Lidar Sources (UK Commercial and Free)

I'm always looking for UK free LiDAR sources on the web. Some of the useful (sometimes non-free) ones I've come across are listed below. https://www.english-heritage.org.uk/professional/research/landscapes-and-areas/aerial-survey/archaeology/lidar/ english-heritage - the light fantastic data.gov.uk/dataset/lidar-digital-surface-model vterrain.org/Locations/uk/ lidar-uk.com https://www.geomatics-group.co.uk/geocms/ geomatics-group uk catalogue shapefile Andrew Richman Presentation https://www2.getmapping.com/Products/LiDAR http://catalogue.ceda.ac.uk/uuid/7f1280cf215da6f8001eae5c2f019fe8 http://www.lidar.co.uk/ http://www.lidarbasemaps.org/ http://lidar.cr.usgs.gov/ If you know of any more please let me know so i can make this a definitive UK listing for Commercial and Free Sources of LiDAR.

Grass 7 Beta 4 just announced.

Hope you are having a great Christmas. Just wanted to remind the Free and Open Source Geospatial Community about the Grass GIS 7 (Beta 4) release of a couple of days ago. My apologies if this has been copied to social media sites but worth mentioning non-the-less. As a huge fan of this workhorse of a product it has some major new enhancements and features in order to bring it more in line with the rest of the wxPython Geospatial Community. Have a look at the following link: http://grass.osgeo.org/news/39/15/GRASS-GIS-7-0-0-beta4/ Below is a quick example (exported as an animated gif) of how easy it is to produce a series of raster map overlays onto some base lidar data (using the 'r.lake' module and the new animation module) in order to get an idea of the effects of rising river water levels over a thousand year period as a result of global warming at the current sea level rise of 3mm per year (for this demo no other environmental factors have been taken into account).
