i have made a dataset which has values in my study region and rest of the area has NaN values. how do i remove the Nan values so that i get only my study area. i have done this to crop my study area. the current dimensions of the dataset is 450x4173x34, so after removing the NaN values the dimensions also should change. kindly let me know how to do this.
i tried using isnan but the output was in 1 dimension. i need my output in 3 dimensions.
