This tutorial takes you step-by-step through the process of creating a model tool. In this kursus, the model built in the Executing tools in ModelBuilder tutorial is made into a useful tool by exposing komplet variables as model parameters.

For a broad overview of creating konseptual tools, see A quick tour of creating tools with ModelBuilder.

It is assumed that you have installed
ArcGIS for Desktop
(ArcGIS for Desktop Basic,
ArcGIS for Desktop Liwa, or
ArcGIS for Desktop Advanced) before you begin this tutorial. The data required for this tutorial (included on the
ArcGIS for Desktop
CD) by default is installed in
C:\arcgis\ArcTutor. The tutorial scenario is fictitious, and the original data has been adapted for the cak bimbingan.

To avoid corrupting the original data, copy the
ModelBuilder
folder from
C:\arcgis\ArcTutor
to the
C
drive on your computer. If you are copying the data to another drive or location, make sure to use that drive for all the steps below.

  1. Open the map document.
  2. Create the teoretis.
  3. Expose tool parameters.
  4. Create model parameters.
  5. Rename teladan elements.
  6. Set model parameter kiriman.
  7. Set konseptual penanda type.
  8. Set filters on eksemplar parameters.
  9. Set symbology for output data.
  10. Manage intermediate data.
  11. Change general komplet properties.
  12. Document the model.

1-Open the map document

Browse to the
C:\ModelBuilder
folder in Windows Explorer and double click the Extract Vegetation.mxd. This will berangkat ArcMap and open the map document, or

  1. Tiba ArcMap.
  2. On the
    ArcMap – Getting Started
    dialog box, click
    Existing Maps
    >
    Browse for more
    .

    The
    Open ArcMap Document
    dialog box appears.

  3. Browse to
    C:\ModelBuilder
    folder, select Extract Vegetation.mxd, and click
    Open.

    This opens the Extract Vegetation.mxd.

2-Creating the initial contoh

Follow the steps in Executing tools in ModelBuilder. The same model is used in this tutorial as the starting point.

Starting model

If the model was saved previously, open the contoh by right-clicking the model and selecting
Edit. If this model was saved after the model was run in the “Executing tools in ModelBuilder tutorial,” the model elements may have a drop shadow around them. To remove the runtuh shadows, validate the entire model by clicking the
Validate Entire Model
button
Validate Entire Model
on the ModelBuilder toolbar.

Double-click the example model from the
Catalog
window. The tool dialog box opens but shows no parameters, as illustrated below.

Model tool dialog

If you run the tool by clicking
OK, the model will run. The output of the model (ClippedFC) will
titinada
be added to the ArcMap table of contents, even though
Add To Display
was checked for the output variable. The reason is that when a model is run from its tool dialog box, the
Add To Display
setting is ignored. To add the output to the display, you must make the output variable a model indikator.

Another reason for creating teladan parameters is that you want to run the model with different inputs without having to open ModelBuilder every time, as illustrated below.

Model tool with all its parameters

Once the model parameters have been created, you can execute the model from its tool dialog box, supplying different values for the
Input Roads,
Buffer Distance,
Input Vegetation,
Output Clipped Feature Class, and
XY Tolerance
parameters. You don’t have to open ModelBuilder each time you want to run the acuan—you can use the tool dialog box instead. An added advantage of running a ideal from its tool dialog box is that a result in the
Results
window is created; running a model within ModelBuilder does not create a result in the
Results
window.

The remaining steps will expose eksemplar variables as parameters so they appear on the model tool dialog box as shown above.

3-Exposing tool parameters

To define the Buffer Distance and XY Tolerance parameters, you need to create transendental variables for them.

When you add a tool to a model, model variables are automatically created for input and output datasets, but titinada for any other tool parameters. The reason is aesthetics—if variables were automatically created for every tool penunjuk, the model diagram would quickly become unreadable. For example, when you add the
Buffer
tool to a model, a variable is automatically made for the
Output Feature Class
parameter. After you right-click
Buffer
and fill in the
Input Features
parameter, a model variable is created for the input features. All other parameters, such as
Distance,
Side Type, and
End Type, are not automatically added as variables in the model. The steps below create hipotetis variables for
Distance [value or field]
and
XY Tolerance.

  1. In the
    Catalog
    window, right-click the teladan and click
    Edit. This opens the paradigma in ModelBuilder.
  2. Right-click
    Buffer.
  3. Click
    Make Variable
    >
    From Parameter
    >
    Distance [value or field]
    .

    This adds the Distance parameter as a variable in the hipotetis.

    Exposing Distance parameter

  4. Right-click
    Clip.
  5. Click
    Make Variable
    >
    From Parameter
    >
    XY Tolerance
    .

4-Creating model parameters

Now that you’ve created variables for Distance and XY Tolerance, you’re ready to make model parameters.

  1. Right-click
    Distance [value or field]
    and check the
    Sempurna Parameter
    option, as illustrated below.

    Making model parameter

    The letter
    P
    appears beside the variable, indicating it is a abstrak parameter. This model parameter then also appears on the model tool dialog box.

  2. Create model parameters for the following variables (do titinada make a komplet parameter for
    BufferedFC):

    • PlanA_Roads
    • vegetype
    • XY Tolerance
    • ClippedFC

5-Renaming pola elements

ModelBuilder assigns default names to variables. Variable names are used for parameter names on the model tool dialog box. It is good practice to rename variables, especially if they are model parameters.

  1. Right-click
    PlanA_Roads
    and click
    Rename.
  2. Type
    Input Roads
    and click
    OK.

    The name of the variable changes to Input Roads.

  3. Rename the remaining variables as follows:
    • Rename
      Distance [value or field]
      to
      Buffer Distance.
    • Rename
      vegetype
      to
      Input Vegetation.
    • Rename
      ClippedFC
      to
      Output Clipped Feature Class.
  4. Save
    Save
    the kamil. You do not need to exit ModelBuilder.
  5. Double-click the pola from the
    Catalog
    window to open the pola tool dialog box. You may have to move or minimize the ModelBuilder window to access the
    Catalog
    window. The transendental tool dialog box should look similar to the illustration below. The kiriman of the parameters may be different on your dialog box, but this is not an issue since you’ll change the order below.

    Renamed variables

    You can execute your tool by clicking
    OK, but it is suggested that you choose a different output feature class before executing. The tool executes, and the output feature class is added to the ArcMap table of contents. Unlike running a model within ModelBuilder, running the model from its dialog box does not change the model diagram.

6-Setting paradigma parameter order

As illustrated above, the order of the parameters is not ideal. The standard practice is to order parameters as follows:

  • Required input datasets
  • Other required parameters that affect tool execution
  • Required output datasets
  • Optional parameters
  1. In ModelBuilder, click
    Model
    >
    Model Properties
    .
  2. Click the
    Parameters
    tab.
  3. Choose the
    Input Roads
    parameter and move it to the top using the Up and Down arrow buttons on the right side.
  4. Change the position of other parameters as shown below:
    Changing parameter order

7-Setting paradigma parameter type

Once the ideal parameters are set in the correct order, change the type of the parameter. If a parameter is a required penanda of a tool in the model, you will titinada be able to change the type to optional from these settings.

  1. In ModelBuilder, click
    Model
    >
    Model Properties
    .
  2. Click the
    Parameters
    tab.
  3. Click the cell under the
    Type
    category for
    XY Tolerance. A list appears with two options. For this example, keep
    XY Tolerance
    as an optional penunjuk and the rest as a required parameter type as shown in the illustration below.

    Changing parameter type

8-Setting filters on model parameters

You can restrict the type of input to any penanda by applying filters to parameters. The model in this example expects the
Input Roads
parameter to be line features. In the following steps, the penunjuk is modified by applying a filter so that it only accepts line features.

  1. Click
    Cermin
    >
    Transendental Properties
    .
  2. Click the
    Parameters
    tab.
  3. Choose
    Input Roads
    and click the cell under the
    Filter
    category.
  4. Choose the
    Feature Class
    filter.

    The
    Feature Class
    dialog box opens.

  5. Uncheck all the types except Polyline and click
    OK.
  6. Click
    OK
    on the

    Model Properties
    dialog box to apply the filter.

    Adding filter

9-Setting symbology for output data

The output of a sempurna can be set to have a particular symbology that is used to display the output. For this example, the symbology is based on the type of vegetation within the buffer zone. To set the symbology for the output data, the first step is to create a layer file, and the second step is to define the layer file in the output data properties. For this latihan, a layer symbology file has been created for you.

  1. In the ModelBuilder window, right-click
    Output Clipped Feature Class
    and click
    Properties.
  2. Click the
    Layer Symbology
    tab.
  3. Browse the layer file from the ToolData folder that you copied in
    C:\ModelBuilder\ToolData.
  4. Choose OutputSymbology.lyr and click
    Add.

    Setting output data symbology
  5. Click
    OK.

10-Managing intermediate data

When you run a model, output data is created for each process in the pola. Some of the data created is of no use after the model is run since it was only created to connect to another process that creates new output. Such data is called intermediate data. All outputs except the final output, or those that have been made contoh parameters, are automatically made intermediate data in the model. In this example, the output of the
Buffer
tool is only useful as an input to the
Clip
tool and is titinada used after that, so the Intermediate option is checked. You can choose to save the intermediate data by unchecking the Intermediate option.

Managing intermediate data

11-Changing general teladan properties

You can set the model name, label, and description for the model.

  1. Click
    Pola
    >
    Model Properties

    from the ModelBuilder interface.
  2. Type
    ExtractVegetationforProposedRoads
    for the name of the lengkap. No spaces are allowed in the model name.
  3. Type
    Extract Vegetation for Proposed Roads
    in the
    Tanda
    text box. Spaces are allowed in the lengkap label. This cap is used to display the teoretis name in the
    Catalog
    window.
  4. Type the desired text in the
    Description
    text box.

    Check the
    Store relative path names (instead of absolute paths)
    option so that you can share your model tool or move your pola data and teladan to a different location. This option is titinada used in this tutorial but has been introduced here as a good practice to follow for your future models and acuan tools that you will share.

    Learn more about the relative path option

  5. Click
    OK.

    Changing general properties

  6. Save
    Save
    the finished model and exit ModelBuilder.

    Complete model
  7. Double-click the model from the
    Catalog
    window to open the model tool dialog box. Since the model was saved with the predefined values, all the parameters on the dialog box are filled in. You can change the value of any parameter here by entering a new value. Click
    OK
    to run. The final output of the model (Output Clipped Feature Class) is added to the display by default, and the cermin messages are posted in the
    Results
    window. To see your results, uncheck the Vegetation Type layer in the map document table of contents.

    Final output

12-Documenting the pola

It is always a good practice to document the abstrak before you share it. To document:

  1. Right click the model in
    Catalog
    window and click
    Item Description.

    This opens the
    Item Description
    window, displaying the Description page.

  2. Click the
    Edit
    button on the
    Item Description
    window

    This opens the documentation penyunting to enter the item description.

  3. Type in appropriate description for each item in this transendental and click the
    Save
    button.

Additional analysis

If you want to do some analysis with the model, you can add the
Summary Statistics
tool to get a summary table of affected area by vegetation type within the buffer polygons around the proposed roads.

The steps below will also show you how to use a model as a tool inside another model.

  1. Open a new model by clicking the
    ModelBuilder
    button
    ModelBuilder
    on the ArcMap
    Standard
    toolbar.
  2. Now that you have created a model tool, you can use it just like any other tool. You can add the model tool to a new konseptual by dragging it from the
    Catalog
    window into the new model, as illustrated below.

    Adding model within a model
  3. Since the konseptual tool had predefined values for input and output parameters, it is added to the new model with input and output variables (the blue and green ovals). Note that not all parameters of the model tool are exposed when added in another contoh. Also, the original names of the input datasets have been used. You can make variables and rename them as described earlier in this tutorial.

  4. Open the
    Search
    window (if not already open in ArcMap) by clicking
    Geoprocessing
    >
    Search For Tools
    .

    This opens the
    Search
    window.

  5. In the
    Search
    window, type
    Summary Statistics
    and click the
    Search
    button
    Search.
  6. Drag the tool into the hipotetis.
  7. Double-click the Summary Statistics element to open the tool dialog box.
  8. For the
    Input Table
    parameter, click the arrow and choose
    Output Clipped Feature Class
    with a blue recycle icon
    Model Variable
    next to it. This recycle icon means it is a variable in the model.
  9. For the
    Output Table
    parameter, browse to the output geodatabase (C:\ModelBuilder\Scratch\Output.gdb), type
    AffectedVegetation
    for the name, then click
    Save.
  10. For the
    Statistic Field(s)
    indeks, choose
    Shape_Area
    from the list.
  11. Click the cell next to
    Shape_Area
    under
    Statistic Type
    and choose
    SUM
    from the drop down list.
  12. For the
    Case field
    parameter, choose
    VEG_TYPE
    from the list.
  13. The completed kamil with the
    Summary Statistics
    dialog box is illustrated below.

    Adding model within a model

  14. Click
    OK.
  15. Right-click
    Output Clipped Feature Class (the green bujur telur)
    and check
    Add to Display. This adds the output to the display after the model runs.
  16. Right click and check the
    Add to Display
    option for the
    AffectedVegetation
    variable. This will add the ouput to the display after the model runs.
  17. Run the model.

    The output
    Output Clipped Feature Class
    and the
    AffectedVegetation
    table are added to the display in the ArcMap table of contents.

  18. Open the table by right-clicking and clicking
    Open.

    The table shows a summary of area by vegetation type within the buffer polygons that will be affected by the proposed roads for plan A.
