returns the xy tolerance of the spatial reference . the tolerance value defines the precision of topological operations , and `` thickness '' of boundaries of geometries for relational operations . when two points have xy coordinates closer than the tolerance value , they are considered equal . as well as when a point is within tolerance from the line , the point is assumed to be on the line . during topological operations the tolerance is increased by a factor of about 1.41 and any two points within that distance are snapped together . concode_field_sep long serialVersionUID concode_field_sep int getOldID concode_elem_sep int getLatestID concode_elem_sep String getText concode_elem_sep SpatialReference create concode_elem_sep SpatialReference create concode_elem_sep SpatialReference fromJson concode_elem_sep SpatialReference fromJson concode_elem_sep int getID concode_elem_sep String toString concode_elem_sep Object writeReplace concode_elem_sep boolean isLocal
