Visualisation of this data just makes you think how weather patterns would of been affected by these forrests. It's obvious now that these forrests are gone, what we have lost.
Just found your channel (One Blend Mode Vid) and after watching that & this too I am officially hooked. Can't wait to delve into all your great content. Thanks :)
Yet again I have enjoyed watching you construct a cool looking map. I find it very informative watching you dive into the symbology of layers and how you achieve those clever effects with just a few clicks. Thanks for sharing
Thanks for sharing your workflow here. One question is how would you straighten out the map's borders after georeferencing and dealing with map warping (9:15 for reference). This is something I'm struggling with when georeferencing maps of larger areas. After aligning the DEM and Base Map I want a finished 3D map with the original 2D map size and aspects. Thanks in advance
i think the best hope you have is to know the vintage map's projection and match the GIS to that projection. then there should be little to no distortion at the edges.
Hey, cool video, but wouldn't it be easier to put a grid on the basemap and use this for the georeference points? I tried this to, but had a lot of struggle to find the right projection for those old maps. Do you have any extra advice for that? :)
funny, that is exactly what i did (adding a grid and using it to register while georeferencing) for the actual map used in the book! it actually turned out to be only marginally helpful since figuring out the grid intersections between the vintage map and the grid layer was actually more cumbersome than just using state boundaries. unfortunately, it's pretty much educated guesswork when it comes to guessing (or getting close to) old maps whose projection is unknown. thanks Token!
AHHH assistance please. After adding the Conus layer, the symbology shows up as 7 classes with unique values, ranging from red to blue (instead of the black-to-grey hillshade that you had). I tried changing symbology to black to white, but am unable to add it to the Elevation Surfaces grouping. Do you have any suggestions, all-knowing John Nelson?
Hi John! I'm looking through your videos to try to find the solution to this problem: I want to show and exaggerate elevation data, but only show over a certain height (certain mountains). I saw that you did this to get rid of negative elevation data in the past with DEMs but can't remember what video it was.
if it were me, i would use the "math" tool of the "raster functions" tools to subtract your baseline elevation from your input elevation layer. i do something similar (inverting) here: th-cam.com/video/yB7Ca86xdcA/w-d-xo.htmlsi=rgtojk1W_53q-zkp
Hello dr. Nelson I add the carbon layer but it just cover forest areas not all of the the united state area. I would be thankful if you tell me how I can solve it Thanks

I am your density.
YES. that's all i heard while i was editing this.
At 8:10, when I don't add a much-needed pin in Brownsville, TX, I drive myself mad in hindsight.

well rock and roll, thanks Patrick!
You have outdone yourself once again! Great vid as always John!
thanks Yuhao!
This is GREAT, John! Map magic!
thanks Jim!

wow thanks Duncan!
Hi John, this is awesome, thanks for sharing. I'm glad I found your channel!
hey, thank you Carols! happy mapping!
John, that is really cool! I will definitely have to try it. Thanks for all your great map hacks.
Hi Crystal!
Thank you so much once again for both instruction and inspiration!
Wow thanks!

Thanks @@JohnNelsonMaps. Do you have any suggestions or resources for finding the correct projection for any given vintage map?
Hello John from the Netherlands, i can't drag my data from 2D-Layers to ground. I was wondering if you know how that can be possible. 11:00
it has to be a viable DEM (digital elevation model)

@@JohnNelsonMaps Thank you for your fast respond =)
Great map! I have a question..How did you edit the photo to make it so before uploading it to ArcGis? Thank you
I just used the eraser tool in photoshop to erase the not-map parts. you can skip this step though if you want. it was just for aesthetics.
@@JohnNelsonMaps I was going to ask the same thing. Thank you!
Your content is great
Thank you Skye!

in the "primary symbology" dropdown at the top of the symbology panel, choose "stretch."
@@JohnNelsonMaps Thanks, it worked!
@@crys7868 great! have fun!

Nice
Thanks!
Could you tell me is there any carbon layer for another location on living atlas and could you tell me how I can do this for another location?
good question, i don't know. this one comes from the US Forest Service, but I'm not sure of other nations or global data.
@@JohnNelsonMaps thanks for your response. Could you tell me how I can create this layer. Is there any tutorial for creating this?!
@@simateimourianmotlagh2023 I’m sorry I don’t know how to create a carbon mass layer.
Hello dr. Nelson I add the carbon layer but it just cover forest areas not all of the the united state area. I would be thankful if you tell me how I can solve it Thanks
is it the same layer that i added in the video?
