Aerial Mapping - DJI - ODM - QGIS

Ever wanted to take some Aerial Photos, stitch them together to make an orthophoto (georectified image like geotiff) and use the orthophoto for mapping a farm, a Council (municipality) reserve or park, a caravan park or any area to plan layouts, create contours or do measurements? This video shows some free and Open Source ($0) that can be used for this type of mapping.

The video shares a small project that uses a DJI Mavic 2 Zoom to capture aerial photographs, Pix4D for mission planning, Open Drone Map (ODM) to create orthophotography and 3d models and QGIS 3 and Meshlab to display some of the files that ODM creates.

I've used ODM to great effect in the past and I have been very impressed with the orthophotos ODM creates. For this project I wanted to see if flying two missions flown with an offset of about 20 degrees would create better images. So, this video shows how we went about the project and shows what was created by ODM.
