Hi Thanks a lot for replying. I checked geometry and it returned a empty table, so I assume the geometry has no problem. The Asia_dissolve.shp I used for dissolve has unique value in attribulte "COUNTRY". The dissolve step ran successfully. But in order to get individual country.shp from Asia_dissolve.shp, I used SPLIT function. The "empty geometry" error happened in this step. Any idea or any other function rather than SPLIT allows me to get individual country.shp? Thanks. Hi, 1, please use 'check geometry' to see the problems and fix it by using repair geometry. if you are using for first time, please backup your data. 2, you cannot dissolve based on country. make sure you make new attribute 'continent' and fill asia for all asian countries. then dissolve it. dissolve tool works by merging all features that have 'same' value of attribute in the selected field.
