Viewing satellite imagery in FocusViewing your imagery in its native format is the first step in Focus. We will use Focus within Geomatica to view our satellite imagery in its native distribution format, and view the different possible methods to opening imagery in Focus. Additionally, we will examine the different distribution formats you might encounter with satellite imagery.

Imagery and the PCI data Format
To better view your images and their contents, we need to import each one of our images to the PCIDSK format. By importing our images to the PCIDSK format, we optimize the viewing of the imagery and centralize all the different files related to an image into a single file for easy handling. The benefits of using the PCIDSK format and how to import to the PCIDSK format are described in this lecture.

Managing your images in Focus
There are a number of different arrangements of image bands that can be applied to produce natural and false composite RGB images. These different image compositions can be used to highlight features of interest in the landscape. In this lecture, we'll examine the different image management components in Focus and how to configure and view RGB images.
How long do I have access to the course materials?
You can view and review the lecture materials indefinitely, like an on-demand channel.
Can I take my courses with me wherever I go?
Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don't have an internet connection, some instructors also let their students download course lectures. That's up to the instructor though, so make sure you get on their good side!
