Demonstrating satellite imagery using AWS
In this demo, we will pull down a few bands from Sentinel imagery on AWS, merge them, and assign the bands to display true color in open source QGIS. We will use the AWS S3 CLI to copy the images locally for editing:
- To get started, install QGIS and the AWS CLI on either an Amazon workspace, an EC2 instance, or your local laptop. If you’re installing the AWS CLI on a workspace or a local laptop, you will also need to generate an IAM user and run the
