Description: Suppose you have a single-layer floating point data with small holes (zero values) randomly scattered throughout (such as terrain data derived from interferometric SAR or LiDAR techniques). The goal of this Model is to replace all of the pixels that have a value of 0.0 with the mean of the surrounding eight pixels, but if any of the eight surrounding pixels have a value of zero, they will be excluded from the mean calculation. All of the non-zero pixels in the image are to remain unchanged.
