Geospatial Map Visualizations in R

[@juansanchez7713]

Your videos are great, thank you!

[@BusinessScience]

Wonderful! Glad you enjoyed it :)

Thanks for sharing the video. could you tell me how I can set the Robinson projection for my world map and how i can choose some countries by names?

[@vohoanghac2675]

Thank you, sir. I was looking for this

[@BusinessScience]

Glad I could help! 🙌

Nice one

[@BusinessScience]

Thanks for watching

[@haraldurkarlsson1147]

Nice - It would be nice to see more examples. For example with data covering more limited regions.

[@BusinessScience]

Sounds great. I’m doing a whole geospatial learning lab series. This will be more in depth covering geocoding, simple features, mapview, and a lot more.

thanks for video!

[@BusinessScience]

You got it!

Hello. I'm relatively new to R for spatial analysis and just recently came across your channel. Was practicing this code for an upcoming project and wanted to make a cool 3D orthomap like the one you made at 5:15. My line of code won't run. It returns an error for using the '+' sign. What operator can I use to avoid this error? Tried piping, still won't let.

[@BusinessScience]

Do you have experience with ggplot2? The + adds layers to the plot to build it up.

Could you comment if it is feasible to modify for Canada data from the following line? usa_tbl % as_tibble()

[@BusinessScience]

I believe this is just for the USA. Check the documentation though to be sure.

[@jususlovesus]

thank you very useful...how do you label names of the countries on map?

[@adamrogerson914]

Brilliant, thanks

[@BusinessScience]

You got it Adam!🙌

[@gseacat]

Is it necessary to set the map argument in geom_map = world_tbl when you already piped world_tbl into the ggplot function?

[@BusinessScience]

Yes, I'm pretty sure it's needed.

[@davidjackson7675]

Do you have a video on how to make interactive maps?Thanks

[@BusinessScience]

Thanks for reaching out. Nothing yet but I’ll add it to the list. Also students have been asking about animations.

[@rafaexx]

I suggest you to try the sf package to read your geospatial data and then use geom_sf. That's much better.

[@BusinessScience]

Thanks. Will certainly take a look. Simple features are a bit more complex but the data visualization can benefit.

Thank you for uploading a wonderful tutorial. I have a query that how we can plot two variables data on single map. Like : ggplot() + geom_sf(data=shape, color='grey20', size=0.1, fill=NA) + geom_sf(data = subset(clus_dzc1, type=='high'),aes(fill=CL2),size=0.1,color='black') + scale_fill_discrete_sequential(palette='Burg',name="High-risk",rev=FALSE, guide = guide_legend(ncol=2)) + theme_void() ggplot() + geom_sf(data=shape, color='grey20', size=0.1, fill=NA) + geom_sf(data = subset(clus_dzc1, type=='low'),aes(fill=CL2), size=0.1, color='black') + scale_fill_discrete_sequential(palette='Blues',name="Low-risk",rev=FALSE, guide = guide_legend(ncol=2)) + theme_void() . There are two plots code. Can you please guide me, how i can convert into one gg plot. Can you please write the code for me. I shall be very thankful to you.

[@BusinessScience]

You got it!!

No i did not 😢😢
