Exercise Details
The FME Data Inspector

Locality

Melbourne, Australia

Data

Waste Collection (GeoJSON) Property Boundaries (ESRI Shapefile)

Overall Goal

Set up dataset display

Demonstrates

Use of Display Control and Background Maps in the Data Inspector

Start Workspace

None

End Workspace

None

In the previous exercise, we inspected some data from a translation and added a second dataset. Now we can rearrange the data to make the display clearer.

1

Start FME Data Inspector

Continue in the FME Data Inspector from the previous exercise. You should have both the converted Waste Collection data (as GeoJSON) and a dataset of property boundaries in Shapefile. The Display Control window looks like this:

2

Set Property Boundaries Symbology

Click the symbology icon for the PropertyBoundaries data in the Display Control window:

Set the colour for the property boundaries data (purple used in example):

Click OK to change the colour.

3

Set Waste Collection Symbology

It is somewhat difficult to tell where each of the waste collection boundaries currently. Let's rectify that.

Click the symbology icon for the WasteCollection data in the Display Control window.

Set the Pen Color to something that stands out (such as red) and set the pen width to 3:

Set the Opacity to 0 to make the area invisible. This will cause the data to just have an outline of each polygon.

Click OK to change the pen styling.

4

Add Background Map

When inspecting data it will help to have a background map to provide a sense of location. You can choose from many mapping services.

Toggle between the various mapping themes available in the Background Mapping drop down option in the toolbar:

A background map is added to the display. Notice that the data is reprojected to match the coordinate system of the chosen background. For example, the Stadia Maps background causes the data to reproject to Spherical Mercator, with a clear change of shape:

Once complete, the data in the inspector should be noticeably different and look something similar to the following:

This is just one example of updating the symbology to make your data more readable.

There is no one right answer when it comes to visualising your data. Make sure you play around with different colours, opacity and the draw order to see what works for you.

CONGRATULATIONS

By completing this exercise, you have learned how to:

  • Set symbology for inspected features

  • Set a background map for inspecting data
