This chapter gives you background about Data Lens and what you need to know to get started with this Tutorial.
What is Data Lens?
What is this Tutorial About?
The example plots earthquake events on a map of the world. The events are represented on the map with symbols, called "proportional markers", whose size, color, and opacity vary according to the magnitude and depth of each earthquake. The marker's size indicates the magnitude of the earthquake, and its color indicates the depth of the earthquake epicenter. We also define a relative opacity on the marker symbols to indicate the relative epicenter depth.
The steps you will follow in this tutorial are the following:
- Initialize the earthquake dataset in your Data Lens account.
- Create a query on the data using the Data Lens REST API query language.
- Publish the query to make it publicly available.
