LiDAR- Laser Imaging Detection and Ranging

A solution applied to lineal projects


For various social, political and economic reasons, in some areas of the country, some communities have been showing their dissent to projects of the hydrocarbons sector. It is increasingly difficult to access the properties to carry out the required engineering and environmental studies to undertake the design and subsequent construction of the project.

In this context, it became necessary to design a pipeline that would transport the crude oil from the eastern sector of the Paz de Ariporo municipality to connect to the Bicentennial pipeline (OBC). The projected length of the pipeline was 146 km and the design works, specifically the topographic survey, were to be carried through in 9 villages and more than 85 properties.

For all of the above, the designs had to be made by minimizing the intervention and the presence of the personnel in the areas, in an attempt to reduce the community’s discomfort during the early stages of the project.


Offer the customer the option of using the LiDAR technology for the topographical survey of the 7300 ha of the project’s target area. The LiDAR allows us to circumvent the conventional topographic survey in most areas of the project. With the airborne LiDAR survey, which lasted approximately two days, it was possible to obtain the digital model of the terrain, and avoid entering the premises to carry out the topographical survey. This task would have taken months to be completed, and there was no certainty whether access could be obtained to all the properties in a number of sites.


It was possible to design the pipeline with a good-precision terrain model and a 15 cm / pixel-resolution image in the 500 m mobility strip. In addition, from the digital model it was easier to delimit the flood areas, which allowed supplementing the geotechnical design of the pipeline.
