Asking for help, clarification, or responding to other answers. A negative distance shrinks the geometry rather than expanding it. For geography this may not behave as expected if object is sufficiently large that it falls between two UTM zones or crosses the dateline. You will have to transform to some metric projection to use the buffer setting you are expecting. I remember needing this to get geometries that would play nice with ArcGIS's geometry validation rules -- that has always been a bit of a dark art in my experience as things that are valid in GEOS or other tools like PostGIS or the Java Topology Suite can still be invalid in Arc. For example, it does not What are the main differences between R data files? A positive buffer distance will expand the polygon outward, while a .
