accuracy. However, the PerfLoc data is still useful, because there is training data with ground-truth location annotation that would be useful to anyone wishing to develop indoor localization apps and getting an idea of the performance of their apps.“There are a total of 14 files that can be downloaded from this web page (see below). The descriptions for these files can be found at the relevant PerfLoc web pages (https://www.nist.gov/ctl/pscr/perfloc-user-guide and https://www.nist.gov/ctl/pscr/perfloc-data.”
