I am also watching this video because of my architecture studies... can I ask you what program you used after you converted your data to gpx? I can't sign up for the free trial because I can't provide a business email address
Great video, thank you, I'm going to try to plot my land. I will never understand what you did, or how you did it, but hope to get there by following your steps.
This is so helpful! Thanks for uploading! However they are on a flat plane and without height variation while exporting to CAD. How do I incorporate the elevation information to these lines? so I can further import them into 3D software for modelling. Appreciate in advance any tips or help!
There is an way to do it through ArcScene but it's a bit too complex to explain over a comment, maybe look for something like that on RU-vid? There's also a way to export it as a dxf if I remember correctly from QGIS. Alternatively I would imagine a rhino grasshopper script can take values and help you extrude it to the correct values. Sorry I don't have a direct answer but hope you find what you're looking for!
Any possibility of instructions of how to do this on a Mac? I’ve made it halfway through the video and love it but have spent a full day trying to muddle my way through with QGIS and can’t work out how to do the equivalent of what you demonstrate in ArcGIS. Would love your help for all the Mac users out there.
This is only slightly frustrating because you could have just told me that this is basically an ArcGIS tutorial via title. (Free trial not available atm, but even if it was, the tutorial itself isn't sustainable i.e., practically, you'll only use this method once.) Although, I do appreciate the clarity of the tutorial. Here's the tutorial you're actually looking for: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-bLbY3iMBW-A.html
Hi, I'm using QGIS; when you create "Elevationmap", which file type is it? QGIS creates a .TIF by default but when I try to interpolate the contours there are no data sets...
actually I figured that out (was using the wrong tool!)... however, when I create the contours the orignial point grid from the kml is shown over the landscape, as contoured lumps on the surface. I tried clamping them to the sea floor but it did not make a difference. Any ideas? (i would just use ArcGIS as you suggest, but I can't seem to get access to the free trial...)
Hello, thanks for uploading. However I ran into a problem, when analysing the features with the IDW tool, it fails and I tried it several times again and same result. Please tell is if there is a way to fix this
Great Video. I have completed the contour map. Can this be imported back into google earth pro so the contour map can overlap on the path data that the original data was extracted from?
Hi, im having trouble running the ArcGIS. I already have my Trial Account but when i try to login, says that there's something wrong with my clock and i does not recognize me as a user. Any thoughts?
Hi, when i convert the file into points, the features file gets exported into different files on my system but the points dont show on the interface itself… how do i resolve this?
Yes you should be able to but if you're going anything less than a meter (or 5m for that matter) you're suggesting a degree of precision that this method of contour extraction just doesn't have. It should work though!
@@lyh_studio Thanks. Is there any method available fit for that purpose? Here, in India, its very difficult to get any contour map, leave alone the precision.
@@somjithazra If it's within any municipality we usually just use the GIS data from the city (in NA) so maybe try that? Other than that I dont know of one off the top of my head

The contourlines look absolutely nothing at all like the shape i try to map, not even close at all despite me doing everything like shown in the video, sure there is a rough blob where my island sits but thats as far as similarities go, where could i have gone wrong ?
Hey! What do you mean the shape you try to map? Is this a shape that you have built or a part of the world? Did you also draw enough points in google earth for a better sampling?
@@lyh_studio yes its not a large area it's a small island called farholmen near Stockholm and while the island is roughly L shaped I get more of a roundish blob shape. I drew roughly 100 reference points over it
@@clibfilm If all steps are followed then it just might be a case of resolution. I believe the data is 90m resolution, meaning each raster "block" is 90x90m in real life. So if the island is not very big, then the true shape of it will be approximated and won't be very accurate. This method is good for bigger landscapes. Is this for a school project? Are you able to take this into another 3D modelling program and modify it? Or are there no resources on sites from the locality that gives you the contours?
@@lyh_studio it is for a university project, the island is not really big ~280x200m, but its not that high max is 9m above water level. I am currently trying my hands on just modelling it approximately from some rough hightlines i found on a website. I have access to sketchup, rhino and vectorworks, however the sketchup method of importing the terrain gave me terribely wierd results too. Because its only a uni project and we were allowed to choose a place, we got no initial data for the site, it is part of the task to atleast aprox. a topographic model and contour lines
@@clibfilm Would it be helpful to generate a surface in rhino, rebuild it with more than 10 U and V points and then just 'pointson' to edit the surface to your liking? Then with the 'contour' command extract that from your new model? You can also get a picture of the island, trace what you think the contours might be and then generate a surface from that if needed.
