# Downloading OS OpenData

Firstly, OS VectorMap District needs to be downloaded from the OS Data hub:

{% embed url="<https://osdatahub.os.uk/data/downloads/open>" %}

Scroll to **OS VectorMap District**. Ensure that the data type is raster, and select grid reference square using the two letter reference list. Southampton lies in the **SU** grid reference square, so **SU** has been selected from the reference list.

## **Downloading OS OpenData**

* Tick the box for Download (as seen in download page image).
* Scroll down to the bottom of the page and click **Next**.
* Fill in the details required and you will receive an email with a link to download the data as a .zip file. Save to a designated folder. Once the download is complete extract the file.

Now you will have a folder containing 100 TIFF image files (.tif) from SU00-SU99, which are 10km x 10km tiles that are numbered to their relative position in the grid:
