Inspect a hydrant

In the previous lesson, you created a map to collect hydrant inspection information. In this lesson, you'll use Collector for ArcGIS to test how your map functions in the field by adding an inspection and a violation to a hydrant feature.

Download Collector for ArcGIS

First, you'll download Collector for ArcGIS as a free app on your smartphone or tablet. Collector allows you to remotely edit data in a shared map. Because it can be accessed from a mobile device, field workers can input the results of their on-site inspections directly into your GIS, eliminating pen and paper from the process.

  1. On your smartphone or tablet, find Collector for ArcGIS on Google Play or the Amazon Appstore (for Android devices), the App Store (for iPad and iPhone), or the Microsoft Store (for Windows 10 devices).

    Your experience may differ depending on whether you use the Android, iOS, or Windows version of Collector. The steps and images here are for Collector on an iPhone.

  2. Download and install the free app.

Open the map in Collector

Next, you'll open the Hydrant Inspections and Violations map in Collector.

  1. Open Collector for ArcGIS.
  2. If you aren't signed in, sign in to your ArcGIS organizational account.

    After you sign in, a list of your maps opens. If you have only a few maps, the Hydrant Inspections and Violations map may be easy to locate in the list. If you have many maps, it may be more difficult. In case the map is not easy to locate, you'll access the map through the Naperville Hydrant Inspectors group.

  3. Scroll to the bottom of the list of maps to see your groups.

    For Android users, tap the Menu button to view your groups.


  4. Tap Naperville Hydrant Inspectors.

    A list of maps in that group opens. Only the Hydrant Inspections and Violations map is in the group, so it is the only map listed.

  5. Tap the map to open it.

    If you have location services turned on, the map opens to your current location, regardless of the map content. You're probably not in Naperville, so you'll navigate there.

  6. Tap theSearch button.
  7. Type Naperville in the search bar and tap Search.

    Search results

    Naperville, Illinois, is the first search result.

  8. Tap the result for Naperville to zoom to the center of the city.

  9. In the panel at the bottom of the map, tap the close button to close the search results and tap Cancel in the search panel to close it.

Add an inspection to a hydrant

Now that you've opened your map and navigated to Naperville, you'll perform a mock inspection of a hydrant.

  1. Tap any hydrant on the map.

    The tapped hydrant is selected on the map. A panel opens, showing information about the hydrant.


    For Android users, tap a hydrant once to select it, then tap the pop-up to expand it.

  2. Scroll the panel to view more of the hydrant's details.

    Details of the hydrant

    The details include the information in the feature's attributes and actions you can take with the feature. Below the attribute information and before the actions is a section titled Related that includes inspections. For Android users, under the Inspections section, you will see options to View an inspection or to add a New inspection.

  3. Tap Inspections to view existing related inspection records or create new ones.


    The panel shows a button to add an inspection as well as a list of inspections related to the hydrant you've tapped. Since there aren't any inspections yet, none are listed.

  4. Tap Add.

    For Android users, under Inspections, tap New.

    The Inspections form opens. It contains the fields in the Inspections table. Swipe up to view the form full screen.

  5. Tap the Pressure (PSI) field.

    The field becomes editable.

  6. Enter a value of 60 (a standard PSI value for fire hydrants) and tap Next.
  7. Add data to the other fields. (You may have to scroll down to see some of the fields, including Inspection Date.)

    Completed inspection

    This is a test, so the values you add aren't important. Most fields require only a yes or no. When you add an inspection date, the title of the form changes to include it.

  8. Tap Submit to send the updates.

    For Android users, tap the checkmark button to save your inspection and return to the hydrant's details.

    You return to the map. The hydrant feature is still selected and the new inspection form is displayed.

    Inspection added to the hydrant

  9. Close the inspection form, and close the Inspections panel to see the hydrant's details again. Scroll down to the Related section and tap Inspections to view the inspections on the hydrant.

    For Android users, under Inspections, tap View.

    The inspection appears as part of a list, marked by its date. If you add more inspections, they will be organized chronologically.

Add a violation to your inspection

You published your hydrants layer to also include a table for violations observed during inspections. The Violations table does not have a direct relationship to the Hydrants layer, but it is indirectly related to it through the Inspections table. Next, you'll add a test violation to the hydrant.

  1. On the list of the hydrant's inspections, tap the inspection you just added.

    Recent inspection

    The inspection's form and available actions display in the panel. All of the values you inputted for the inspection are shown. Below the attribute information and before the actions is a section titled Related that includes violations. For Android users, the section is titled Violations.

  2. Tap Violations to view existing related violation records or create new ones.

    For Android users, under Violations, you can select View to see all existing records or select New to add a new record.


    The panel shows a button to add a violation as well as a list of violations related to the inspection you've tapped. Since there aren't any violations yet, none are listed.

  3. Tap Add.

    For Android users, tap New.

    A form containing the fields in the Violations table opens.

  4. Fill out the four fields (it doesn't matter what you enter).

    Violations form

  5. Tap Submit.

    For Android users, tap the checkmark button to submit the violation. Then, tap View to review the submission.

    You see the new violation as well as information about the inspection and hydrant to which it is related.

In these lessons, you converted a fire hydrant inspection process from a paper form to a digital one. First, you created a relationship class between a layer of fire hydrants in Naperville, Illinois, and an empty table with fields for inspection data. Then, you published the layer to ArcGIS Online or ArcGIS Enterprise and used it to create a web map. Finally, you opened the web map in Collector for ArcGIS and added a test inspection and violation. The inspection you added was automatically updated to the web map. You can access the data through both Collector and the original web map in your ArcGIS organization.

These lessons taught you about publishing data and using multiple applications in the ArcGIS platform to solve a problem. To learn more, try Mapping the Public Garden and Homeless in the Badlands.
