# 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](https://guides.geospatial.bas.ac.uk/10-things-to-know-about-vhr-satellite-data/9.-applications). 

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](https://guides.geospatial.bas.ac.uk/10-things-to-know-about-vhr-satellite-data/1.-satellite-operators)
2. [Image acquisition](https://guides.geospatial.bas.ac.uk/10-things-to-know-about-vhr-satellite-data/2.-image-acquisition)
3. [Spatial resolution](https://guides.geospatial.bas.ac.uk/10-things-to-know-about-vhr-satellite-data/3.-spatial-resolution)
4. [Spatial accuracy and ortho-correction](https://guides.geospatial.bas.ac.uk/10-things-to-know-about-vhr-satellite-data/4.-spatial-accuracy-and-ortho-correction)
5. [Spectral resolution](https://guides.geospatial.bas.ac.uk/10-things-to-know-about-vhr-satellite-data/5.-spectral-resolution#relationship-between-spatial-and-spectral-resolution)

### 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
