Do search engines make use of IPTC Core metadata?

I'm using Bridge to organise a large group of maps (the maps are JPEG images), which will be published on my organisation's website. These maps are about niche topics and very specific areas of the UK.

I'm wondering if there are any SEO benefits from adding IPTC Core metadata to these map images using Bridge? Does anyone know if search engines use the meta?

Thanks in advance for any ideas.
