Support for Drone Survey Data (.LAS files)

v5.0

Drone and Scan Data

.LAS files are a common format for lazer scan and drone survey data

- These files are often large, and very dense. Hard to load and work with

Deswik now support importing these files, and have an increasing number of tools to assist working with .LAS files

Import

Add files to be imported (supports multiple files) • Automatically stitches tiles together if grid output

Select outputs to create • Points • Surface • Grid • Nominate output layers

Whoa! I don’t need all those points…

Options for filtering on import make outputs more user friendly

• Settings tab • Limit import to polygon area • Specify min distance between

points • Decimate (filter) resulting

surfaces or grids

Cons

LAS files can be brutal on your hardware

Experiment to find the best balance

Take the time to find best settings for your data and use case – filter aggressively or use larger grid sizes

The aim is to minimize number of resulting points without sacrificing required level of detail
