Mapping
Matters
We collect data on topography, soil
composition and environmental
conditions, both on and offshore. We
organize the acquired data and add
value through processing,
interpretation and visualization.

LESSONS LEARNED - TBD
Gravel Roads
• Remote locations with poor cell coverage
• Loose stones can damage ARAN equipment
• ARAN is a 2wd vehicle that could get stuck in soft muddy areas
• Is there a spot for the ARAN to turn around at the end of routes?
What to do?
• Design cover for front enclosure to protect roughness lasers from loose gravel
• Equip crews with satellite phones to ensure they don’t get stranded
• Use a 4wd truck for collecting gravel/dirt roads
