FIGURE 7-22 Complete gold model
16. Bring up the Gold Model again: Right-click the name in the Catalog Tree, pick Edit. Open the
Multiple Ring Buffer box for the oil wells. In the Distances area delete the 2500, with the little
cross under the plus icon, and put in 2286. Click OK. Fix up the distances for the tool dealing
with Wagt so they read 279 and 1834. Click OK.
17. Open the Select box and modify its SQL expression with the new distances. Run the model.
Print the Gold_Model from the Model menu. In ArcMap, print the final map for the client. Save
the map as Gold_Model_Map. Close ArcCatalog. Close ArcMap.
There is a lot more modeling capability than you have seen here. And more complexity. To learn more,
consult the ESRI manual Geoprocessing in ArcGIS .
Create a Python Script from the Gold Model
Another way to automate geoprocessing activities is with scripts. These are programming instructions in
languages that can be used to direct GIS processes. Writing scripts are beyond the scope of this topic,
but you should at least know of their existence and be able to execute one. You can use a model to make
a Python script.
18. Make a Python script of Gold_Model: Start ArcCatalog. Expand: ___ IGIS-Arc_ YourInitials >
Gold_Data > Toolbox.tbx > Gold_Model. Right click Gold_Model and choose Edit. Choose Model
> Export > To Python Script. In the Save As window, navigate to
