[Talk-GB] Environment Agency LIDAR datasets OGL licensed now available

[Chris Hill]

Thanks for the plug Tim :-)

The slippy map with relief tiles made from the data and optionally 
contours also made from the data is here: http://relief.raggedred.net. 
This covers a mostly very flat area, yet significant details are 
visible. It does show a number of places where ditches and other small 
water courses might be missing from OSM and therefore places to survey.

The contours are minutely detailed using the 50cm data. If I was 
creating contours that are more generally useful I'd try the 2m data I 
think.
