I am currently working on a project to create crop suitability maps using projected future climate data in the form of a NetCDF file.
The NetCDF (.CDF) files are for Temperature and Precipitation and are multidimensional with time slots and different variables like Max and Min. I also have the option of using a Cloud Raster File (.CRF) of the same dataset.
Hi HananAli!
Dealing with different kinds of data files can be challenging for people and machines.
Here's a help page with some useful information for processing netCDF files: https://pro.arcgis.com/en/pro-app/latest/help/data/multidimensional/a-quick-tour-of-netcdf-data.htm
This will help you on your journey. Keep us posted!
Thank you for your reply!
Is there anyway to hopefully change the projection of the NetCDF directly? I am attempting to find the most efficient way to work with the NetCDF layer directly for suitability analysis.
My process is very slow, I have to export each time frame as a raster layer, change the projection, then change the cell size. This has proven to be very time consuming. I need it to work in the weighted overlay tool, and it needs to match my other layers cell size and projection.
Thank you!
Hi HananAli!
I did another search for a solution to your problem and found one for changing the NetCDF file coordinate system at: https://pro.arcgis.com/en/pro-app/latest/help/mapping/layer-properties/voxel-layer-freqently-asked-q...
My NetCDF file has the wrong coordinate system. What should I do?
Place a projection file (.prj) with the same name as the NetCDF file in the same directory to override the coordinate system of the NetCDF file. See Save a coordinate system as a projection file to learn how to create a projection file.
Here's another page on Fundamentals of netCDF data storage: https://pro.arcgis.com/en/pro-app/latest/help/data/imagery/fundamentals-of-netcdf.htm . There is a section on Conventions you will want to take a look at.
Hopefully the above info will reduce at least one step in your workflow.
Since your workflow has a number of steps, have you considered using Model Builder to automate the process? It takes a little effort to get your model up and running, but once you do, it can be a thing of beauty.
