Welcome to today’s daily kōrero!
It doesn’t have to be me making the thread, first in first served. If you are here on a day and there’s no daily thread, feel free to create it!
Anyway, it’s just a chance to talk about your day, what you have planned, what you have done, etc.
So how’s it going?
Wow, that does sound fun! So many questions! Do you fly the UAV or does someone else do that? Is it more like a drone or like a light aircraft? What does processing the data involve?
I don’t fly them my colleagues do as they have their part 2 training. I process the data into ortho imagery, mesh, and point clouds and combine with LiDAR data and survey topographical data picked up at the same time as the flights.
This sounds amazing! What kind of tooling do you use to achieve this, and what is the output format? Who consumes this information once it has been refined?
UAVs and modern computers really do enable some incredible things.
yeah it’s pretty cool. We provide a few different deliverables. Mesh usually in a format the client likes e.g. .obj but our preference is Context Capture .3sm / .3sx files they just work nicely for a mesh. We also provide orthorectified/georeferenced imagery (.tif, .jp2, .ecw) and point clouds from the UAV flight. To check the accuracy of the UAV we post process the GPS data against Base station and Survey control we establish on site as well as using LINZ CORRS stations. It’s usually District Councils and Internal Engineers who use the data to design fixes for the road (Slips we do are usually on road corridors) so it’s not that glamourous haha. Recently we’ve also been doing Bridges and Road corridors to digistise into CAD from the UAV data and then design cycleways which is much more fullfilling.
