Close-range Photogrammetry
Not drones, but still cool! You can use the same structure-from-motion software we use to process drone imagery to create 3D models from overlapping photographs of an object.
Image Coregistration in Agisoft Metashape
While most photogrammetry projects may only need data from one point in time, there are many instances where you want to track change over time. With high-resolution, 3D drone imagery, coregistering the 3D models and image products from different time periods is very important, but can also be very challenging. This exercise walks through a few different approaches to coregistering 3D models and orthomosaics in Metashape.
Manually Aligning Photos in Agisoft Metashape
Metashape is great when you have well-behaved photos. When you don’t, it can be super frustrating. While not every image set can be successfully aligned in Metashape, there are some strategies for manually aligning photos if they don’t want to align.
Post-Processed Kinematic Survey Data with Emlid Studio
Post-processed kinematic (PPK) surveying is an important technology for achieving high-accuracy, high-precision location data for drone mapping missions. In this exercise, we look at how to post-process data collected with an Emlid Reach RS+ base station and rover setup using Emlid Studio.
Introduction to Agisoft Metashape
Agisoft Metashape is a digital photogrammetry software application that is used for turning drone-collected photographs into high-quality maps and 3D models. This exercise will walk through the basics of how to use Metashape.
USDA Lidar Drone Grant
The University of Idaho’s Drone Lab was awarded a USDA NIFA Equipment Grant for $110,000 to fund the purchase of a drone-carried lidar system to be used for research and teaching in the fields of agriculture and natural resources at UI and with partners.

Automating workflows for processing and classification of drone imagery to monitor grassland conservation easements
The University of Idaho’s Drone Lab has worked with the Montana Chapter of The Nature Conservancy to develop and refine workflows for automated processing of drone imagery into indicators of ecosystem health.
Mapping the Thermal Flow: Best Practices in River and Riparian Temperature Monitoring with TIR Imagery
We are using thermal infrared (TIR) imagery to map thermal profiles in rivers and riparian areas at the reach scale in the upper Big Creek drainage of Central Idaho.
Structure from Motion with Historic Aerial Photos
LEARNING Structure from Motion with historic aerial photographs. Modern photogrammetry software is a powerful tool for orthorectifying and merging historic aerial photographs into digital map products that can be used in GIS maps and analyses. The concepts of photogrammetric mapping can be applied to any…
