Making crisp spike maps with R

This is fantastic!! Thank you for putting in the time to share this with us.

I follow you on twitter and the maps and visualisations are amazing, i had no idea but that you have a YouTube channel too🤩

Very interesting tutorial Milos!

great as usual. Thank you.

You have a very nice tweak of R

Amazing. Great tutorial. I'm looking forward to your next video, as a suggestion, the forest density of a country, using rayshader package.🙂

Fantastic tutorial, thank you. I am wondering how to overlay a shp file containing border and the name of the cities etc with this type of map?

Hey Milos, if I want to replicate the other country, besides change the ISO 2 code (line 28) , the Lambert Projection (line 47) also need to be changed as well right ?

Great tutorial! Amazing work. I am seeing this error when I am trying to export/render the graph with lighting. Any ideas why? Error in rayvertex::validate_mesh(mesh) : !any(is.na(normals)) is not TRUE >

Thanks for the amazing work. My question est literally basic. What's the software you're using? I can't guess. Thanks for all the work

Hello Milos, nice Tutorial, please would this work if I want to try for the European LAU level

Thanks a lot for this fantastic tutorial! I tried to adapt your code for a part of Switzerland, the canton of St.Gallen. Unfortunately, I always get the folloowing error message: Error in rayrender::obj_model(cache_filename, x = -bbox_center[1], y = -bbox_center[2], : unused argument (texture = TRUE) Do you have any idea what my be the reason? Is it possible that's because I used another projection? I switched the projection of the Kontur data to Swiss National System (d.pop_ch <- st_transform(d.pop_st, crs = 2056)), because I had to do some GIS analysis based on that projection.

Great video, thanks for this! However, while running "pop_sf <- get_population_data()" ie. #55 i'm getting the following error : Error: crs not found: is it missing? In addition: Warning messages: 1: In CPL_crs_from_input(x) : GDAL Error 1: PROJ: Cannot open espg 2: In CPL_crs_from_input(x) : GDAL Error 1: PROJ: proj_create: cannot expand +init=espg:24383 +type=crs Any idea how i can solve for this? Thanks in advance!

Great tutorial - very comprehensive yet clear! I really appreciate the time and effort that you're putting into making these tutorials :) I've managed to create the map of Germany using your tutorial, and wanted to try my hand at making another map for France. However, when following the tutorial and I get to the 'get_population_data()' section of the code, I keep getting this error message 'Error: Path exists and overwrite is FALSE'. I'm not sure what I'm doing wrong, or what the work around is, so if you have any suggestions, then that would be great! Thanks in advance!

Hi Milos! Thanks for this series of videos, I'm learning a lot of stuff. One question about this one, basically due to my little knowledge of functional programming: what are you asking R to do exactly with these two lines of code? width_ratio <- get_raster_size()[[1]] height_ratio <- get_raster_size()[[2]] I get what the get_raster_size() function does in general, but I don't get what [[1]] and [[2]] stand for. If you have a link with more information on this topic I'll be happy to take a look!

How can I put labels and titles on the map?

It seems R/my computer is unable to load the very first ggplot() call - I don't have a powerful machine but I thought it would do? Does everyone have a big powerful pc here? Only have an Intel i5 8th gen, 8 gb ram and the stock graphics card... Edit : finally rendered (the first one) but needed quite some time

Hello may I ask about something, I always got this error message when i about to export the image. What do you think is the main problem for this? Is it on my Mac or idk, thank you for your help. Error in rayrender::obj_model(cache_filename, x = -bbox_center[1], y = -bbox_center[2], : unused argument (texture = TRUE)

Nice tutorial. What should be crsLAEA for the Indian region?

Can it be applied to show refugees and IDPs in a country? Or it needs more info
