We provide Precision Mapping for a 3D World™


high-accuracy-rail-corridor-mapping Railways, High Speed Rail, Commuter Rail, and Light Rail are an important part of today’s transportation infrastructure, enhancing the connectivity of people and communities. Safety systems are a high priority component for safely moving passengers and products. Precision Mapping is an absolute necessity. From New Rail Routes, Expanded Rail Networks, Positive Train Control, Public Safety, and Asset Management, ACA specializes in providing 3D Precision Mapping and Geo Data Bases to support decision making.

Our Mapping Applications cover:

  • Rail Corridors (Elevated, Ground Level, and Below Ground)
  • Tunnels
  • Bridges
  • Stations
  • Rail Yards
  • Multi Modal Centers

…including the integration of GIS asset information.

ACA’s innovative approaches include Aerial LiDAR, Mobile LiDAR, Static Scanning, Digital Orthos, Digital Photogrammetry, Geo Referenced HD Oblique Video, Ground Survey and BIM Scanning, all completed with FRA Safety Compliance. All 2D and 3D projects are delivered individually, integrated into an ACA developed Geo Data base, or into a data base of your choice.

Connect with ACA for your next rail transportation project. From Light Rail, Commuter Rail to High Speed Rail our dedicated experts thrive in providing the very best 3D mapping products and services.
