Retrieving a Radarsat-2 Product

EODMS Account

Before we begin working in SNAP, we first have to download a Radarsat-1 product from NRCAN. We begin at the Earth Observation Data Management System. A main screen as per Figure 1 should greet you. In order to download products, an account must first be created. This can be done by clicking on the Register (Required to Order) link under the Users subsection on the left-hand side of the page. Follow the on-screen instructions to create your account, confirm your email, and change your password.

If you already have an account, log into EODMS by clicking on the Login link under the Users subsection on the left-hand side of the page.

Retrieving a Scene

Once an account is created, we can begin searching for a scene. Begin by clicking the Search under the Getting Started subsection on the left-hand side.

The first step is to select our area of interest. This can be done is numerous ways, as indicated by the eight different drop-down menu's under step 1. For this example, Draw an Area will be used.
