Introduction to Hanson
Established in 1954, we’re an employee-owned, full-
service engineering, planning and allied services firm.
Organized into seven markets:
– Energy & Industry
– Telecommunications
– Government
– Railways
– Aviation
– Department of Defense
– Infrastructure
Geospatial Imaging Unit
Vehicle-mounted mobile spatial imaging system
Economical, Accurate, Safe
– Data acquisition at highway speed
– Survey mapping grade accuracy
– Keeps workers off pavement
– One pass approach to projects
Mobile Data Collection Summary
Digital photo extracted and linked for each position
Data delivered and extracted in GIS database
Change detection for multiple year inventories
Speed of inventory far greater than conventional survey
Mobile Data Collection Process
Route driven adjacent to inventory items
Coordinates, heading, vehicle pitch and roll, photos
Processed in office manually by technicians
Locations of items triangulated using digital photos
Collected info stored in database file
Users and Uses
Geared towards survey, GIS, and infrastructure
managers, as well as spatial data collection service
providers (transportation, utilities, energy)
Possible Areas of Focus
Roadway Corridors
– Pavement History
– Lighting & Striping
– Road Surface Inventory
– Sign Inventory
– Water, Gas, Power, Sewer Inventories
– Design and Location Studies
Utilities and Energy Transmission
– Asset Inventory (location, heights, condition)
– Database Preparation
– Digital Photos of Assets
– Photo Log of Site Conditions
IDOT Outdoor Advertising Control
Support Services
Illinois Outdoor Advertising Project
Acquire inventory
Permit application evaluation
Records review & scanning
Review of illegal signs
Related sign control tasks
Illinois controlled routes = 16,000 miles
Estimated 19,000 signs next to controlled routes

Data Extraction
Location (X,Y,Z) extraction from user interaction
Measurements from user interaction
Attribute logging (types, conditions, etc.)
For GIS, points, polylines and polygons supported

Environmental Surveys
Surveys for Transportation Projects
Water resources - wetlands, streams, rivers, lakes
Cultural resources – historic structures & archaeology
Sensitive noise receptors
Natural resources – T&E species, trees & natural areas
Public parks and recreational areas
Agricultural lands
Hazardous waste / contaminated property
Example Project – I-90 Tollway
Reconstruction of Jane Addams Memorial Tollway (I-90)
16.8 miles
Addition of one mainline in each direction
Bridge widening over Mosquito Creek and Coon Creek
Overpass roadway bridge work at 10 cross roads
Example Project – I-90 Tollway
Example Project – I-90 Tollway
Example Project – I-90 Tollway
Example Project – MCORE
MCORE (Multimodal Corridor Enhancement)
Cities of Champaign and Urbana, University of Illinois
Urbana-Champaign, Champaign-Urbana Mass Transit
District
3.0 miles of streetscape improvements
Create a more balanced and complete street network
Example Project – MCORE
Multimodal Corridor Enhancement Project

Example Project – MCORE
Advantages and Disadvantages
Advantages
– Saves time vs. conventional
– Safety
– Accuracy
– Permanent record
Disadvantages
– Limited to existing roads
– Requires manual extraction
& processing
– Initial high cost
Future Applications
New technology (LIDAR, off-road capability)
Habitat surveys
Feasibility studies & Phase I planning
Noise receptor selection & modeling
Public involvement / engagement
