I am wanting to calculate the average trend in maximum annual NDVI in Iceland from 2010-2020 using MODIS MYD13Q1 V6. How would I do this?
I have currently inserted the NDVI bands from the MODIS (which I downloaded from the earth explorer website) into ArcMap for each year and used the cell statistics tool to calculate the maximum NDVI and used the raster calculator to remove any negative values, leaving me with maximum NDVI layers for 2010 through to 2020 but I do not know how to calculate the average trend for this period.
Please can someone advise me on how to do this and also any statistical analysis I could use - I am familiar with R so preferably using RStudio to do this statistical analysis, thanks!
