Great video and explanation! It was so easy to follow, thank you. I'm not sure if there is another video but it would be great to also see how to export to various formats such as dwg.
Hi Profassor, I appreciate thank for yoour video. But i ask your help that I can not convert the latitude/longtitude to UTM because after I convert be same old. so could you give me some advise?
Hi Charlor. Thank you for your positive feedback. Regarding to your question, I recommend to follow the tutorial step by step to finish the process successfully. The video has almost 4000 visualization and none reported any issue in the process. Maybe your problem is due to a different factor no related with the tutorial. Please, try again step by step and let me know where you get stuck, if it happens again. Cheers.
This is really great information, it would have been even more awesome if your voice hadn't been obscured by the music track overlaid. As a learning experience the mind does better with fewer inputs when trying to assimilate new concepts, patterns and knowledge. For anyone with a hearing deficit your brilliant work becomes unusable. Thank you so much for making these tutorials the time and effort required for such a commitment is really appreciated.
Thanks Marcel for the video. It is quite explanatory and easy to follow. Can you please explain why you had to Change the Coordinate Reference System (CRS) from WGS 84 (geographic) to NAD 83 Z11 (projected)? Is this conversion required in all cases of contour line creation from GoogleEarth? Thanks
Hi Adbulfatai Tunde-Lawal, this video is the first lesson of a course with a total of 3 lessons. One of the goals of the course is to compare the digital elevation model (DEM) created with data from Google Earth with other DEM created with LiDAR data. In order to compare both models we need to have the same CRS. The raw data from the LiDAR file was NAD 83 Z11 and because of that I decided to use the same CRS for the model created with data from Google Earth. NAD 83 was very popular in North America in the 80s, 90s and 20s and most of the data was collected with that CRS. Also, the data from the LiDAR file was projected and it is good because I can measure the distances in meters. To work with geographic data is more complicated and you are going to use geographic data when you want to represent a big extension without deforming the surface. In this particular case, the best option is a CRS that is projected. cheers.
Thank so much for your instruction. But the problem is my location don’t have NAD 83 , it only have WGS 84 ( wgs 84/utm zone 49N). So I still follow your instruction, just used CSR : WGS 84, or I have to do more step/ convert ???

Thank you so much for the positive comment. The new tutorials do not have music, just the voice. I am totally agree with your opinion. Thanks again.
Very good 🙂
