00:34:34 suz: Has anybody heard from Steve Greb? It looks like this webinar isn’t happening now. 01:05:33 Gongliang YU: hello 01:06:15 Merrie Beth Neely: hello Gongliang and everyone 01:09:31 Joseph: Hello, I am Joseph Mlotha, RPI New York, mlothm@rpi.edu 01:09:49 Merrie Beth Neely: Hello Joseph, welcome. 01:23:09 Enrique Montes: Hi. It is a bit hard to hear the presenter. 01:23:41 Merrie Beth Neely: https://blog.vito.be/remotesensing/multi-spectral-camera-under-a-low-cost-drone 01:23:53 Merrie Beth Neely: Enrique try turning up your volume 01:24:01 Enrique Montes: it is 100% 01:24:50 Merrie Beth Neely: I apologize for that. HIs is too and he says he is very close to his mic. 01:25:20 Abu 2020: What is the best time to fly the drone and start capturing images? 01:29:31 Merrie Beth Neely: This recorded webinar will be available for viewing online in a day or so here: https://www.geoaquawatch.org/geo-aquawatch-webinar-series/ 01:32:30 WHH Tobias B: is icor4drones open source? 01:38:08 Chui Zeng: what is the method used to estimate TSM? 01:39:50 Maira Bezerra: I am also interested in learning more about the method used to estimate TSM, or other water quality parameters. 01:42:06 Thomas Heege: Hi Vito-team, how stable is the stability of calibration / of the used sensors over the drone flight (e.g. compared calibration before and after flight)? Thanks 01:43:09 Chui Zeng: follow up to Thomas, what is the material of the reference panels? 01:43:10 Merrie Beth Neely: If anyone has any additional questions please type them here or unmute yourself and ask Liesbeth or Robrecht directly 01:43:16 Joseph: Are their examples for Africa or Sub-Saharan area in-land lakes? 01:43:38 Abu 2020: Can your methodology be applied in case there is mixed contaminant types? 01:44:38 Bernard: How do you make sure you don't get reflectance from the bottom of the lake bed?? 01:45:27 Karan Behar- iSenses: Will hyperspectral imaging provide more insights as compared to multispectral camera? 01:45:50 CBAYONA: with the weight of the cameras, how much is the flight autonomy of the phanton? 01:47:22 Vikram Gulecha: How affordable is the technology and what benefits it can provide to the water resources department? Do you intent to launch in India and when, if yes? 01:48:14 Karan Behar- iSenses: For TSM calculation what are the ground truth methods? 01:48:52 Abu 2020: Did you try to modify/recalibrate your imaging system to accomodate field measurements? 01:49:59 Bernard: Have you tried stitching drone images over large lake? 01:49:59 Abhishek: You saw Sentinel 2 images many times. Is there any comparison you performed between Sentinel 2 reflectance versus your drone derived reflectance? Any plan in future to have a synchronous data collection? 01:50:18 Philipp M Grotsch: following up on Karan Behar's question: have you experimented with hyperspectral spot- or line-scanning measurements (as opposed to full 2D imaging)? 02:00:32 Andrea Vanderwoude: Thank you. Excellent talks! 02:00:38 Abu 2020: Thanks for this great session 02:00:45 Karan Behar- iSenses: Godspeed
