Dear Vasala Saicharan,

You can do it using ArcGIS. Please follow the attached link I think it will help you.

Dear Pritiranjan Das ,

Thank you for the response.

But, I want to make a map of correlation for a particular region not in the graph format.

Like the attached file,

Hi! Neat issue. My approach in R would go like this:

Create a fishnet grid of the region with the appropriate size of cells (eg. 10 m, 100 m, 1000 m, etc.). Preferably in the sf package in R.

Extract the raster data for your first raster and average it into the fishnet grid. Repeat for the second raster you want to correlate.

Do you have some geographic boundaries that you want to use to split up the regions in your raster? Eg. If you have a rainfall dataset and a sunlight dataset for the entire US, do you want correlations for each US state? If so, you can use st_join function to merge in a vector of state names for each fishnet cell.

Last, you can use group_by() and summarize() with the cor() function to get the correlation between the two rasters.

I'll go grab some specific code examples.

Dear Timothy Fraser,

Thank you for your response. Can you share a specific code example?

Certainly; I wrote up the code this morning. Best of luck! https://www.timothyfraser.com/tutorials-in-r/mapping-raster-data-in-the-tidyverse

Dear Timothy Fraser ,

Thank you so much for your swift response and spending your time in providing a detailed procedure. I will follow the tutorial steps.

Thank you.

You have to use any programming language for the correlation map in the spatial form (pixel by pixel). I prefer to use python for the same.

You can refer to my recent publication on time series analysis where I prepare the pixel by pixel trend analysis map (spatially) of 18 years data.

Dear Pir Mohammad ,

Thank you for your suggestions. I glanced at your paper, it was informative.

Is it possible to share your code repository?

Thank you.
