What is the GSD being calculated as ?
I am not sure where to find that info, but looking around, I could find that the odm_orthophoto_log.txt file has written:
From the picture I would think it is a higher resolution than that, maybe 10cm/pixel. THe original photo has 1cm/pixel
If you run the job to completion, the Report.pdf will have the GSD as calculated.
Thanks! It reports an average ground sampling distance of 0.9cm.
But why has the resulting orthophoto a resolution of 10-20 cm/pixel when the calculated GSD is 0.9?
How can I get a high-res orthophoto?
This is equivalent to 5cm/px, which is the default (the “20” here means 20 px/m → 1/20 * 100). Try setting
1 (and disregard
Not quite, you can set it, but it will be capped to GSD (it will not go lower than 0.9 cm/px in this dataset).
Yep, like Piero said. If you’re using Lightning, set it to 1cm/px, or even 0.1 since you’re processing locally. It will then go as low as the actual calculated GSD, so 0.9.
