Getting started with temporal filtering
Introducing temporal filtering
Temporal filtering allows you to order a one-off snapshot of data from the OS National Geographic Database (OS NGD) from a current or past date.
Temporal filtering is an optional step when you create a new data package against one of your existing recipes. For further information and step-by-step instructions on creating recipes and data packages, please see the 'Downloading with OS Select+Build' page.
How do I add a temporal filter to a new data package?
To create a new OS NGD data package and apply a temporal filter to it:
Log into your OS Data Hub account.
Select the desired coordinate reference system
Select a file format: CSV or GeoPackage
Select the updates you want
Instead of selecting the 'not required' or COU (Change-Only Update) frequency options (which are available under the 'Select updates' drop-down), to apply a temporal filter, you should select the option for a one-off snapshot of a current or past date by ticking the following check box:
You will receive an email confirming that your data package is being created and another one when your new data package is ready to download.
