CONCLUSION In the framework of road survey the use of GPS is necessary when the positioning has referred to an absolute reference system, which allow data representation in a mapping projection. In order to guarantee the continuity of the positioning, the presence of other sensors (odometer or platform) is still convenient (Schwarz, 1993, Wong, 1988). Furthermore, to maintain the compatibility with data collected during standard road survey, the extraction of a mile chainage should be considered. In general, the GPS derived mile chainage can be easily overestimated unless a more advanced procedure is implemented. With the approach adopted in this work, the mean difference observed between GPS and odometer chainage was within 3 meters. The performance of the RTCM satellite transmitted correction for differential positioning was positively evaluated along 50 km of highway. The positional accuracy level of the RTMC mode resulted comparable to the one relative to the post- processed mode. In consideration of the major operational advantages, the RTCM technique can be efficiently adopted for road surveys requiring meter-level positional accuracy. 6.
