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.

MIRE

• Capture and Maintain inventory elements (Change Detection)

HPMS

• Meet Federal requirements = Funding

ASSET MANAGEMENT

• Enterprise Management system in process

LEVERAGE

RELIABLE GIS CENTERLINE

• Maintaining and updating LRS Centerline

FEATURE EXTRACTION

• Consistent and reliable extraction

PORTABILITY AND SHARING

• Web based user access to data

HPMS

• Beyond the historic IRI submissions – Now Performance Measures

SAFETY

• Curve, Signage, Crash Database

ARAN POSITIONING DATA: GPS & DMI

• System: Applanix

• Internal Measurement Unit (IMU)

• Dual GPS 12-channel Antennas

• The DMI, mounted on the left rear

driving wheel, utilizes a precision

optical shaft encoder

• Accuracy: ±0.02% of the linear

distance traveled

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
