Just so everyone is clear on this, you are NOT extracting the elevation data from Google Earth. The page in this vid uses the location of the points in the path and extracts the elevation data from a DEM model (most likely SRTM-3, though it depends on the location of your study). It says so in the paragraph just bellow where you upload the .kml file. I also tried this method, seeing that, for my area of study at least, the Google Earth topography model was more precise than the ALOS PALSAR data I have available (30x30 m RES, while in GE it seems to be 5x5 m or more from what I have measured). This means that: 1) Unless Google Earth uses a DEM with the same resolution as the one from where the web page extracts the elevation data, you won't be getting the same accuracy. 2)It's better to download the DEM from the source. (The best being the Alaska Satellite facility, mission ALOS-PALSAR and data processing level set to Terrain Corrected). 3)In some locations, Google has access to elevation data that isn't publicly available (like in my case), which allow them to generate super accurate/High RES terrain topography.
Perfect and well articulated. As someone who only knew about generating contours using drone images, I have now learnt even much more from this. You have made my day and trimmed the long process of doing things thanks alot.
Thank you very much for your patience in teaching and making your training very easy to follow. Please can we do the same in QGIS because I do not have Spatial analyst and all other extension tools in my version of ArcMap.
It is really good tutorial, but I think it should be mentioned that the extracted values of height are not really from google earth but from other sources listed by GPS visualizer site
Kriging may not be entirely ideal tool for the process, unless you want some areas extrapolated. You can simply use the density, spline, or (Thiessen polygon - Tin- slope - raster) for interpolation since contour productions works in such manner
Thank you the gourgeus tutorial and i need to know we can make these contour's section to produce a profile and save it in DWG Files that mean it can be used in CAD soft . thanks for your help .
Hmm. 🤔 But if i wanna make a trekking map, with maybe the satilite image in the background so i can visualise the lakes ponds etc etc. How do you do that? 😐
How does GPS visualiser work? I'm using QGIS which will accept KML files so why is it necessary to convert it to a text file? Is it that QGIS can't read the elevations values in the KML or does GPS visualiser add elevation data and then convert it to a text file?
Cool, Thanks for the video. What if we need temporal elevation change of same area like current elevation vs 2015 elevation ? because in my study area dam and water ways are under construction and want to measure total excavation Area ?
How we add a 'lattice grid structure' to google earth as *.kml/*.kmz format? I mean If we create grid points that have equal distances both in -x and -y planes and import it to G. Earth, it can be easier and had higher resolution. I wonder do you know is there any toolbox or any method in ArcGIS to create a grid structure with equal intervals between the points in -xy plane?
Great video. Is there a way of taking the Google Earth elevation data for a small arear and covert in to a height map? maybe with some free software options? Looking to make height maps for small arear up 600 yards and less.
Hi, I think you'd be better off downloading an SRTM Dem and using a free software like QGIS to make a height map, as it would be more accurate and convenient. You may find tutorials for both in the video list :)
Hello there, Google Earth obtains its elevation data from a variety of sources, including SRTM, GTOPO30, and SRTM3. In addition to these sources, Google Earth also uses data from other sources, such as national mapping agencies, to supplement and improve the quality of its elevation data.
Cool video! Do you know if there's a way to export the elevations including buildings and other structures? Because when I tried this method it only sees the terrain. Cheers
This is so random. Not only i was shocked that you chose Malaysia, but you also zoom into my hometown. Thanks!
One of the best GIS tutorial I have ever watched. Many thanks!
Amazing tutorial. Thanks a lot for this wonderful video!
Ur voice is amazing sir.....Clearly presented...
Concise, Clear and Topical. Excellent Tutorial. 5/5 !!!
Thanks :)

So amazed how there are endless possibilities in these softwares!!!!
You are right! :)

Wow. Learning more with your tutorials.

thank you so much! it's too help for extracting elevation-from East Timor

Suuuper............. Thank you Sir
You do an outstanding job of explaining!!
Thanks :)
Hello. Great video. Ive watched your QGIS video and i was wondering if we can extract elevation data and use it in QGIS? Thanks!
I use SRTM plugin in QGIS, quality is basically the same but far more convenient to use
Thanks. Useful one
Your video is amazing..
Thanks
This has been tremendously helpful. Thank you
You're so welcome!
great tutorial btw keep up the good work!!!
Thanks
That's amazing. I like making my own maps for hiking. 👍
Great!
Hi! I'm using QGIS instead of ArcGIS. I also need to extract the contours for every 1 meter. Do you have another tutorial using QGIS instead? thanks!
Great stuff. Thank you.
Thank you.
Thank you so much for the videos, help a lot, so sad I only have the basic license, I am getting stuck with the kriging...
Amazing! Great Work
Great job, man!!!
Mximum useful for Arcgis Learner
Please make video on zonal statistics.. I only understand you and no one else
Thank you so much
Great channel. Thank you !
Awesome but can you perform a similar manipulation in QGIS?
Thanks.very very usfull lesson .
very nice videos, learned a lot
Thank you so much...and what if the cell size when working with UTM.
very helpful video for my research work .thanking you
Thank you the gourgeus tutorial and i need to know we can make these contour's section to produce a profile and save it in DWG Files that mean it can be used in CAD soft . thanks for your help .
Wonderful tutorial!
Great!!! Thanks.
Can I make a grid of points, say, in QGIS, then import it to Google Earth and export it with the elevation data?
Very nice. Very well explained 👍
Thank you very much this is very helpful
You are welcome :)
Thanks Sir quite helpful, please is it possible to use polygon while drawing a given area instead of lines?
great video. i am grateful
thanks for sharing tutorial.
This was awesome! What if we want to generate elevation profiles for this whole area? How do we do that?
Excellent
superb thanks
extremely helpful thankssss
Very helpful, thank you. Question: Why saving the point in KML and not KMZ?
i think , kmz contains vector elements i,e, points, vertices , coordinates (except z value), and kml contains raster elements i,e, z value
very good one thanks a lot for you
You are welcome :)
It works. Thank you
App mujhe batayegi achchhi Google image konse software se milegi .
Ye software theek hai?
this is so cool ahhhhh thank you king
You are welcome

How about depth data? Will it still work?
Highly helpful 👌
You are welcome
Great video, Is it possible to do this on QGIS?
Yes, absolutely!
I have a geotiff file with more accurate elevations than Google Earth. How can I make Google Earth use these data when exporting the .kml?
Very informative
Cheers!
I'd like to export 3D polylines from Google Earth. I want AutoCAD polylines to lift up on Google Earth elevation data. How do I do that?
Thank you! but can you get climate data on each elevation point?
Great video,how do ceate th using Q GIS
please please.... make a video on Extracting Elevation Data using QGIS Thank you :)
I do it but mine does not contain elevation values at all
mine also
Thank you for the tutorial. So helpful! Can you please help extract DEM for Dimapur District, Nagaland, India?
No
Cool, Thanks for the video. What if we need temporal elevation change of same area like current elevation vs 2015 elevation ?
because in my study area dam and water ways are under construction and want to measure total excavation Area ?
have you get the solution.. i just need the answer because its related to my study. tq

Create raster with 20m resolution --> resize to area you want --> raster to point --> voila!
I can see the altitude difference in the elevation profile, but when I export to KML or KMZ the elevations just shows zeros
Great video. Thank you 🙏🏽

Thank you somuch
Can we use EAsyGPS in place of ArcGIS?
well explained.. thank you so much
helpful, thank you very much
Awesome.
Thanks
How can we convert gpx file to shp in qgis 3?
thanks !
I do the same process but I faced a problem. when I open the attribute table it shows elevation is 0. what to do?

th-cam.com/video/aJm9lewzooU/w-d-xo.htmlsi=DhK-E49k7hgk7kuA
Check your projection.
How to solve the situation that the elevation data is zero in ArcMap？
thank u so much
i am not able to use this technique with seafloor height , any way to find that too ?
sea level is technically zero (0)..
how to do the same with the seabed?
Sir my data source don’t show coordinate system.. how can solve it?
thank you
Thanks.Sir.
All the best
I was receiving an ever when I applied for kriniging?
Thank you, what is the source of the altitude, terrain data in GoogleEarth?

@@geodeltalabs 👍👍👍
Cool video!
Do you know if there's a way to export the elevations including buildings and other structures? Because when I tried this method it only sees the terrain.
Cheers
the best way is to copy down the elevation at each point of interest then mark up anheight map in shades of grey.
It gave me coloured boxes instead if elevation map after using kriging spatil analytical tool
god bless you
:)
Hello mate thx for ur efforts.
Can I get a polygon shapefile by this way?
awesom
Elevation data is not showing in the attribute table what I have to do
thanks alot
