Annotated scans improves survey practices

August 4th, 2019, Published in Articles: PositionIT

The ability to overlay georeferenced CAD lines and surfaces and annotate scans live in the field on the Maptek handheld scanner controller allows surveyors and geologists to improve their work practices. These new capabilities help close the loop between plans and as-builts by giving a live guide to survey coverage, ensuring all the required scans are taken in one session. The modern, digital approach enhances the interpretation of survey data and reduces the need for manual data entry and potential for mistakes arising from it. The new functionality has been introduced in the scanner controller of the Maptek R3 series 3D laser scanners. These tools assist surveyors to get out in the field, capture their data, make sure that data is meaningful and get back into the office quickly. The georeferenced CAD lines and surfaces can be imported directly from the Maptek point cloud processing package PointStudio, while the annotated scans can be extracted from the scanner controller and viewed and edited in the software. Users can add up to ten annotations to each scan, including CAD lines and text, view them in 3D and toggle the visibility on and off in the field.
