Batch Merging Method of Vector Layers with the Same Name based on GIS Model Builder
To solve the problems of low efficiency and omission in conventional vector layer merging methods,ArcGIS model builder is used to create vector layer merging models with the same name based on three iterators:iterators-feature classes,iterators-field values,and itera-tors-row selection,achieving batch and accurate vector layer merging.The key tools are introduced,and the idea and flow chart of model creation are described.The results indicate that the merging of specified layers can be efficiently accomplished using any batch merging tool,with comparable and high efficiency.The merging of all layers with the same name using the"iterators-row selection"method is the most ef-ficient,which is 32.7%more efficient than the"iterative feature class"method and 21.9%more efficient than the"iterative field value"method.The iterators-row selection method can,to some extent,replace the iterators-field values method.The created model is convenient for transplantation and sharing.
