Large download requests

Download limits

• In our download data tab in Digimap, we limit the amount of some map data products that can be downloaded in each request. The limit may be for a set number of National Grid tiles or for an area, e.g. 100km2. The limits vary between map data products.
• There is no limit to the number of individual requests for data that a user may submit.
• EDINA will contact any user who makes an unusually large number of requests for data to establish: whether the data are to be used for purposes permitted under the terms of the licence; whether there is an alternative, easier route for obtaining data.

Why are there limits?

Limits are in place to keep file sizes manageable and to reduce the processing load on our servers. This helps us complete your data requests more quickly and ensures fair access for all users.

Can I request a bulk download?

We understand that some educational projects may require larger datasets than can be obtained through standard downloads. If that is the case, you can:

Step 1:

Before contacting us, please watch this short video which explains how to reduce file sizes and manage your downloads more effectively:

Additional information on Step 1:

• If your request can be completed in fewer than 10 downloads, we will not consider it a bulk request.
• You may be able to reduce the number of downloads by selecting an area slightly within the tile boundaries rather than by tile name.
• We reserve the right to charge for offline bulk downloads that are particularly complex or time-consuming to manage.

Step 2:

If the data is still too large or you’re experiencing issues after watching the video, please contact our Helpdesk. with:

• The name of the data product you need
• An approximate area for the download

Our Helpdesk team can:

• Help you identify other sources of the same data
• Recommend alternative datasets
• Suggest more efficient ways to download the data, such as using national grid tile names or the reference grid overlay
