Frequently Asked Questions

The frequently asked questions are separated in to two sections, one for the Land Cover data from CEH and the other for the Dudley Stamp Land Utilisation Survey data:

 

CEH Land Cover data FAQ

1. Can I compare the land use datasets over time?

Owing to improvements in satellite mapping technology and data collection methods, comparisons of the 1990, 2000 and 2007 datasets to detect change over time must be treated with caution. Many changes appear because of the improvements in the methodologies used to create the data and do not necessarily reflect actual change on the ground.

2. Can I use this data in a publication?

You may use these data as part of publications according to the stipulations given in Section 3.1 of the End User licence Agreement. You are responsible for checking the whether or not you are permitted to use the data in any specific publication or type of publication, including section 4.1 regarding the restrictions on what you can do with the data.  But, broadly speaking, you may publish maps showing the CEH data in academic journals or on websites.  You should also check the End User Licence Agreement specifically for the acknowledgements which must accompany any publication.

3. Can I use this data in a public facing website?

Clause 3.1.11 of the End User Licence Agreement says that you may publish maps of the data on the website of your Authorised Institution or websites created as part of a course or project.

4. Can I use this data in teaching exercises?

Clause 3.1.5 of the End User Licence Agreement says that you may, for Educational Purposes only, incorporate parts of the Licensed Work in printed and non-manipulable (e.g. locked .PDF file) electronic course packs, study packs and course notes hosted on a Secure Network, virtual learning environments, managed learning environments and multi-media works.  It is your responsibility to ensure that each item carries the appropriate copyright notice and/or acknowledgements as listed in Appendix 1b of the End User Licence Agreement. Course packs in non-electronic non-print perceptible form, such as Braille, may also be offered to Authorised Users.

5. Can make print outs of the data for posters or hand-outs?

Yes. See clauses 3.1.8 and 3.1.10 of the End User Licence Agreement.

6. Am I permitted to archive my research, including the data I downloaded from this service, in an online repository?

Yes. Clause 3.1.6 of the End User Licence Agreement says that you may incorporate parts of the Licensed Work, in printed or electronic form in assignments and portfolios, theses and in dissertations and to make reproductions of the Academic Works for personal use and library deposit.  If your Authorised Institution’s library has an online repository, you may deposit your research here.  Note that this is still subject to the restrictions given in Clause 4.1 of the End User Licence Agreement, which you should check.

7. Am I permitted to download and present this data in presentations using PowerPoint?

Yes. Clause 3.1.8 of the End User Licence Agreement permits you to publicly display or publicly perform parts of the Licensed Work as part of a presentation at a seminar, conference, or workshop, or other such similar activity.

8. How long am I allowed to keep this data on my computer and/or server?

You may only keep electronic copies of the data for as long as you remain an Authorised User.  Should you leave your institution or otherwise cease to meet the criteria given in the definition of Authorised User, you must delete any data you have downloaded.  See clause 5.4 of the End User Licence Agreement for details.

9. When does my licence for using this data expire?

You are only licensed to use these data for the period you qualify as an Authorised User.  The definition of Authorised User is given in the End User Licence Agreement.  If you no longer qualify as an Authorised User, for example, if you leave your institution, you must delete any data you have downloaded. See clause 5.4 of the End User Licence Agreement for details.

10. I moved from one institution with a subscription to these data to a new institution that does not subscribe. Am I still allowed to use the data I downloaded?

No. You no longer qualify as an Authorised User. You must delete any data you have downloaded.

11.  Can I use this data for commercial purposes?

No. You may only use the data for Educational Purposes as defined in the End User Licence Agreement.

12. I want to collaborate with others; can I share this data with other researchers in my field?

You may only share the data with others who are also Authorised Uses. Please check the definition of Authorised User in the End User Licence Agreement. Note that it is your responsibility to check whether an individual is an Authorised User or not prior to sharing any data with that individual.

13. I am publishing my research, which includes images from this dataset. Is this permissible, and if so, how do I reference it?

All notices and acknowledgements which must accompany the publication of any images from these data are given in Appendix 1b of the End User Licence Agreement and vary depending which dataset has been used. Note that you may need to include more than one notice or acknowledgement.

14.  Are any of these data open source (i.e. available to anyone free of charge)?

"Free of charge" should not be confused with "Open Source".  The data themselves are free of charge, although still subject to the terms of the End User Licence Agreement.  This does not make them "open source". The subscription fee paid by your institution, which provides you with access to these data via Digimap, covers the cost of providing the service. It is not a fee for the data. The same data may be available from other sources but may also be subject to a data processing or delivery fee.

15. What is the correct copyright statement to use?

Each edition of the CEH Land Cover Map data has a different copyright statement and list of required acknowledgements. Please see the Copyright and Acknowledgements page for full details.

Land Utilisation Survey of GB (Dudley Stamp) FAQ

1. Is the data available to download?

No, at the moment the Land Use maps can only be viewed on screen or printed locally.

2. What is the correct copyright statement to use?

If you incorporate the data within your own work the following acknowledgement should be cited:

© L. Dudley Stamp/Geographical Publications Ltd, Audrey N. Clark, Environment Agency/DEFRA and Great Britain Historical GIS

3. There are white gaps, discontinuities and the shading of the map changes across the screen.

The maps show in the Land Use Map Viewer have been scanned from paper maps. Where the edges of these paper maps has been distorted due to wear and tear there will be gaps. Warping in the paper maps will lead to discontinuities between features which appear at the edges of map sheets. Since the maps have been sourced from multiple source collections and these collections may have stored the original paper maps under different conditions there are bound to be changes in the condition of the maps.

4. What can the data be used for?

This resource is supplied free to all UK higher and further education establishments for the express purpose of supporting teaching, learning and research. Commercial exploitation is strictly forbidden under the current licensing arrangements. If in doubt please consult staff at EDINA.
