UK 30M or close elevation data?
WHM70
Global Mapper User
Hi, I'm trying to track down a high resolution elevation map for the UK. I currently have access to a 100m SRTM tiff. While this is great at many heights, it's not holding up when I get in close. I would love to double it or perhaps do better. Is there a viable source for this? In particular I don't really have time or the skill to merge or repair data, so a commercial source may be the best bet. Finally, I haven't got Global Mapper running right now. The only PC in my office is out of action. So I apologise if this would be easy through the software.
Many thanks,
Will

Will,
Your best source for high-resolution elevation data for the UK would be www.intermap.com. They should be able to provide up to 5m resolution elevation data if you need it.
Let me know if I can be of further assistance.
Thanks,
Mike

Thanks Mike, I've been in touch with Intermap. I was a little shocked at the cost and may have to try something altogether different.

You can increase the vertical exaggeration of the 90m SRTM data, which helps a bit. I doubt you will find any low cost alternatives that provide higher resolution than the SRTM data set.
I just finished a UK terrain map that merges the SRTM data with Blue Marble imagery. Look sort of like

OSGB (Ordnance Survey Great Britian) have avaliable free data at a 50m grid I think. It is called Land-Form PANORAMA® and is available here https://www.ordnancesurvey.co.uk/opendatadownload/products.html It is not update but should be as good as the STRM and is available in a number of formats Should be free of holes and other errors that occurin the STRM data
