The California Department of Transportation has designated a stretch of freeway in San Diego as a test bed for anyone that wants to demonstrate the capability of their mobile mapping system. One company that recently completed a very successful trip to the area is Terrametrix, LLC. A more detailed report is available on their website.
Terrametrix uses the Streetmapper mobile mapping system from the U.K. based 3D Laser Mapping. The headline for the report is that Streetmapper achieved 1cm accuracy – demonstrating what I think would have to be considered engineering grade results.
I continue to hear statements from knowledgeable experts who are on both sides of this issue. Both assure me that it is just not possible, or that it is. The devil is always in the details, but if you want to find out more I am sure the folks at Terrametrix would be glad to discuss it with you.
I am going to keep this short today as I am already late due to a problem with my hosting service not being online. I am sorry for any inconvenience.
