Creating a color-coded map of pressure and velocity

Creating a color-coded map of pressure and velocity

Step-by-step guide

To help visualize steady state simulation results, create a color-coded thematic map based on attribute values. In this example, create a map of the pressure and velocity results.

  1. To open ArcGIS Pro, double-click the desired project .aprx file.
  2. Click the InfoWater Pro tab.
  3. In the Project panel, click Initialize.
    The ArcGIS ribbon, with the InfoWater Pro tab active, and in the Project panel, Initialize being selected and highlighted in red.
  4. On the ribbon, in the View panel, click Map Theme.
    The View panel, with Map Theme being selected and highlighted in red.
  5. In the Map Theme Identification popup, give the theme a name, such as “Steady_State, Velocity and Pressure Results”.
  6. Click OK.
    The Map Theme Identification popup with a name entered into the Map Theme ID text box, which is highlighted in red, and with OK being selected.

In the Map Theme dialog box, configure the map theme to display the needed information.

  1. Select Junction from the element type list.
  2. Click New to create a new junction sub-theme.
    The top-left corner of the Map Theme dialog, with Junction selected and New being clicked and highlighted in red.
  3. In the New Sub-Theme dialog, give the sub-theme a name, such as “Pressure”.
  4. Click OK.
    The New Sub-Theme dialog, with a name entered and OK being selected, both highlighted in red.
  5. In the Standard Sub-Theme window, Data Source group, set the Table drop-down to Output.
  6. Set the Field drop-down to Pressure (psi).
    The Standard Sub-Theme window, with the Table set to Output and Field set to Pressure (psi), both highlighted in red.
  7. On the Symbology tab, set Classes to 4.
  8. Click Set Break.
  9. In the table, change the settings as follows:
  • Row 1: Color Red, Size 7, Break 20.
  • Row 2: Color Blue, Size 5, Break 60.
  • Row 3: Color Green, Size 5, Break 120.
  • Row 4: Color Yellow, Size 7, Break 171.31.
  1. Click Save and Apply Sub-Theme.
    The Standard Sub-Theme window, with options configured for this example and highlighted in red, and Save and Apply Sub-Theme being selected and called out with a red arrow.

Now, create a new pipe sub-theme.

  1. Select Pipe for the element type.
  2. Click New.
    The Map Theme dialog, with Pipe selected for the element type, and New being selected and highlighted in red.
  3. In the New Sub-Theme dialog, give the sub-theme a name, such as “Velocity”.
  4. Click OK.
  5. Set the Table to Output, Field to Velocity (ft/s), and Classes to 3.
  6. Click Set Break.
  7. In the table, change the settings as follows:
  • Row 1: Color Yellow, Size 2, Break 0.5.
  • Row 2: Color Green, Size 1, Break 1.5.
  • Row 3: Color Red, Size 2, Break 10.
  1. Click Save and Apply Sub-Theme.
    In the Standard Sub-Theme window, settings appropriately applied and highlighted in red, and Save and Apply Sub-Theme being selected and highlighted in red.
  2. Close the Map Theme dialog.
  3. Zoom to the extents of the model.

The map shows the pressure and velocity displayed by these color-coded ranges.

The map, with color-coded ranges that show the pressure and velocity.

  1. Zoom into any areas that may require further review.
    The map zoomed in to a specific area of the system.

Realize that because this is based on a steady state analysis, this is just a snapshot in time for this system. It is also possible to create a thematic map based on a time varying output.

To reset the display to the default, as set in the Preferences:

  1. On the ribbon, View panel, click Reset Map Theme.
    In the View panel of the ribbon, Reset Map Theme being selected and called out with a red arrow.
