thank you
Hallo sir, thanks for your video. It was really helpful. But, can you please tell me how to extract data from the other indices, like NDRE, NDVI, OSAVI, etc?
Hi Travis, thanks for the informative video! I found it really useful. Would it be possible for you to share the raw images?
Oye y este mi frijol esta muy seco e intentado todo incluso e echado liquido y e quitado partes secas me pidrias decir que hacer
one of the best videos on TH-cam
where do I get your beans friendly sir
best video on youtube to learn about grids in QGISxAgri.
Wonderful series, please make more video series UAVrelated.
Thank you!!
Thankyou I just dont want my different varieties of sweet potato to cross with each other as I especially bought different ones. I wasn't sure can I plant them together or if I have to keep them separate. Looks like they can cross but maybe not too easily?
Hi Travis, Good day. That's a handy tutorial, thank you so much. Making a video for this "Visible Spectrum UAV Imageries for Tree Quantification in an Urban Setting" will be very helpful for me. I am a novice in this field. Take care.
Actually informative video, unlike those made by curry people who make their food with feet. This is it!
Thanks very much for this video, you saved me a heap of time in not masking out soil areas with a manually drawn shapefile mask. This worked a treat!
Best tutorial outhere, gracias!
Both male and female looks same here in video. Can’t distinguish
Beans only have one kind of flower, they do not have separate male and female flowers. The flowers used as mothers are unopened (they would open the next day), and have not yet self-pollinated. The flowers used as fathers are the ones that have opened on the day you are doing the crossing
Thanks, this is helpful. My problem is that I can view the coordinates in the image properties details box, but I don't know how to use that to find a location on a map. The format doesn't seem to be any known type of latitude and longitude notation. If I copy it into the search bar of a map application it just gives an error.
Thanks a lot that’s very helpful!
@Travis Parker, Hi Travis, Could you please explain how to get DSM of plots? I have a drone image consisting of 7 bands (RGB, NIR, SWIR,...). Can I calculate/estimate plot volume in the absence of LIDAR data? If yes how?
You not provided DATA, how i can get Drone DATA???
Hey, what if i want to create a RGB of individual multispectral images captured from the drone, can it be done?
very helpfull! thanks a lot
Thanks for watching!
Thanks, and I want to ask how to line it up with timestamp ? thanks
I am not sure exactly what you mean, but pulling the time stamps from the EXIFs can honestly be really annoying. I was messing around with that in the command line a few months ago and it kept failing. I know there are some exif reader software options, but I remember stopping without pursuing it further at some point. Sorry to not be more helpful
Hey, we are neighbors, I know exactly where you took that image. I work here! Nice tutorial!
Excellent, very useful to understand the process.
Glad it was helpful!
hi sir, i have one doubt , can i calculate excess green from Landsat 8 image because i don't have drone imagery.
Hi, I would recommend just using the Landsat NDVI imagery! It will give you the same basic results, if anything it will be better!
Love the video too
What do you think of using osd instead of pix4d for rgb drone imagery and veg indices
What do you mean? Are you thinking of ODM?
I eat a lot of dry beans and prefer to grow them myself. A home breeding project to improve productivity of my favourites would be fun. Thanks for the idea. Also found your How to cross beans vid. Very useful.
Awesome! Yes, it is great that they are so easy to cross and select for anything that is interesting or useful!

Look me up at UC Davis!
OMG Thank you. I’ve been looking all Over for data. I didn’t even know sweet potatoes flowered. Now I’m interested in collecting seeds and cross pollination
Best 5 minute tutorial I've seen in months!
Thank you for your video. When is a new variety stabilized if you want it to become stabilized?
Actually I do not want that my runnerbeans cross polinate. Any ideas how to do it? Maybe how far appart should I plant them? And how to tell the insects that they are not allowed to cross polinate?
Hi, haha good questions! Runner beans are tricky... they are the only domesticated Phaseolus bean that will not self-pollinate, unless someone does it manually! The flowers of most other beans will self-pollinate in the absence of insects or people. So it will be tricky, sometimes we self-pollinate the runner beans by hand (this must be done in the greenhouse, where there are no insects). But to get seed, something needs to pollinate, and if you have many varieties in an area, the bees will move the pollen around! So I would say there isn't a clear distance that bees couldn't / wouldn't cross. You can self-pollinate if needed, otherwise, the further the better, if you don't want outcrossing!
Thank you so much for very helpfull video👍👍
Thank you very much for your videos, I hope you come back to provide more information about precision agriculture.
I used '(Threshold < 0.5)' as denominator for sDSM. However, the sDSM values were higher than the cDSM. How to calculate canopy height in such case? The images were acquired from corn trials.
Hi, I would use the information tool (little "i" symbol) to click around your field at areas of interest to check on that. I also use median soil values, rather than averages, in case you have furrows. But that would be a very strange pattern to have soil higher than canopies, I would check everything very carefully. If the plants are truly tiny, maybe < 3 weeks old, they might be too small to display properly, otherwise I would just thoroughly check everything
Parabéns pelo vídeo... seu português está muito bom.
I live in the north. I am interested in hybridizing sweet potatoes with their cold-hardier ipomoea cousins that are also tuber-producing: Ipomoea pandurata & Ipomoea leptophylla. Have you ever attempted such crosses, know if this has been attempted before, or know if anyone else is currently working on this? Thank you.
Hi Travis, awesome video; we did a flight with the M3M RTK and the output was a shrunk mosaic, it had all the elements on the field but they were smaller compared to satellite imagery, do you have any idea why can this happen? kind regards!
Were the images in the correct location? About what was the ratio or factor of shrinking? It could be an issue with reading in the geotags in the wrong coordinate system if it is a major deviation
Hey, great video, do you have a source for the crop index you used for canopy cover? Thanks!
Hi, Here is a source for the Excess Green Index, if you are interested: Woebbecke, D.M.; Meyer, G.E.; Von Bargen, K.; Mortensen, D.A. Color indices for weed identification under various soil, residue, and lighting conditions. Trans. ASAE 1995, 38, 259-269. I will also shamelessly advocate for our paper where we published this whole workflow, including the use of excess green! Parker, T. A., Palkovic, A., & Gepts, P. (2020). Determining the genetic control of common bean early-growth rate using unmanned aerial vehicles. Remote Sensing, 12(11), 1748.
I developed a software many years ago to do exactly this. GIS software is no longer an option when you get to the 1000s of plots. A field like show here would take just a couple of minutes with the custom software. For more complicated grids you could split it (and rejoin) at selected rows or columns. A key to a good fit is the transform/deformation type: I found bilinear is superior to projective.
We do this on thousands of plots regularly, but if the spacing is tight, it can be cumbersome to try to separate exactly, so I usually try to build a little extra spacing into the trials when possible, or just extract from the centers of canopies. If you have links to other helpful tools, let me know!

What is the success rate of doing Phaseolus crosses in the field vs. in the greenhouse?
For us, in the greenhouse on healthy plants with few pods, it is very high, maybe 95%+. Our Davis, CA field conditions are very hot and harsh on flowers/pollen, so I rarely do them there, but the ratio of success is much lower.
Agradeço. Qual a SUA porcentagem de sucesso ? Fizemos na faculdade com centenas de flores e todas abortaram.
Ahh, eu lamento ouvir isso. Para nos, na estufa, e quase 95%. Talvez 90%. Mas no campo, e muito menos, nao e comun ter suceso no campo, faz muito quente. Eu tentaria num lugar sombroso e fresco (nao tao quente), funcionaria melhor

Thanks so much for this detailed video! I'm starting my bean breeding at home this year and this helped so much! I've actually purchased your southwest gold and red varieties and will be backcrossing a lot to add in the "pole" trait to increase yield per sqft. Your focus on culinary varieties helped me realize I should breed the tastiest first! Good point! This is one of the best videos I've seen for bean breeding, keep up the great work!
Thank you! Plant breeding is wonderful, just about anything you want, you will get! All the best in your breeding adventures :)
