    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)

    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?

    Hi! Thanks for the explanation, it was very clear so I could apply it to my own work. I wanted to point out something though, when you reclassify the DEM from 2 - 10, you are assigning the value 10 to "flat areas", but isn't the DEM about topographic altitudes? Shouldn't you consider lower numbers as lower altitudes, and not as flat areas (isn't that why you have the slope there)? I say this because in my area, for example, I have the flat areas in higher altitudes (plains) and they can't get flooded even if they are flat, so I had to modify things a bit to get a more accurate end result (according to my area, of course). Anyways, thank you so much for explaining your process in such a detail way, it was really helpful!
