Back in March, Baker performed a Mobile LiDAR collection of a high speed rail corridor encompassing approximately 240 miles (opposing tracks along the same corridor). Now that the primary products have been delivered, I took an opportunity to create several screen captures of the collection. The two images below present different views of the same section of track.

Facing northwesterly, the screen capture clearly depicts the ability to capture a number of elements beyond the rail features. The handiwork of local "artists" is evident thanks to the intensity returns from the system. |

An opposite view from the image above shows the extent of overhead electric distribution, communication and fiber optic utilities. Also present are supporting guy anchors, a single mile post and other features necessary to develop engineering design drawings. |
The detail of information captured in a single collection is quite impressive. In addition to the planimetric feature extractions and track geometries, Baker developed a digital elevation model following constraint of the Mobile LiDAR collection.
Let me know what you think.
