Mobile MappingField Compilation

In 2006 Mobile Mapping efforts concluded survey on all limited-access highways, ramps, interchanges in the U.S. and Canada, totaling more than 190,000 miles.

In 2007 the focus was on completing the remainder of the national highway network (U.S. Highways & provincial highways) in the U.S. and Canada -- more than 165,000 of 385,000 miles completed.

MMV Technology

The science behind the MMV

Mobile Mapping Systems

Utilizes a van equipped with multiple cameras, a sophisticated positioning system and special image capturing software.

It is manned by a two person team - a driver and an operator.Sony firewire progressive scan cameras

with 1024-768 resolution and image frame acquisition time is up to 3 images per second

Data Size (Laser and Ladybug data not included)

An average of 1.88 GB per session (30 minutes of data)

30 GB per day (8 hours) per van

Mobile Mapping – Technical Specs (2/2)



A growing fleet of Mobile Mapping-equipped vans are active in the collection of imagery and high-quality positional information.

The resulting data is used in both manual and automatic processing for the population of signboards, lanes, speed limits, elevations, tolls, route names, etc.



Mobile Mapping technology includes:

Stereoscopic cameras to allow for three-dimensional measurementsOmniStar Differential GPSInertial GPS System for gathering data in tunnels and urban canyonsLaser Scanners allow for 3D reconfiguration of the structures that are passedLadybug Cameras provide 360-degree image-gathering

Road Asset Shapefiles

Build and Deliver Road Asset Shapefile Layers, Road Asset Images and AVI Video LogThe scope of road asset collection includes capture of the x, y, z location of all visible features included in the specified classes, along with applicable attribute information listed. Each class of asset will be provided as an individual Shapefile dataset.Examples – fire hydrants, signs, edge of road, traffic lights, guard rails, etc.

Road Asset Images

Individual geo-referenced image frames


AVI Video Log


AVI Video Log

Running-video image, in .avi format, converted from the right-hand 90-degree-angle frames*

AVI can be from different camera or angle but 90 degree facing structures is most common

Short Example

LBRS

Location Based Response System



Two primary outputs:Birds Eye Mosaics(BEMs) are produced that render the vertical images into a horizontal imagery layer.Vertical Event Framesare used as resources/references for editing purposes.


3d Bread Crumbs

Each point contains x,y,z data Can calculate slopeCan calculate actual distance


Address Verification

The camera captures the house with featuresThe GPS on the van captures the locationUtilizing both of these an address point can be placed where desired (front door, driveway, etc)


LRS – Road Inventory

Road inventory system that contains actual mileage

The software supporting Mobile Mapping efforts include CarMapSystem—an equipment-monitoring program—and the Data Acquisition Management Program (DAMP) Day—that tracks van progress

against the scope of work.
