This was very useful, the Quickmap part and the georef. part. I have tested it, first was with the same resolution as you were using 0.01, but it took 30 min to convert to raster and the file was 3Gb, in the second test i changed it to 0.1, that was a lot faster approx. 10 seconds and the file were 18 Mb
Hi Frede Callesen. Thank you very much for sharing with us the information. You are right, when you are using 0.01 is for satellite images with a very high resolution, in general 0.1 is really good and enough . Sometimes, there is not differences between 0.1 and 0.01, it depends on the original satellite image resolution. If the image does not have a high resolution it does not worth to download with 0.01. Cheers :)
Thanks, it's very useful. Can you tell is there any way to get the previous years Google satellite image in Qgis. Is there any option or plugin to choose date also?
Hi Mohd Zaid. Thank you for the comment. Unfortunately, I do not know if there is a plugin to do that. The only way I am thinking to do it is using the method from the old school, I mean, print screen in high resolution from Google Earth, pick up four UTM Coordinate points as a reference and the georreferencing with QGIS. I have a video tutorial about how to georreference Raster images: th-cam.com/video/LoVe2IAQiHw/w-d-xo.html It could be an interested topic to do a video tutorial, Thanks.
Just wondering... Instead of georeference Google Earth images, why not digitize vectors directly inside QGIS (using the satellite image of QuickMapServicies) and after that reproject them?
Thanks mate for the video. I have a question, why did you put 0.01 in Map units per pixel? What's the reason? Are there parameters to define that? Thank you for answering
Hi Michael. Thank you for being active at the comment section. The resolution of the Google images is changing a lot from one site to a different one. Some areas has really high resolution and other areas is really poor. I am not really sure what is the highest resolution that you can get in Google satellite, maybe 0.1 m x 0.1 m by pixel, but I can be even less. Google is updating the images constantly. With a resolution of 0.01 you are going to have the guarantee that you get the maximum resolution for sure. However, I do not believe that google satellite has any image with that resolution (but you never know). Then, if you are using a value of 0.01 you are going to get an image with a pixel resolution of 0.01 m x 0.01 m, in other words, each pixel of your image has a dimension of 1 cm x 1 cm. This is a very, very, very high resolution but be aware that if the image in Goggle satellite has a different resolution you are no going to improve the resolution, the maximum resolution you can get is the resolution of the original image. With a value of 0.1 you are going to get an images with a pixel resolution of 0.1 m x 0.1 m, and etc. As smaller is the Map units per pixel longer is going to be the computation. My recommendation is not to use a value less than 0.1, but if you think you can get a better resolution you can try 0.01. Cheers!
Hi Jerkins. This is a really good question. It depends on the resolution of the google earth satellite image. In some areas we have a really good resolution but in other ares the resolution is not that good. However, google does not tell us what is the resolution of the image. Perhaps, the best resolution you can find in google Earth is about 30 cm x 30 cm pixel and the worst has to be the order metric, for example 5 m x 5 m pixel. Even surveyor, can work with different resolution, depending on the instrumentation and technology they are using. Each project has different requirements and you have to know how to adapt to the information you really need, it is a balance between time and money. Have a good day.
@@GeoRGBCommunity thank you so much I’m working along with your videos to create the full map as I have an interview where I need to show how to use this software and what you are providing is excellent thank you I may need your help please be on standby thank you again your amazing 🙂
Hi GR33N TauRu. Once you complete all the process and you have the final image, you don't longer need internet connection. Then, you will be able to use the image offline.
Thanks for the helpful video GeoRGB! I have created a workflow partially based on the steps you have shared. It should be publicly accessible as a Google Doc read only file below. My workflow involves moving in between Rhino and Revit so I also discuss how to Geo-Sync those two files so imports and exports snap directly into place. I also outline how to find Google satellite imagery. I'm not an expert in any of this but I did troubleshoot a few things from Andrew's video and discuss what I learned with respect to an importing error message in Revit, finding the right CRS in qGIS, dealing with large files ... others. Thanks again and good luck! Importing qGIS data: th-cam.com/video/ETngbGFwup8/w-d-xo.html Workflow Checklist: docs.google.com/document/d/1zUOxv3PuTl_5x8XqEEBd6d1pPxBrucr5IFmeVYbb1wE/edit?usp=sharing

Excellent contribution God Bless!
I am really enjoying this video, I am new in using Qgis but your step by step explanation is nice
Thanks for the comment.
Very Nice Sir
Hi Sir, well explained. I have one question, can we upload orthophotos in Google Earth or we can make Ortho kml
Thanks, it's very useful.
Can you tell is there any way to get the previous years Google satellite image in Qgis.
Is there any option or plugin to choose date also?

Hi Mauro. Thanks for your comment. I am not sure what you mean with "digitize vectors". Have a great day
Hi!! Can't we download image for bigger area using this method?
interesting.. thanks.. i learned!
Thank you. Very helpful.

Thanks ;)
thank you mister for this tutorial video
I have an error during running. How to fix this? Error creating GDAL output layer
Execution failed after 0.13 seconds
Im using 3.24
I am sorry but I have no idea about how to fix the error.
So helpful, thank you. You gain a sub.
Thanks for the comment. :)
Very very very very very nice😘😘😘😘😘
Thanks for the comment :)
so how accurate is this as compared to paid surveyor?
Hi Jerkins. This is a really good question. It depends on the resolution of the google earth satellite image. In some areas we have a really good resolution but in other ares the resolution is not that good. However, google does not tell us what is the resolution of the image.

There is no 30 U under the wgs 84 ?
Oh ive got it it’s 30 N
you got it!!!
@@GeoRGBCommunity thank you so much I’m working along with your videos to create the full map as I have an interview where I need to show how to use this software and what you are providing is excellent thank you I may need your help please be on standby thank you again your amazing 🙂
@@rafathchowdury1968 If you are following my videos you will get the job!! for sure!!! hahaha. Good luck
Thank you!!!!
My pleasure!
can this work in offline?
Hi GR33N TauRu. Once you complete all the process and you have the final image, you don't longer need internet connection. Then, you will be able to use the image offline.
@@GeoRGBCommunity okay thank you sir..
After running, it is showing error. What to do?

Hi Henry Rose. Thank you for the positive comment and for sharing the interesting links. Great work!
Output layer is blank
It's very weird, try it again. I am not sure what could be wrong. Maybe bad internet connetion.
Error
Iuuu
