Get One Feature Attribute

I am following the Get Feature Attributes sample workflow that uses the Get Workflow Input activity at the beginning.

While I can get the entire list of attributes for the selected feature, I can't figure out how to get only the OBJECTID into a value, so I can use it as part of a query.

Any help is appreciated.

  Hi Michael,

  I do not know about the workflow you mention, so if you are able to share it with us, I would be happy to help.

  In the meantime, some useful information about working with VertiGIS features. As you have normally retrieved these from a VSW operation, you should note the following things:

  Iteration

  The VertiGIS Features can be iterated using JS Array Operations like forEach(), map() or find()

  Example: Find the Feature with OID = 321

  • $runOperation1.result.find(feature => feature.attributes.get('OID') === 321)
  • Result will be the VertiGIS Feature 

  Example: Retrieve a list of all OIDs for all features

  • $runOperation1.result.map(feature => feature.attributes.get('OID'))
  • Result will be a list of OIDs --> [1,2,4,9]

  Get Values

  Once a VertiGIS Feature is retrieved, the values can be accessed using get()

  Example:

  • $runOperation1.result.feature.attributes.get('my-attribute')

  Set Values

  And they can be updated using set()

  Example:

  • $runOperation1.result.feature.attributes.set('my-attribute', 'my new value')
