Converting LIDAR Data to a 3D Modeled Landscape

Being able to see a landscape is one thing, but to digitally manipulate and process it opens huge doors to better understanding our environment. For this project, I wanted to take 2D maps one step further by combining geographic information systems and elevation data to create a 3D model of the Lubbock Lake National Historic Landmark. This began as a process for eventually printing this model and developing a tangible landscape for education purposes, but it could also be used for anything from construction planning to augmented reality experiences.

Many of the actions outlined below could be performed in GIS, but since my final goal was the creation of a 3D model, I decided to experiment with Agisoft Metashape Pro which can also export the final product in a variety of ways for continued use. I was happily surprised to see how perfectly it fit my needs and worked seamlessly without requiring plugins.

LIDAR — Light Detection and Ranging utilizes light to measure the distance between the mechanism of measurement (typically aircraft) and the surfaces below. This creates a data set measuring the variable elevation of an area that can then be utilized to create a Digital Elevation Model (DEM) which is what we’ll be doing here.

What you’ll need:

• Access to LIDAR data of your chosen subject.
• Agisoft Metashape Pro

I first downloaded the tiled lidar data from each grid that covered the Landmark site.
