Welcome!
My constant interest in building a learning community in classrooms led me to make RUclips videos to enhance the understanding of my students. The video tutorials in this channel are mainly created to provide online support for students in "GIS" and "Statistical Data Science" in Public Health from Beginner to Advanced levels and are not intended for monetary compensation. The video tutorials are designed in a logical order (from start to finish of the project), are easy to follow, and are particularly useful for visual learners. For more information regarding the content of the courses, please visit sites.google.com/view/healthgis
Thank you,

Nice work
Hello nice video, please i want to site this paper, how can I if it has been published.
Hello nice video i am interested in siting you work on flood risk analysis How do I site your paper if the flood risk analysis video have been published
How can I validate a model?
It is surprising me. You are a doctor.... Many thanks for you doc Abe Mollalo
Sir, can you give us some advice, where'd you get that floodrisk criterias & percentage of their influental factors as mentioned 10:49 ?
The best of all. Thank you
I really need your help brother. As my project is on estimation of Water Quality parameters in coastal waters using landsat 8 i want to measure chlorophyll a, and temp with it. Also i will be collecting filed data for these parameters from the study area so how can i point out each sample location just like you did for ticks please reply.
Does anyone know how I would do a very similar ANOVA but with data collected from 6 groups at 12 different timepoints? (i.e. plant height in 6 treatments; 3 plants per treatment, collected at 13 time points)
This tutorial saved my life. Bless you 🙏🙏
Thank you so much
The fill tool keeps returning error
Do you have a shape file for this sir ?
Thank you.
Clear and concise. No wast words.
i will surely appreciate if can give me one more tutorial based on vegetation condition index...thank you so much
that was an excellent explanations thank you for this tutorial. kindly consider putting one more on shapefiles, there was agap where you included the area of interest in the arcgis. thanks again
This helped me fix an issue I had. Thank you! I know I was doing something wrong stepwise
Glad it helped!
ترجمه باللغه العربيه
We don't have the shape file? Can you share this particular one?
Its in the description link to github.
When I used the eucledian tool, I did not get the same esult and the output was not in different classifications but instead in a colo scheme from lo wto high. Why?
very clear! great job, thanks
Great tutorial! Is the WorlClim website working? Because Ive tried to download the data, but the download does not went through.
Thanks its really helpful
Great explanation.
very clear! great job, thanks
Are there any sources that confirms the use of the specific percentages for the influential factors?
prity good sound!
Is there a link for your slope making in arcgis?
thank you very much
I am getting an error that the selected points are on non travseable points..kindly helpp
what are the value units for the precipitation data? Millimeters?
Good advice thank you
Shouldnt x be standardised when you input it into ks.test? Aren't you comparing your data to standard normal "pnorm"?
Helpful. thankyou so much
Hello, the research link you provided based on AHP, Table 5 there had values like 0.156, 0.118, 0.178 and so on form DEM, Slope, and Rainfall and so on. But here in your slide, its tiny bit different, is it because assumed just these 5 values and and found average yourself, or did you referred other books or papers?
This is a very productive video. Bless your effort!
Can you draw a normal curve without knowing the standard deviation, but know some x values?
I'm new to statistics and learning bunch of things for weeks, your video made a lot of sense to me. Thank you so much for the easier explanation, it was great with examples and some of it fitted my research data.
thanks for this
Do you have a tutorial for Arc Pro? Some of the settings don’t seem to be found in Arc Pro or perhaps renamed.
amazing !
How did you get the land cover and slope data?
how to select the road (line in polygon overlay) i have a criteria that the suitable location must be within the road i mean there is no buffer
also could you elaborate hw to get soul maps and it's classification
bro you made others seems like amateurs ..excellent work!
Wonderful presentation. Very useful and detailed. Kudos
Thank you for these tutorials, please continue if you have the time and resources.
