A nearest neighbour approach might do what you want

Land use classes are categorical or dummy data type, an interpolation approach shouldn't be used with this kind of data. You can perform a resampling approach, but you'll lost in spatial resolution. This approach just will succeed if your no data pixels are small patches.

I have a raster that is based on a grid of 30 m resolution and in which each cell is assigned to one of ten land cover types (coded as 1, 2, 3, 4, ..., 10 in the raster). However, there are some NoData cells in the raster. Is there an efficient way to fill NoData cells with reasonable values of land cover types? Should I use an interpolation method?
