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.
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.
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.
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?
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
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?
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? 😐
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
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 ?
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
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.
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 :)
Data from google earth is not really suitable for that. Ideally, you would be looking for actual bathymetry data done using techniques such as depth sounding
@@geodeltalabs I have tried extracting land n marine area data from Googleearth like your explanation. Marine area always zerro. Ok .. thank's, I am trying download from Gebco for bathymetri
the lecture is very interesting I am attending attentively. I don't know what steps I lost; from the input (C:\Users\lenovo\Desktop\20230127050417-44037-data.gpx) the output also comes (C:\Users\lenovo\Documents\ArcGIS\Default. dB\c2023012705041744037data_GPX). It would be very help full if you advise me know the mistake I did. In advance thank you so much.
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!

Concise, Clear and Topical. Excellent Tutorial. 5/5 !!!
Thanks :)

Ur voice is amazing sir.....Clearly presented...
So amazed how there are endless possibilities in these softwares!!!!
You are right! :)
Amazing tutorial. Thanks a lot for this wonderful video!
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!
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.
I do it but mine does not contain elevation values at all
mine also

Create raster with 20m resolution --> resize to area you want --> raster to point --> voila!
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
I do the same process but I faced a problem. when I open the attribute table it shows elevation is 0. what to do?

Check your projection.
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?
Can I make a grid of points, say, in QGIS, then import it to Google Earth and export it with the elevation data?
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?
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
I can see the altitude difference in the elevation profile, but when I export to KML or KMZ the elevations just shows zeros
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 can we convert gpx file to shp in qgis 3?
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?
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
Awesome but can you perform a similar manipulation in QGIS?
Thank you so much...and what if the cell size when working with UTM.
How about depth data? Will it still work?
i am not able to use this technique with seafloor height , any way to find that too ?
sea level is technically zero (0)..
Wow. Learning more with your tutorials.
thank you so much! it's too help for extracting elevation-from East Timor
How to solve the situation that the elevation data is zero in ArcMap?
It gave me coloured boxes instead if elevation map after using kriging spatil analytical tool
Can we use EAsyGPS in place of ArcGIS?
how to do the same with the seabed?
Thank you! but can you get climate data on each elevation point?
This was awesome! What if we want to generate elevation profiles for this whole area? How do we do that?
Your video is amazing..
Thanks
I'm getting a bad map with this which I think is because of this: "Coordinates have measures: No" and I don't know why that is
This has been tremendously helpful. Thank you
You're so welcome!
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
You do an outstanding job of explaining!!
Thanks :)
I was receiving an ever when I applied for kriniging?
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...
great tutorial btw keep up the good work!!!
Thanks
Elevation data is not showing in the attribute table what I have to do
Sir my data source don’t show coordinate system.. how can solve it?
Gpx to feature conversation, FAILED to execute.
Arcmap 10.3.1
Please can someone guide me??
That's amazing. I like making my own maps for hiking. 👍
Great!
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
when i try the process i keep getting an error message that says 'output feature class Empty'
Thank you, what is the source of the altitude, terrain data in GoogleEarth?

@@geodeltalabs 👍👍👍
Please make video on zonal statistics.. I only understand you and no one else
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
Thanks Sir quite helpful, please is it possible to use polygon while drawing a given area instead of lines?
very helpful video for my research work .thanking you
Very nice. Very well explained 👍

Mximum useful for Arcgis Learner
can this be exported to 3d like .fbx?
its already 3D..
very nice videos, learned a lot
Can’t we do this in Q- GIS tool??
yes, its possible with QGIS as well
Where to find gpx in archgis
can be this elevation be also transfer to auto cad?
Thanks.very very usfull lesson .
ARC map is a free and open application?
No, it's a commercial product. The free and open source alternative to this is QGIS.
Great video. Thank you 🙏🏽
fantastic 🌹❤️🌹
thank you so much
Amazing! Great Work
Thank you for the tutorial. So helpful! Can you please help extract DEM for Dimapur District, Nagaland, India?
No
please please.... make a video on Extracting Elevation Data using QGIS Thank you :)
Thanks. Useful one
very good one thanks a lot for you
You are welcome :)
Wonderful tutorial!
Great video,how do ceate th using Q GIS
Hello mate thx for ur efforts.
Can I get a polygon shapefile by this way?
Where i can get a Arcmap?
You can head over to ESRI's official website :)
well explained.. thank you so much
Great stuff. Thank you.
this is so cool ahhhhh thank you king
You are welcome
Great channel. Thank you !
great video. i am grateful
Elevation are not show in attrubated table
Highly helpful 👌
You are welcome
thanks for sharing tutorial.
Hi, great video and really enjoyed it. How do you get your elevation in feet? I see that your contours are in meters.
extremely helpful thankssss
greetings from pakistan sir, can you prepare 2d hec ras modelling and flood mapping for us.
Will look into that. We plan to do some tutorials on hydrological and hydrodynamic modelling using open source tools as well as commercial tools
@@geodeltalabs Please do that. Can't wait for this tutorial
Thank you so much
Great job, man!!!
I cannot get the elevation data
It works. Thank you
