2. What is ModelBuilder?
What is a Model Builder?
is an application in which you can create, edit, and
modify models!
“Model” is an ideal representation()
(Ex. Role model)
“Builder” building an ideal representation
Why we need Model Builder?
reduce the ambiguity and redundancy
to increase one’s efficiency;
Optimization
Visual Programming!
3. Why Model Builder
• Developing a model for a GIS analysis allows for
repeat testing of a hypothesis using different
data.
• The model can be coded into a GIS application, so
that the steps are performed automatically.
• Easier reproduction of results.
• Simplification of workflow.
• Informs the computer how to conduct a series of
steps that would be impractical for you to do
manually.(TT process)
4. 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)
5. Human inefficiency
• Physically cannot perform the steps as
fast as Model Builder can produce the
results.
• Certain steps, such as iteration through a
feature set would be prohibitively time
consuming.
(perform the same steps)
• Minimize the amount of time spent
6. Efficient Workflow
There are many repetitive steps you will take
in your daily workflow.
Streamlining the process saves you time.
7. Types of Model builders
Executing tools Model Builder
often used method
Simple & easy
Creating tools with Model Builder
Use of Elements, connectors and
8. Additional Functionality
• The Model can be
expanded further, with
more data and tools(Edit
option).
• The Model can be
exported into a scripting
language, allowing for
greater modeling
capabilities.
• Python is the default (and
recommended) scripting
language for ModelBuilder
9. 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 Create
a new Toolbox by right clicking in ArcCatalog and
selecting New Toolbox.
