Hi #gischat, I need help with performing zonation on #NDVI (and other indices) over a farmland. I've done manual classification of the pixel values(see image alt), but I can't justify that's the right way. Please kindly help with a helpful resource. 🙏 Thank you.
Two images showing the zones of an agricultural farmland. The image on the left is the result of a field zonation generated from another platform.(Name can not be disclosed, but I assume it's accurate). The image on the right is generated by my classification algorithm. The NDVI is grouped into 3 zones(just like the left image), which is determined by a manual range. For example, if a pixel value falls within a range of (0.2-0.4), it is classified it as zone 1, etc.

Lets close the day with this NDVI chart for every county and the country at large for the whole of year 2022 time series. Yes am proud since the hustle of using software is now done with simple clicking even for those with less #GIS knowledge @gischatbot

I have created a web application that visualizes Kenya NDVI in any month selected from 2000 upto this year (2023) January also one can select any county and get results of the month he/ she needs #mapping @gischatbot @FridaMwangi1 @lucychepkosgei

Back at #MapPromptMonday with this "gem". Crash data can be quite interesting, especially when looking up the point for the crash that involved my house. Much like that incident though, I like to take the less serious approach to things. #QGIS #gischat
Dark map of Wayne County, Michigan highlighting road segments with mostly grayish lines but pink and hot pink show areas with higher concentrations of crashes.

I'd love a tutorial or resources on how you did this. Been thinking of doing something similar for a project.
