Spatio-temporal relationship is very important to spatio-temporal semantic expression in spatio-temporal data model and ittakes an significant part in the whole frame of spatio-temporal data model on the naval battlefield.Current expressions of spatial relation and temporal relation analyzed based on the feature of the naval battlefield, complete spatio-temporal relation-expressing on thenaval battlefield is established.On this foundation,the situation on which spatio-temporal relationship on the naval battlefield appliesis analyzed and the expression of spatio-temporal relation-operation is projected.
