This past week we learned a lot of validation tools such as Keepright,Josm inspector and josm validator.these have proven effective at identifying and fix a lot of errors that have been found in the editing of maps in the previous challenges.I would therefore advise fellow mappers to use these tools in fixings the errors commonly found in the maps.For clarification of such tools and how to use them,please contact,stan,nuts,seisa,lekoro,t’sepo and dave.
