# 8. Licensing and use restrictions VHR data is generally commercial, rather than freely available. Therefore there are licenses and use restrictions that end-users are required to agree to, when using the data. End User License Agreements (EULAs) are available when imagery is licensed, but it is also important to be aware that they are subject to change. They include information on attribution to use, and when, how and where you can use the imagery and any derived products. MAXAR has their [EULAs available online](https://www.maxar.com/legal). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://guides.geospatial.bas.ac.uk/10-things-to-know-about-vhr-satellite-data/8.-licensing-and-use-restrictions.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
