This is the academic RU-vid channel for Dr. Isaac I. Ullah, associate professor of Anthropology at San Diego State University. Among other content, here I post GIS video tutorials for my classes at San Diego State University.

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.
Hello. Thanks for your interest. You can access the slides here: docs.google.com/presentation/d/1qASO9RqQF_90rQodVeNMLyA8hUHomzpe-Kk2XmuwWt4/edit?usp=drivesdk
@@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!
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.
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?
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 .
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.
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.
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?
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.
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.
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.

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?
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.
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.
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.
