Feature Manipulate Engineering

Read Web Data

Define a transformer.
Make HTTP calls using the HTTPCaller transformer.
Turn a JSON response into features using the JSONFlattener transformer.

A transformer is an FME Workbench object that carries out feature restructuring. Schema (sometimes known as “data model”) can be described as the structure of a dataset, or, more accurately, a formal definition of a dataset’s structure.

For Microsoft Excel data being read by FME Workbench, a feature type is:

A Microsoft Excel XLS or XLSX file
A sheet in the Microsoft Excel file
A row in the sheet
A column in the sheet

The Coordinate System parameter for the Microsoft Excel reader should be set if:

The data will be viewed with a background map
The data will be compared to other data in a different coordinate system
The writer format requires a coordinate system
All of the above

How many rows of data are in the BusinessOwners feature type?

While you create an FME workspace for your own use, you are an:

Author
End-user
FME Flow Developer
Administrator

In the Translation Log window, ERROR entries will be colored:

Black
Blue
Green
Red

The error in Sven’s workspace was caused by:

FME being unable to convert Microsoft Excel data to an Esri file geodatabase.
Not connecting the correct feature types.
Not setting the Geometry parameter on the writer feature type.
Connecting features with incompatible geometry types to the writer feature type.

The Feature Type dialog box can be opened by:

Double-clicking on the feature type on the canvas
Clicking on the cog-wheel button on the feature type on the canvas
Right-clicking on the feature type on the canvas and selecting “Properties” in the drop-down menu
All of the above

Once you add writer feature types, you are free to connect them or delete them as you wish.

True
False

The name of a feature type always sets the name of the output file.

True
False

Navigating to the location of your written data requires remembering your file path and manually finding it using your operating system’s file browser.

True
False

What is the size of the written geodatabase to the nearest KB? Choose the closest answer, as results will vary slightly.

171
498
836
2,932

After clicking on a port, holding down the CTRL key (⌘ or Shift on Mac) allows you to connect a feature connection to multiple ports.

How many points are in the point cloud?

1,054,031
491,384
5,458,240
11,527,736

What is the unit of the coordinate system used by the LAS file?

Meters
Feet
Decimal Degrees

Feature Information shows:

User defined attributes
Format attributes
List attributes
All of the above

The 3D view in the Graphics View can be rotated using the:

Zoom Extents tool
Zoom In tool
Pan tool
Orbit tool

A template can contain:

A workspace
Source datasets
Caches
All of the above

Background maps, if selected, will display in both 2D and 3D views

True
False

What is the definition of a transformer?

An object in a translation that carries out feature restructuring.
An object in a translation that describes an identifiable subset of records within a dataset.
An object in a translation that writes to a destination dataset.
An object in a translation that reads a source dataset.

Which transformer is most commonly used for making API calls?

Creator
HTTPCaller
JSONExtractor
JSONFragmenter

When using the JSONFragmenter, what happens if you enable Flatten Query Result into Attributes but do not provide attribute names in the Attributes to Expose parameter?

Performance will be negatively impacted
The JSONFragmenter will output rejected features
The translation will fail
Any flattened attributes will be unexposed

Why do the points from the VertexCreator not appear in the correct place on the Visual Preview Graphics view?

The Graphics view is not configured to show points
The VertexCreator is not the correct transformer for creating points
They do not have a coordinate system set
You have to manually move them by selecting them in Visual Preview and dragging them to the correct location.

Your data appears to be in the incorrect place in the Graphics view, and the Feature Information Window reports the Coordinate System is Unknown. Which transformer do you need to use to fix this problem?

CoordinateSystemExtractor
CoordinateSystemRemover
CoordinateSystemSetter
Reprojector

Which of the following does not indicate your data is missing a coordinate system?

The Feature Information Window reports that the features’ Geometry > Coordinate System is set to Unknown.
The Graphics view has a warning ribbon that says, “Some features in [port] may not align with the background map.”
The features do not appear where you expect.
The Graphics view reports the data uses “Unknown Units” in the bottom right.
FME Workbench crashes when you try to inspect the data.

One stream of features in your workspace uses the UTM83-10 coordinate system. Another stream uses BCALB-83. You would like to find where they intersect using the Intersector transformer. Which transformer do you need to use to ensure the datasets align properly before intersecting them?

CoordinateSystemExtractor
CoordinateSystemRemover
CoordinateSystemSetter
Reprojector

Where can you view the schema of your source data, i.e. the data you start with?

The Transformer Gallery
The writer entry in the Navigator
The reader feature type dialog
The writer feature type dialog

Opening the writer feature type dialog and adding a new attribute is a form of:

Schema mapping
Schema editing
Structure componentizing
Data refreshing

Which of the following operations is not possible using the AttributeManager?

What Attribute Definition mode would you use on a writer feature type if you wanted the schema to change to match incoming features?

Automatic
Manual

You just made a change to a transformer in the middle of your workspace and want to rewrite the output data to reflect the change. Which partial run button would you use after clicking on the transformer where you made changes?

Run To This
Run From This
Run Just This
Run Between Selected

To inspect a feature cache in Visual Preview, click the:

Green magnifying glass icon
Transformer cogwheel icon
Run button
Canvas

Partial runs can help speed up the authoring of workspaces by:

Allowing you to only run part of your workspace.
Allowing you to update a single cache.
Allowing you to quickly inspect data you just added to the canvas.
Allowing you to create a cache of web, database, or compressed data.
All of the above.

You have a Tester reading road features. There are two tests: the first tests if the road type is a highway, the second tests if the road type is an off-ramp. Which Logic option do you need for the Tester to pass both highways and off-ramps features?

AND
OR
AND NOT
OR NOT

All FME workspaces must have multiple streams of data.

True
False

What happens when Automatic Inspect on Selection is enabled, and you click a transformer with multiple feature caches?

All feature caches are inspected
No feature caches are inspected
The top cache only is inspected
The bottom cache only is inspected

Which setting must be enabled to ask the user to optionally set a value for a user parameter at run time?

Published
Required
Disable Attribute Assignment
Conditional Visibility

FME Flow can run workspaces on a schedule.

True
False

User parameters let FME users:

Control how workspaces run

If Fatima changes her mind and wants a weekly update instead of a monthly one, where does Frank need to go in the Automation to make the change?

Email External Action > Email To parameter
Run a workspace Action > Output Keys
Schedule Trigger > Start parameter
Schedule Trigger > Recurrence parameter
None of the above

Which of the following workflows could be created using Automations?

When an AutoCAD DWG file is uploaded to an Amazon S3 bucket, run it through a quality assurance testing workspace. If it passes, convert it to a GIS format and upload that to S3. If it fails, email the uploader.
Automatically run a nightly database backup.
When a field technician emails in a daily summary spreadsheet via email, email them back a report with a route map and weather forecast for their sites the next day.
When a user adds an Excel file of addresses to a Dropbox folder, automatically add another file with all the addresses geocoded.
All of the above

Which of the following scenarios would benefit from the use of an Automation running on a schedule?

Automatically updating a database every time a file is added to an S3 bucket.
Automatically providing a dataset whenever an email is received with a particular subject line.
Automatically making an API call to an asset management system whenever a GIS layer is updated.
