3. Geoprocessing When we perform geoprocessing tasks on our data, we are developing the components of a GIS model. We perform geoprocessing every time we: Use a tool interactively in ArcMap Use tools from ArcToolbox Execute commands using the command line Connect tools in ModelBuilder Use functions in a script (like Python)

5. Available land for development of a nursery

6. Siting of cell towers

7. Dynamic modeling is performed in a similar fashion, but has additional parameters requiring several iterations of the model.

8. Disease outbreak modeling

9. Real-time traffic analysis

11. The model can be coded into a GIS application, so that the steps are performed automatically.

12. Easier reproduction of results.

13. Simplification of workflow.

15. Workflow Efficiency There are many repetitive steps you will take in your daily workflow. Streamlining the process saves you time. If you always start working in a File Geodatabase with specific resolution and projection information, a model for generating your specialized GDB can be created.

16. Human Inefficiency You physically cannot perform the steps as fast as GIS can produce the results. Certain steps, such as iteration through a feature set would be prohibitively time consuming. You must perform the same steps 21 times to clip data to each individual NJ county. Rail use analysis: 200+ stations Minimize the amount of time spent “babysitting” GIS to perform complex analyses.

17. How do we model? ArcGIS has a drag-and-drop interface to ArcToolbox called ModelBuilder allowing you to develop a flow chart of your GIS workflow. This flowchart is then run step by step to perform your analysis. ArcGIS allows for custom scripting that can be added to ArcToolbox, introducing greater functionality. Custom export scripts, specialized versions of existing tools, develop tools not available in ArcToolbox.

18. ModelBuilder

19. Introduction to ModelBuilder Throughout your GIS education, you've performed several geoprocessing tasks We have used geoprocessing tools in sequence to analyze GIS data ArcGIS allows you to link tools together to create a workflow

20. Inside ArcToolbox

22. Creating a New Toolbox Creating your own Toolbox is not just for organizational purposes. It allows you to share your models with others. If you will be sharing your model and using relative addresses, you need to plan the folder location of your New Toolbox carefully. Default location for a New Toolbox created inside ArcToolbox is: C:serslt;user profile>pplication DataSRIrcToolboxy Toolboxes. Create a new Toolbox by right clicking in ArcCatalog and selecting New Toolbox.

23. How ModelBuilder Works Drag layers you want to participate into the model Drag tools you want to use into the model Output layers, tables, objects shown in green Connect the features using arrows Order matters to certain tools (Clip)

24. Determining Points Within Searching for a count by municipality of all the contaminated sites (KCSL) in Gloucester County Select just Gloucester County municipalities, then all KCSL within the selected area Then perform a spatial join on the two layers to find a count of KCS points within each of the municipalities
