Let's continue your work on the fundraising walk project.

In case you forgot, the city is hosting a fundraising walk for a major charity and you have been tasked with using FME to put together the data that will form the event map.

In this part of the project we’ll add another of the source datasets to the workspace as a reader. This format will need close inspection of the reader parameters to make sure we're reading the data correctly.

1) Start Workbench
Start Workbench (if necessary) and open the workspace from Exercise 1. Alternatively you can open C:\FMEData2017\Workspaces\DesktopBasic\Components-Ex2-Begin.fmw

2) Add Reader
The existing workspace already has a Reader for MapInfo (parks) data. Now let's add one for the most important dataset - the walk trail. This was walked by a colleague and captured on his GPS device.

Select Readers > Add Reader from the menubar in Workbench. When prompted fill in the following details (but don't press OK):

The coordinate system setting is below the Dataset parameter, on the right hand side of the dialog. It's important to specify the coordinate system here because we're going to be dealing with lots of datasets with different coordinate systems, and data unflagged with coordinate system information is going to be problematic.

Now press the Parameters button. This brings up a parameters dialog that is rather large and looks like this:

The dialog includes various parameters for this reader and a preview of what the source dataset looks like. By default the Delimiter Character should be a comma (change it to a comma if it is not) and the Field Names Line parameter should be set to 1.

In the lower part of the dialog - under Attribute Definition - click the button marked Manual. Now change the type of the Latitude attribute to a y_coordinate and the Longitude attribute to an x_coordinate:

By setting these parameters FME will convert the plain-text CSV data into true spatial features. Click OK to close this dialog and OK again to close the Add Reader dialog.

3) Check Reader Parameters
Locate the CSV reader in the Navigator window and expand the list of parameters to see what there is:

Notice that some of the parameters we set earlier are no longer available. That's because they specified how to define the feature type schema, and it's too late to set them now.

There are other parameters, but none we need to set for this exercise.

4) Add Reprojector
The one issue with the CSV data is that it is in a Latitude/Longitude coordinate system, and not the same UTM system as used by the parks data. Let's fix that by adding a Reprojector transformer to the workspace.

Connect it to the CSV reader feature type and set its parameters to reproject from Read from feature to UTM83-10:

Also, as in the above image, connect the Tester:Passed output port to the Reprojector.

5) Run Workspace
Feel free to add Inspector transformers and run the workspace to inspect what we have created so far.
