When using the scanner to collect data over a large area, divide the total survey area into sections. This improves the efficiency and accuracy of data processing and makes the survey area easier to manage. Divide a large survey area into several small sections. It is recommended that data collection for each planned section take no more than 25 minutes.
When several data sets need to be stitched, two adjacent sets require at least 3 common control points that do not lie on one straight line.
