This is a part of the source code of the following article "Map-Matching-Error-Identification-in-the-Absence-of-Ground-Truth" available at https://doi.org/10.3390/ijgi11110538
#O_VISTool V1.1 folder contains the source code for visualising any map-matched code in (folium and selenium based) an interactive platform, allowing users to interact.
Validation and performance assessment of the automatic error identification require ground truth data for the map-matched segments. Since the ground truth of map-matched segment data is not available with large-trajectory datasets, we apply visual inspection of the map-matched segments, applying the criteria of reasonable sequencing. To realize the visual inspection, I have developed an interactive, map-based tool called O_VisTool. The recorded GNSS points will pop up as red dots and map-matched segments are shown as blue markers with popup numbers. The tool tracks user interactions where the map-matched segments can be clicked as a ground truth error by a human inspector.
