Lidar Change Detection for pipelines

Caltech’s Temporal Lidar Change Detection (TLCD) services assist our clients in making informed decisions ultimately saving them money and time.

Caltech is a full-service geomatics solutions provider, and our surveying specialists can complete supplementary monitoring surveys to identify small changes. Providing the data in
easy-to-navigate 3D web-based viewers allow for collaboration within our clients’ organizations by representatives of all technical skill levels.

TLCD analysis applies to pipelines, geotechnical and geohazard monitoring, and natural disasters. Temporal analysis identifies if there is ground movement and where it is occurring, and quantifies how much movement has occurred. It can be used to identify erosion or accretion along water courses and identify anthropogenic changes within or near to pipelines and other critical infrastructure.
The initial phase of any TLCD project includes a baseline mobile mapping data collection and ground survey to verify the quality and accuracy of the remotely sensed data.

Subsequent data collection occurs at regularly scheduled intervals and is compared to the baseline data set.

Caltech’s TLCD program has helped many oil and gas clients manage their pipeline assets and pre-emptively plan to mitigate incidents and disasters before they occur.

Technology used:
+Mobile Mapping Systems (MMS) including Lidar and 3-Band Color Imaagery
+Real Time Kinematic (RTK) Global Navigation Satellite Systems (GNSS)
+Static GNSS
