Data processing
– 4 profiles each track
• track axis
• field and railway side
• ballast loupe
– > 80 km/h
– standard > 1:250
– GPS-controlled
data collection
digital video-documentation
Penetration depth
down to 4 m
– Viewer and print program for Radar data
– 2D-program with
• layer boundaries
• direct samples
• track geometry (rail hights)
• digital video
• databank
• all data on DVD or harddisk
• crossprofile
• compatible to AutoCad
• consulting
• report
– Proposal sampling program
– Carry out samplings
– Representation of sampling
graphics inside radargrams
for calibration
– Scanning of all visible layers
– visual raw diagnosis
• Contineous discription of all profiles for example:
– Ballast slumping
– troughs
– contaminated layers
– layer boundaries
– track bed compaction
– moist areas
– sinkholes
– metre precise assignment with
track kilometres
and GPS
– Implementation of:
• buildings
• kilometre-jumps
• rail hights
– Raw data
• filtered
• magnified
• synchronized
