Working with VHR data

VHR imagery has a lot of potential to be a powerful dataset for a range of polar scientific and operational use cases.

There are a number of particular considerations to be aware of when working with VHR data. This guides covers 10 key areas.

1. Satellite Operators

2. Image acquisition

3. Spatial resolution

4. Spatial accuracy and ortho-correction

5. Spectral resolution

6. Radiometric resolution and correction

7. MAXAR product options

8. Licensing and use restrictions

9. Applications

10. Future developments and things to look out for

What is VHR

Any optical imagery that is under 1 metre spatial resolution

Learning outcomes

• An overview of commercial VHR imagery satellite operators and data providers

• Examples of imagery product options typically available from commercial providers

• A foundational understanding of some key aspects of working with the data, including:

  • spatial and spectral resolution

  • dataset accuracy

  • pre-processing steps

• An understanding of where the data might be applied for science and operations in the polar regions
