This package contains the datasets and supplementary materials used in the IPIN 2016 Competition (Alcalá, Spain). Contents: Track3_LogfileDescription_and_SupplementaryMaterial.pdf: Description of the logfiles and supplemental materials. Track3_TechnicalAnnex.pdf: Technical annex describing the competition 01-Logfiles: This folder contains a subfolder with the 17 training logfiles and a subfolder with the 9 blind evaluation logfiles as provided to competitors. 02-Supplementary_Materials: This folder contains the Matlab/octave parser, the raster maps and the visualization of the training routes. 03-Evaluation: This folder contains the scripts used to calculate the competition metric, the 75th percentile on the 578 evaluation points. The ground truth is also provided in MatLab format and as a CSV file. Since the results must be provided with a 2Hz freq. starting from apptimestamp 0, the GT includes the closest timestamp matching the timing provided by competitors.
