Description
Deja, Here is the location and shape of the farm in Alberta for you to begin creating the shape file for acquiring the satellite data. I'll introduce you via email to the farmers so that you can double-check your boundaries with them.

My original plan was to use QGIS and find the NDVI the traditional way, but after learning about Sentinel hub, I figured that might be a quicker way to get it done. I attached graphs of the NDVI over the past year for all four spots we pin pointed. Going from here, what sort of deliverables do we want? Do we want to show NDVI over time as a graph? Show NDVI for a specific day? Explain what NDVI is? The pictures are rough drafts and can be cleaned up.

Interesting -- we see the obvious night-day and spring-summer-autumn-winter variation.
So I would suggest (for discussion prior to doing):
- For the four land sections download 5 years of data. This will avoid too much volume (e.g. 50 yrs) but give us enough to see consistent patterns.
- For each season (of each section) group the data into Spring / Summer / Autumn / Winter.
- Then calculate the average annual reading per season per 10m2
- Then animate these through time for visualization
- Then think about what see so far, and determined what next.

Hi!
- I downloaded 5 years of data for each of the plots except Wanerof. Can you please give me the coordinates? I forgot them. Also, the data downloaded for Marquardt is for the upper right hand side of the Homehalf plot. Please let me know if it's supposed to be the upper left half side. Each excel sheet has the mean overall NDVI for the plot and for each season. There is graph as well to visualize this. I tried doing the graphs in Plotly Chart Studio so they could be more animated, but I ran into rouble trying to visualize seperate columns for each season, hence why they are now in excel. This is something I need to work out....otherwise though, this is what I have for now.
Here again are the four land plots: https://caltopo.com/m/52KTS
Zoom in and right-click on the corners to obtain the exact coordinates. (Please advise if you are not provided that data -- I tested it in an alternate browser with success.)
For all four, please ensure you are working from these coordinates: apologies that I previously only sent this URL via email.
