Mobile Mapping System Accuracy

Data available are: 1- GPS Differential Correction Strategy 2- Speed 3- Lane 5- Discrepancies 6- Planimetric Error. The data were acquired using a Mobile Mapping System (MMS), which enabled the capture of highly precise geometric and positional information of the road network.

Data collection was conducted in both directions along the M-611 road at speeds of 40 and 60 km/h, ensuring comprehensive coverage of the study section. To guarantee accurate georeferencing, three methods were applied: Z60, based on a local GNSS differential correction; VRS, employing an RTK system with a virtual reference station provided by the Spanish National Geographic Institute (IGN); and SINGLE, utilizing RTK-mode data from the nearest permanent GNSS station managed by the IGN.
