 | Tag | Description     
 | +mkgmap:skipSizeFilter+  | If set to +true+ the line or polygon will pass the size filter, no matter what size it has    
 | +mkgmap:highest-resolution-only+  | If set to +true+ the object will only be added for the highest resolution configured in the element type definition.
+| +mkgmap:nooverview+  | If set to +true+ the object will not be included in the overview map.
 | +mkgmap:execute_finalize_rules+  | If set to +true+ mkgmap will execute the finalize rules even if no object is created fot the element.
 | +mkgmap:numbers+  | If set to +false+ for a node or way mkgmap will ignore the object in the calculations for the --housenumber option   
 | +mkgmap:drawLevel+  | Set to a number from 1 to 100. Overrides the polygon area that is used by --order-by-decreasing-area. 1..50 are larger than typical polygons and be overwritten by them, 51..100 are smaller and will show. Higher drawLevels will show over lower values.
