Hi - you can use the lidR package in R to go directly from a bunch of .laz files to an elevation matrix:

# load lidar elevation data
ctg <- lidR::readLAScatalog("/path/to/your/laz_data/")
las <- lidR::readLAS(ctg, select = "xyz")
dem <- lidR::grid_canopy(las, res = 1, p2r())

La tour Eiffel, Paris

Palais de l'Alma is masked in the data, so its footprint has become a water feature

Cardiff?

Arc de triomphe, Champs-Élysées, Paris

An upside to taking an absence from posting for 18 months is that fantastic new data has appeared in the interim.

yep, using the rayshader package in R by @tylermorganwall.bsky.social

#30daymapchallenge Day 30: The final map

Vienna, Austria. The final map I posted to the other place in June 2023 before my Musk-ation, cropped to the 50MB bsky limit. LiDAR www.wien.gv.at/, overlays @openstreetmap.bsky.social, rendered in #rayshader #rstats #maps

Time to make some new things now!

Just encountered this too, that 50MB limit is a little annoying!

Moving another of the archive over, here is Lighthouses of Ireland, UK, Northern France and Belgium. Data from
🇮🇪 www.irishlights.ie
🇬🇧 www.trinityhouse.co.uk
🇫🇷 www.shom.fr and in particular
www.nlb.org.uk for lights of 🏴󠁧󠁢󠁳󠁣󠁴󠁿 and 🇮🇲. Additional data from msi.nga.mil and @wikipedia.bsky.social

Lucky you, I'd love to see the race village and the start!

Yes please!

That is wonderful, Julian

Thank you! I've made a few of these lighthouse maps over the years, I'll post them over the next couple of weeks

Thank you, it's nice to be back, looking forward to making some new work!

Thanks, Terence, not sure I would have embarked upon it if I'd known how much work would be involved 😂

Full of hope that Bluesky will become what the other place once was, so here is a repost of Lighthouses of France 🇫🇷
