- LiDAR imagery has revolutionized the way people study the Earth, human culture, and plenty of other subjects. Geology has never been the same since high-resolution LiDAR started becoming widely available in the early-mid 2000s. Today, the USGS offers a high-resolution LiDAR viewer that you can access for free to explore the landscape in a way that humans have never been able to before. This video shows how to access the LiDAR viewer and showcases a few interesting spots to give an idea of what you can see with it. West Virginia's LiDAR viewer is also previewed. Be prepared to spend some time scrolling around with this if you like landscapes, geology, looking for old gold mines, or finding new adventures.
I looked up a lidar map of my property a few weeks ago after watching one of your videos. In the image there was a clear line running from my shed into the woods for a few hundred feet. I did not remember seeing anything like that so I went out to investigate. Sure enough it was there. A small raised strip a yard across and less than a foot tall running off into the woods. It looks like an old property boundary from a hundred years ago when the area was all farm land. Amazing that it can be measured from space.
This resolution of detail is generated from planes flying patterns over the landscape. Got even higher resolution drones can fly automated patterns to map an area. This is used for construction projects.
May have also been a way for controlling water run off.
I don’t know where you live but the remains of the civil war trenches around my house look like that on the map, but in the woods you would barely even notice them.
Space isn't real. Haha jk
Omg so friggin cool
Thank you, you gave this West Virginia boy something that'll keep me occupied for hours. Never knew this was available.
USGS is my favorite government department. They offer so much valuable information. I often check their site for information on river levels (kayaking).
WOW ! Just looked up my property in Washington state! Amazing tool ! Thank you !
You might be able to find gold with this. Not directly but like ancient rivers could be exposed or granite faults. I'm 61 and waited for all these technologies to happen like phones where you can see who you're talking to or a recording studio in my house, just amazing stuff going on. You are getting a lot of views need to ask for subs more.
You can definitely use it for prospecting! Lots of people do. Just finding old pits, trenches, and workings that are buried in forest is a good application for it. We pass through old gold and mica mines all the time in western North Carolina mapping landslides with it. It's interesting to think about how much of the landscape used to be worked heavily and is now covered in trees. There's much more tree cover in Appalachian now than a century ago.
I guess I might ask for likes and subs. I admit I didn't want to direct people too much. Hope they enjoy the stuff. It's interesting to think about!
yay! I asked about LIDAR sources in the last video. Thanks much!
What is the GIS software you use and the source of the LIDAR data? I realize these both may cost money.
still seeking answer to this. Is it ArcGIS? any alternatives to what he is using? I may be able to get a student ArcGIS license for a 1 year term.
Arc should handle the layers. QGIS is an open source alternative. There are robust geospatial packages for R.
@firerose7936 how does QGIS compare to ArcGIS? Used ArcGIS last semester for my class, and really enjoyed it.
Thanks for giving up your lunch break to create these lectures!
I used lidar to measure/assess some landslides in Idaho a few years back, absolutely love the technology that allows us to do this kind of stuff
Your job sounds awesome I love bushwhacking and looking at maps. I really appreciate you sharing your knowledge and resources with us! I feel like only good things can come from more people looking at and learning how to utilize LiDAR.
I'm going to see if I can find some potential new boulders or arches in the Red River Gorge before my next trip.
Excellent resource! Thanks for posting.
The Slumgullion Earthflow in the San Juan Mtns of Hinsdale County, Colorado is pretty cool in the LIDAR!
Phillip you are too good to me, handing me this Grade A educational gift. All my blessings toward you bro, pay it forward! :)
The Woodbury-Manchester impact crater is very apparent in the stretched LiDAR. That’s so cool.
Well, that's going to keep me busy for a while! Thanks for the video explaining how to use it.
This is like Christmas in August! Thanks for sharing this site!!
Your knowledge is impressive, but your freehand drawing in paint is incredible! 😂
oh my gosh ... I haven't even started watching the video and I'm excited! I have so many questions about lidar ... I'll be patient and watch your video first!! lol
I grew up in Louisiana and maybe I was wrong but we had little surface geology. Then we lived in WY and ID for several years and just seeing the surface features was incredible. We're in TN now and it's this cool mixture.Thanks for sharing this tool to help me understand what I'm seeing.
Thank you so much for sharing this!!
It’s neat that you can see sink hole openings in the TAG region really clearly using LiDAR. Walls of Jericho looks cool in LiDAR too.
Thank you so much! This is awesome.
I peaked over california and there is a 350 mile section that seems to have slowly separated and is being forced out towards the ocean. This tool is going to be fun
😂
Awesome USGS video as well!
When I first seen what LIDAR was and could present to map enthusiasts such as yourself and I'm sure alot of your subscribers. It's fascinating and can occupy alot of your time if you're not careful 😊.
Love this format! You need to team up with some of the other UA-cam geologist out there. Spread the word.
We'd have fun. Put in a word for me! Lots of cool stuff to see out there.
@@TheGeoModels I gave Professor Nick Zentner your link, hope he clicks on it.
@@LDJSFGKJSFDOUKJ Right on man!
@@LDJSFGKJSFDOUKJ and Shawn Willsey and Myron Cook and GeoGirl. Dr Prince belongs with the whole geo UA-cam leaders.
I've driven on Route 14 through the Big Horns and it is amazing.
I remember it being pretty cool. The two slides there in the Buffalo Tongue area would be awesome to see again with the lidar eye. I also remember the red Chugwater (I think) outcrops down at the foot of the uplift. Cool area for east coast geo folks!
Awesome! Still would love for you to explore near Altoona PA for me! Cool curved mountains.
Just seen your reply from last video. You’re the man.
it is actually pretty good up into Canada too. The mountains east of Montreal look even weirder on this lidar then google maps. I believe those mountains are the remains of volcanoes and the softer rock around them eroded away. If you zoom out though it looks like they are rocks on the bed of a river.
Yeah looking it up those mountains known as the Monteregian Hills are intrusive igneous rocks believed to be associated with the new England hotspot track after it reemerged from beneath the Laurentian shield(where it is apparently mainly linked to kimberlite pipes and gravity anomalies).
The riverlike track you noticed thus might be where the hot spot worked its way through the continent leaving various igneous remnants such as the white mountains of New Hampshire?
Thank you. This was very helpful.
I love the shout out for HP40.
somebody got to do it!
lol I was wondering this myself watching your latest video, great timing
Hey man, love your vids. I use lidar regularly to discover climbing areas in Wisconsin. You ever look into the geology of the Baraboo and the driftless areas of Wisconsin? I feel it shares some similarities to Appalachia.
What does glaciation in Appalachia look like? I know you talked about the ice sheets creating Lake Monongahela, and obviously, we have Mount Washington, but how far south did glaciers form? The Doll Sods? Shenandoah? Mount Rogers? I would love some lidar images of what the impacted areas look like today and how the structure of our mountains affected their frozen weathering or lack there of. I LOVE this channel!
yeah that’s a good one. see what I can do. the “almost glacial” stuff in Pennsylvania is some of the best
That it the coolest geologic image I think I’ve ever seen.
I’d love a video on how these layers of rock actually form inside the earth. It seems like you get all sorts of patterns, thin layers, thick layers, layers of rock sandwiched between other layers. What causes all that difference? Why isn’t the inside of the earth mostly just the same stuff?
Dark mode your browser please bro. Love the videos.
Thanks. Hate to sound dumb, but is the dark mode for my own eyeballs or for screenshared vids?
Can you talk about Mountain Lake, how it formed and why its level fluctuates so much? One of the most interesting features near Blacksburg. Tons of great lidar work coming out of VT!
Thanks so much for this!
You should talk about Veadawoo here in Wyoming. That place has some pretty big and cool boulders.
7:40 "I'm just visiting" aw man visit anytime!
It's a good one!
Well shit… now I want a geology degree
Very cool
I believe you can see roads in the bottom of some of the man made lakes sometimes in lidar
Bro! Thank you!
Wow, Puerto Rico has some actual decent lidar. this is pretty cool
yeah with hurricanes etc it’s been a place of interest for landslide studies etc
OK in your Horse Pens example, just north you panned past a ridge with these wild overlapping flatiron-like features on the side of a ridge that are tiered in a kind of interlocking form that looks like snake scales. Really visible at 1:18k scale at -86.270, 33.960 long/lat decimal degrees.
Could also search for Lake Sumatanga AL
There are some dome like features on Pigeon Mountain in Georgia. For example see 34.73129° N, 85.34521° W. I’d love to see a video with an explanation of what those are and how they formed.
Wow, thank you brother. I tried to do this and was totally lost a month ago. P.S. Nice Tundra RC plane.
another one! good stuff, as always. As far as ive been able to find, "waffle rock" by jennings randolf lake is a mystery. I don't have access to college level information though, and the internet doesn't turn up a lot outside of conspiracy theory nonsense. Is there really no explanation to how this rock formed, and is there any other analog rocks around the world we can compare it too?
your channel is one of my favorite new finds, thank you for your work!
You are the man............I live on a slip..........lol...lol...lol.
Neat thanks for sharing Phil. Look forward to your videos any week. Any chance you wanna talk about how you process it for google earth quickly?
This is awesome.
For all of us not living in the Americas, do you have links for how to access equivalent mapping in our own lands?
This is so cool thank you
How’d ya skip that half circle in the bottom right of the screen in Illinois?
cause I ain’t made that vid yet I am trying not to tip off the westerners! it’s a cool story
@@TheGeoModels bad ass!!!
Have you tried matching the rippling on those there mountains with know recent landslides.
The sunklands in MO
We just got this public in Croatia! But it isnt as accesible as the USA version, you have to give all your data and the exact area you want to receive a map of, then the goverment will maybe send you the lidar scans
This what have always waned to since my first archeological dig: WHY IS EVERYTHING OLD BURRED UNDERGROund? No matter where in the world dig a hole and the further you dig the older you go? Where does the dirt come from? I went on a dig in school and at 1" we found native people arrow head flakes everywhere in nh by the river at 2" we found 2000 year old bone tools? Why does dirt rain from the sky and not wash away?
Look for eroded landscapes, look for discontinuities, and look for really old mountains that were once like the Himalayas and have since eroded down to hills you can walk over. That's where the dirt came from. You can't see it because it's not there any more, but you can see where it used to be.
This is wonderful, thank you! Was there a way to download the data off USGS and import it into Google Earth?
What do Indian burial mounds look like on Lidar? How about strip jobs in Eastern KY, Southwest VA, and WV?
Hi. may i ask what application did you use for digital handdrawing? i am a geologist too and researching sandbox modelling using PIV.
Have you thought about doing classes? I’ll buy a ticket
My first hit is gonna be granite city
How can i clip the raster file of the 3D imagery in QGIS?
Sometimes my brain reads the grayscale backwards and then it suddenly sees it correction and WOW that's a strange moment.
it’s a real issue. zooming in and out helps some. it’s why I use the overlays when I can!
Those are balls
✨️🙂✨️
I cant find any program to use lidar esp not free
Southeast KY is all low res for me….
Yeah it's got its own viewer like West Virginia. They run a lot of their own mapping. Search for Kentucky from Above and you can probably get a link. It would go to a similar style of viewer to the others. They do have high res lidar for the whole state.
You can also use lidar to prove there is no curvature to earth.
Shhhhh...dont tell anyone about the big horn mntns. 😊
I hear you. I only drove across on 14 but it was quite nice. The forelimb on the Sheridan side was really cool, from a thick-skinned mountain range standpoint. I'd like to go back!
Geology and forestry aren’t so different
