Addressing unique labeling requirements with custom labeling workflows

Let's get started with a labeling job for our weather data. We want to label each weather report as good or bad. In order to help our workers do that, we'll make a nice frontend that shows the location of the weather station on a map and displays the reading from the weather station. We need a custom workflow because this scenario doesn't fall neatly into any of the existing Ground Truth templates.

We will have to set up the following:

• A private workforce backed by a Cognito user pool
• A manifest file that lists the items we want to label
• A custom Ground Truth labeling workflow, consisting of two Lambda functions and a UI template

The notebook LabelData.ipynb in the CH02 folder of our repository walks through these steps.
