How are you protecting your pipeline assets? With access to the latest geospatial technology,  Caltech provides oil & gas clients with solutions to manage their pipeline assets and pre-emptively plan to mitigate incidents and disasters before they occur, ultimately saving time and money. 

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.

The Temporal Lidar Change Detection (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 temporal lidar change detection 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 Imagery
  • Real Time Kinematic (RTK) Global Navigation Satellite Systems (GNSS)
  • Static GNSS
  • UAS


Caltech won a David Thompson National Geomatics Award for TLCD and GNSS monitoring of the Old Fort landslide natural disaster near Old Fort, British Columbia.
