Would you be able to make the course material available in PDF? This would be of great help to the learning of people who are revisiting your wonderful videos. Thank you very much from Brazil.
You are a life savior, very grateful from Brazil!
could you please provide us with the slides as a PDF in the description box??
Hello. Thanks for your interest. You can access the slides here: docs.google.com/presentation/d/1qASO9RqQF_90rQodVeNMLyA8hUHomzpe-Kk2XmuwWt4/edit?usp=drivesdk
Hi Isaac, are you in this video??
Yes, this is me!
@@IsaacUllah_GIS_Tutorials Fantastic! I live about 30 kilometers from this place . That drone you use in this video? Thanks
@@modellazioneidraulicagis Wonderful! It is not a drone, actually, but a 360 camera on a long boom pole. I do my field work nearby in the vicinity of Bova. I love this whole region!
Very interesting! Would it be possible to get the pointclod of this capture?
Thanks for your interest. At this moment it is not yet possible to provide access to the data. We will eventually publish all data in an open repository once we have finalized analysis and have ensured requisite sharing permissions from property owners.
😊😊😊😊😊😊
Hello, where can I download the data to practice your tutorials? Can you share the link, please? thank you.
Links are in channel description.
@@IsaacUllah_GIS_Tutorials thank you so much
this is so useful
Very generous of you to share these videos, they have helped me a lot!
Thank Dr Isaac for this. It's very valuable. Kindly what's the linear dotted feature that appear in 57:17 running diagonally south east corner after you zoomed in?
Not sure. Probably a tiling artifact in the assembled DEM.
While I was probably wanting to do more quantitative analysis you show shome really neat tricks! Thanks
I have been struggling to understand this for long time now….. Thank you for this detailed video!
Thanks for the video, it’s very useful!
Amazing lecture... Thank you.
Thanks Isaac!
Can you please help me debug a grass 7.8.6 problem?? I am trying to use raster map calculator. The expression is Beerslaw= (Landuse_Final@PERMANENT.recode.mode == 42)*0.46 ... Landuse_Final have category 42. It gives me Invalid map <Landuse_Final@PERMANENT.recode.mode> Parse error ERROR: parse error If I provide space i.e. Beerslaw= (Landuse_Final@PERMANENT .recode .mode == 42)*0.46 it gives me syntax error Parse error ERROR: parse error It will be very nice of you if you can help .
You added suffixes to the mapset name PERMANENT. You can't have those "." in a Mapset name.
Hey, i been watching your videos and are very helpfull. I have some questions anyway, in this case, when i try to do the 3D visualization, the program shuts down and close. I dont know what could be happeninng. Any clue?
It's hard to diagnose without additional information. Usually you are missing a dependency or run into memory or graphics card issues. I suggest you join the grass users mailing list on grass.osgeo.org and ask there with more details.
Great video sir, that was very helpful.
Is this written Netlogo tutorial available online somewhere?
It's part of the open textbook by Romanowska, Crabtree, and Wren.
grass is really user unfriendly...like a messy kitchen that cookware & food are everywhere but you cannot prepare a dish in an organized & logically meaningful way thru this kitchen to satisfy the need of required output by your boss...
I think it's all about what you are used to. I personally have no issues with GRASS. It's a bit different than other GIS software interfaces, but it aligns better with my personal approach to GIS.
Please provide a link in this video description to the previous video that explored how to set up an outline in google docs. Thanks.
dear sir,how can i get the shapefile of the particular area i am interested in rather than downloading the full tile which includes some part of the ocean like in this video?
You can't download shapfiles from here, only raster tiles.
What gear was used? Any gimbal or IMU?
Device has IMU on board. It was put on a tripod.
hello, is it possible to perform controlled classification using lidar data ? Can we get the results of the accuracy analysis of the classification?
Thanks
Please try and answer peoples questions. For every question there are dozens of us with the same questions. Otherwise, why post at all?
Please read the channel description. These videos are for students in my classes, and I make them available to others as general part of open science. If you ask very well phrased short questions, I sometimes can answer them, but not always.
thank you
Dude, do you have some other channels or something? Or does your work relate making tutorial videos? For some reason your voice is just too familiar, but I dont know from where, since I'm first time here! :D Anyways, your pace is good and you are easy to listen.
I'm a professor at SDSU, perhaps you took one of my classes?
Wonderful stuff. A couple of questions: will you be doing any postgresql stuff and What's the distro you're using? Keep up the fanatic content!
Thanks. Sorry, I don't do much postgresql work. Currently using Pop!_OS as the distro on all my computers in the lab.
Great video... I'll test it ...!
Thank You so much for this good tutorial. I have a question about the Influence of Different DEMs on the cost path route. Did you use a different DEM than SRTM? DEM data such as ASTER GDEM, EU-DEM, etc. are they give different results?
You can use any DEM you'd like, but each source of the elevation data will have it's own inherent error. ASTER DEM's, for example, are created via stereo imagery rather than active remote sensing like the SRTM's, so they may have a wider range of error.
cool dear Isaac Ullah
is it possible to look at the codes so I can understand how you do this step by step

sir, the core method you used to extract features and model is SFM???? can you tell me?
Yes, SFM.
Helpful, Thanks
Well done
Thanks for clearing a lot of doubts through your video. I wanted to ask you how we can initiate missions without any additional software to achieve good coverage?
It's hard to do without a survey controller app. You would have to set up an automated flight in the native app using waypoints.
@@IsaacUllah_GIS_Tutorials I am experimenting with dronelink. Thanks
Could you please make a video demonstrating how to download a map with contour / elevation lines? Perhaps of this long / lat : 36.39651, -121.66098 . So little about this vast resource online yet. It will be appreciated by me and surely others as well.
Sorry, I cannot do that.
No worries. Thank you for replying at least. " )
Hi Sir, how can I download the data set when it theres an order scene option instead of the download option?
You have to order the scene and often pay a fee.
Another excellent tutorial Isaac!
Excellent video. Do you know any videos about how to use MeshLab to analyze drone textures specifically? Most of the tutorials of MeshLab do not work with drone imagery.
Not that I know of. There are some basic analysis tools in WebODM, however, which might suite your needs.
Do you know if it possible to import the output of meshlab into a QGIS 3D scene?
I don't use 3D in QGIS (just in GRASS), but you can export a mesh as GIS-readable format, such as DXF, csv, or LAS. As long as it is georeferenced it will read right in. If not, then you would have to rectify it with GCP's.
Thank You Sir. Very insightful. How can I get DEM data in adf file format please ?
I cannot answer that.
did you gsp's when taking the images
No GCP's, just the internal GPS to geotag the photos.
This is very cool Isaac
Thanks Ted!
THANKS .
This is a drone? Hoe to connect?
No, it is a lidar unit.
You are a legend! Very nice tutorial. Thank you!
It is not often I give feedback, but this really is a must see CZcams site, that if anyone has vague or serious interest in the capabilities of opensource drone mapping software then they need to check this site out.
Thanks Chris!
@@IsaacUllah_GIS_Tutorials Seriously I found the site extremely useful as I start my journey along the long path to getting a better understanding of what I can or cannot do with the drone, Thanks again, Chris
