Introduction1:04
This is the introduction to the course. The course if broken down into 5 lectures.

Ingesting airphotos and performing block bundle adjustment9:06
Imagery used in the course can be downloaded for non-commercial, instructional use. The data is courtesy of First Base Solutions http://www.firstbasesolutions.com/
Mosaic Preparation5:33
In this lesson, we'll use Python to create an XML file that can be used by multiple people to edit the same mosaic. The multi-user mosaic editing tool ensures only one person is working on each part of the mosaic. You can therefore assign multiple quality assurance staff to make edits to the overall mosaic.

Mosaic Editing11:42
The mosaic editing tool is a great way to interactively make edits to the mosaic and see what the final result will look like when the full resolution mosaic is created. We will show you how to follow a logical editing process, which starts with setting the overall color balancing across the entire mosaic, making scene / scene level edits, and then drilling down to make dodging point level edits to smaller adjustements.

Generate full resolution mosaic5:15
Once you and your team are happy with the mosaic edits and that you have saved the changes in the mosaic editing tool, it's time to export the full resolution version of the mosaic. If you think more improvements are needed you can always go back to the mosaic editor, make additional changes in trouble areas, and re-run the mosaic export.
Touch ups to final mosaic3:29
Even after you have exported the final mosaic, you can use some tools in Focus such as the Smart GeoFill tool to make small adjustments to overexposed areas, or perhaps cloud patching (picking a image with no clouds of the same location and pasting it in to the final mosaic).

Requirements

Students should be familiar with air photo projects and the supporting information that is typically provided.
Students should understand basic photogrametric concepts such as the importance of ground control, tie points, cutlines and color balancing.

Description

This course offered by PCI Geomatics, using Geomatica Desktop Image Processing Software

Overview
Working with software to create ortho mosaics can provide flexibility and significant time savings. Many organizations choose to order imagery from a commercial vendor and perform the corrections to the data themselves.

Who is the intended audience?
If you are responsible for the production of ortho mosaics, or have an interest in creating ortho mosaics for your project or your organization, this course will teach you how to use Geomatica, which will provide all the tools you need to create highly accurate and perfectly color balanced mosaics.

What Materials will be used?
Students will be able to work with a licensed version of Geomatica as well as sample data sets to follow along with the instructor. Students are expected to install Geomatica on their computer and work with a copy of the data which will be provided.

How long will it take me to complete the course?
The course materials (videos) run for 35 minutes. You will likely play the videos several times and review certain steps. The expected time to complete the course is 2-3 hours.

Who this course is for:

Unless you have a role or interest in processing imagery, this course is probably not for you.
