If you feel like using ArcGIS Of Model Builder It can not meet your customized processing flow , Consider the following use ArcGIS In the middle of python hold-all . Through it, you can python The form of the code , call ArcGIS Things in the toolbox , That is to say ArcPy, It is very convenient for special application scenarios . Developers can put their own logic , Encapsulated as a tool , Directly provide other computers to install ArcGIS The personnel who use .
establish Python hold-all
stay ArcCatalog in My toolbox Right click , choice newly build ——python hold-all
Right click the created toolbox , choice edit , In the pop-up edit box , You can write code by typing
