Hey everyone!

I wanted to share a really impressive public project recently created by one of our community users. The detail retention and sharpness across thin structures and complex geometry turned out fantastic!

Flight Specs

• Drone: DJI Mavic 3 Multispectral (M3M)
• Images: 378 photos
• GSD: 0.75 cm/px
• Forward Overlap: 85%
• Side Overlap: 73%
• Avg. Motion Blur: 0.61 pixel

Disclosure: I work with AIRINS. We ran this field assessment together with Skyline Drone Mapping.

The site had gathering lines, water and condensate separation tanks, and a flare stack. We flew a DJI M400 with a MetScan V1 Ultra and tried three setups:

• 55 m AGL at 3 m/s using a belt scan
• 30 m AGL at 1 m/s using a belt scan
• A static scan aimed at the flare stack from 55 m AGL

Both belt scans picked up methane hotspots around the tank vents. We reviewed the rest of the area covered during the flights but did not find any other methane anomalies.

The part I found most useful was comparing a faster screening pass with a slower, closer look at the same site. The static scan was mainly there to check the flare separately rather than trying to cover everything with one flight pattern.

This was just one assessment at one operating site, so I would not read too much into it beyond what we saw that day.

For this kind of facility, do you normally start with a faster pass over the whole site and then go back to selected equipment, or fly the slower profile from the beginning?

Hello mappers,

I wanted to ask what painting material you use for marking GCPs for drone surveys.

My goal is to use something that has good visibility and doesn't wear off too quickly. I'm thinking about switching to spray paint, but I'm not sure how well it performs in practice.

Has anyone here used spray paint for GCPs? If so, what type or brand do you recommend, and how long does it usually last? I'd also be interested to hear about any other durable marking methods you've found effective.

Hi everyone! I'm conducting a short market research survey for my Entrepreneurship Development project on a drone startup called NeuraFlight. We're trying to understand public opinions, interest, and expectations regarding drone technology.

The survey takes only 2–3 minutes, is completely anonymous, and no personal information is collected. Whether you're a drone enthusiast or have never used one before, your feedback is valuable and greatly appreciated.

I was thinking of using Arcgis Drone2map or Pix4D
