+== Stop Dimension ==
+Users can control how many layers will be create by specifying a stop dimension. The stop dimension is set using the -s argument. If set to 64 then the builder will stop when height and width for current level are less than or equal to 64. If set to 1 then the builder will stop when height and width for current level are less than or equal to 1. Examples:
+
+Build overviews, specifying to stop when both width and height are less than or equal to 64:
+{{{
+ossim-img2rr -s 64 <your-file>
+}}}
+Build overviews, specifying to stop when both width and height are less than or equal to 32:
+{{{
+ossim-img2rr -s 32 <your-file>
+}}}
+
+Note a default can be set in the ossim preferences file, setting the keyword "overview_stop_dimension".
