Dear Anne-Sophie, I see three issues here. a. Your ROI seems to be almost entirely empty. Let's try running with in your main config.json file ( just for testing): "roi": {

"y": 13000, "x": 2300, "w": 1500, "h": 1500 }

b. For the few tiles that worked the disparity range seems to be under-estimated. So I recommend to use: "disable_srtm": false, and / or use: "matching_algorithm": "mgm_multi", c. There's a wired error message in the logs during the triangulation step: terminate called after throwing an instance of

'GeographicLib::GeographicErr' what(): Longitude nand more than 60d from center of UTM zone 31

This could be due to some residual utm commands in the config.json. Please try removing the fields * utm_bbx *and* utm_zome. * Best, Gabriele

Unlike the processing with the Pléiade data, none of dsm.tif (in tiles folders) or dsm.vrt are calculated. Moreover some cloud.ply files are generated but I cannot open them and I have the following error message : « reading error (no access right ?) » when I try to open them with CloudCompare for example. I think the problem comes from the line « Timeout while running <multiprocessing.pool.ApplyResult object at 0x7fcffa9a7810> » but I don’t know if this is a problem with the parameters of the configuration file, with the data I use or an out of memory... I tried to launch s2p on the entire image but also on a smaller area. You can find the initial configuration file (config_s2p.json) and the result here : https://drive.google.com/open?id=1ZZGEfZRIIvFQiHitKdLK8Ga_rBHcKqBK Thanks for your help, Anne-Sophie — You are receiving this because you are subscribed to this thread.

Dear Gabriele,

Thank you for your very quick answer. I tried all your suggestions but it still doesn't seem to work...
I cannot remove the field "utm_bbx" (error message), so I just keep it empty, and I still have the problem with the triangulation step...
I don't understand why I managed to use s2p with Pleiade data but not with the Spot one using the same method and the same computer.. Are there some restrictions on the image to use ?

Thanks,
Anne-Sophie

Hi All

Is it Possible to process Spot 6/7 satellite imagery using S2P? Was the problem solved?
