# 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](9.-applications).&#x20;

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

### 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
