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

Hi Chris Would it be possible to somehow use this data with the building outlines from OS OpenMap?. I know that data is somewhat simplified/generalised, but maybe combined together we could get an idea of how the simplified shapes from OS OpenData are terraced and even get their heights. I'm not

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

Hi Tony, As OS OpenMap is vector data, finding the height for any building outline would be similar to using OSM building outlines. Using the DTM data would also give the base height AMSL of the building. I have used DEM data in Blender (https://www.blender.org/) to create a landscape to

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

Sounds good Chris. No problems with imports from me (assuming the data passes reasonable* quality assurance). I do feel that the concerns over imports are preventing OSM from properly innovating. This is a good example of dataset and an innovative approach that has been made available to us. It

(I'll try again ... ) It might well do that. I'll attempt to compare two areas tomorrow and see how easy it is get any height data out. As it happens, one of the areas covered by the EA data that I have worked on is a large village (Cottingham) which has its buildings all traced out, so I
