How we check
our work.
Our current review process connects the drive, the processed roadway record and the report your engineers review.
Six checks, from the road to the report.
01 / Position
Our vehicles log GNSS and inertial data on every drive. Afterwards we post-process the vehicle’s path in Applanix POSPac, so each image and LiDAR point is placed from the corrected trajectory, not the live GPS.
02 / Time
Every frame and every point carries the time it was captured. You always know how current a view is, and which conditions a measurement reflects.
03 / Alignment
Our cameras and LiDAR are calibrated to each other, and the alignment is checked on every route before the route is accepted.
04 / Review
A reviewer checks each route’s colored point cloud before it is delivered.
05 / Traceable findings
Study results such as no-passing zones, curve advisories and roadside hazards are prepared to the standard your agency names. Each one links back to the imagery and measurement behind it, so your engineers can see why it was made.
06 / Field checks where they matter
Some decisions need more certainty than a capture can give, such as a bridge clearance close to its posted limit or a measurement near a design threshold. We say so, and recommend a field check.
What can limit a measurement.
A capture records what the vehicle could see. Traffic, parked vehicles, vegetation, distance from the road and point density can all limit what is visible or measurable at a location. We report these limits rather than guess past them, and we tell you up front which questions the capture can answer and which need a field visit.
LiDAR exports identify their coordinate reference. Studio’s export options include a projection file; agree the coordinate system and units your project needs.
The standards we work to.
We establish the applicable standards, edition and agency criteria for each project. Service pages cite specific sections of the 2023 MUTCD; FHWA’s current edition incorporates Revision 1. State adoption and supplements also matter. Reference sources include:
- Manual on Uniform Traffic Control Devices, 11th edition with Revision 1 (December 2025) (FHWA).
- Ohio Supplement to the MUTCD (ODOT, July 2026).
- ODOT Traffic Engineering Manual (July 2026).
- ODOT Location and Design Manual, Volume 1 (July 2026).
- Ohio Revised Code 4511.21, speed limits.
Outside Ohio, we work to your state’s MUTCD supplement and your agency’s own criteria, as on our studies in Indiana and New York.
