 <DD>All distance parameters (search, skip, flat distances) are supplied as meters instead of cells (default). To avoid situation when supplied distances is smaller than one cell program first check if supplied distance is longer than one cell in both NS and WE directions. For LatLong projection only NS distance checked, because in latitude angular unit comprise always bigger or equal distance than longitude one. If distance is supplied in cells, For all projections is recalculated into meters according formula: <code>number_of_cells*resolution_along_NS_direction</code>. It is important if geomorphons are calculate for large areas in LatLong projecton.</DD>
