Hi Alex, Looking at the rest of HeightField code in Destination.cpp I now believe to do the division properly we need a central function in Destination that we can pass the extents and get back the number of rows and columns required. This can then be used in the optimizeResolution() method and in the various places where a HeightField is created as a fallback for when no terrain data is provided as a source. Such an approach would ensure continuity between datasets where some areas have terrain sources, and others where there is none, through to datasets which have no terrain sources whatsoever.
