Creating a bandpass filter for data varying in space (x,y) and time (t)

I have spatial data (x,y) that is sampled every day for a year (t) and I want to try to develop a 30 - 60 day bandpass filter for the data. I've tried using the filter toolbox with the settings listed below:

Response Type - Bandpass Design Method - Butterworth Filter Order - 10 Frequency Specs Units - Hz Fs - 365 Fc1 - 30 Fc2 - 60

I have reshaped the x,y data to (t,x) where each x point represents each spatial location (x,y) and each t an observation. Each (:,x) is a time series at the given location

I have not worked with filters too much and I would like to hear some suggestions and see if I am on the right track.

Thanks
