# RiPrecision RiPrecision optimizes the trajectory based on pointcloud observations. To access RiPrecision, navigate to Tools->RiPrecision. Select the trajectory and laser device in Adjust mode:

Use automatic features:

Use the default RiPrecision UAV parameters:

In most cases, use the non-rigid with translation adjustment mode:

RiPrecision will display a report, which indicates the trajectory adjustment applied. Ensure that excessive adjustment did not occur. Adjustments in position should typically be less than 0.10 m, while adjustments in attitude should be less than 0.20 degrees:

Note that the result of RiPrecision is an optimized trajectory, so now the project has two trajectories:

Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.phoenixlidar.com/3rd-party-software-documentation/bathymetric-lidar-processing-in-riprocess/riprecision.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
