Are you just getting started with #GIS and #QGIS? This online course will teach you the basics and then you can come back to the #burdGIS channel to improve your skills! :) www.udemy.com/course/an-introduction-to-gis-and-qgis/?referralCode=E39701D884A9EB2B5831
This has to be one of the absolute best software tutorials on TH-cam. Seriously! Perfectly clear instructions easy to follow speed and no bullshit ass music.
I have been working with GIS a lot longer than you, but being retired I still find reasons to create maps and do spatial analysis. I am learning new systems as I have never liked ESRI’s tactics. I do have an active Global Mapper license and need to digitize a very old trail across the Appalachian High Plateau that only exists on an ungeoreferenced image. It looks from your video like QGIS has the superior georeferencing system. Thanks!
Well, despite my initial trepidation, it all turned out to be rather simple after watching and then pacing my efforts with your very clear instructions. Thank you.
Very good quick run through, I don't know much about QGIS but I was able to understand most of what was being explained, looking forward to doing some georeferencing myself soon.
Thank you so much! I was getting so frustrated when my modified map would turn out all warped, but I followed your amazingly clear and great tutorial, and I got it!
Thanks for introducing me to this software. I have this software installed in my PC from 7-8 yrs but not practicing it. now you inspired me to use this. I will defiantly introduce this to my Msc evn science students. looking forward to contact with you through ur channel. Thanks.
Thank you for sharing, this was a great explanation! How do you inverse the georeferencing process? Distort the modern map to match the undistorted antique map.
Interesting idea. Assuming the antique map is already georeffed the you could output the modern map as an image (jpeg or PNG) and bring it in to be georeffed using the antique map as reference
@@burdGIS thank you for your reply, I will give it a shot. Was hoping I could somehow use the .points data that was created when georeferencing the antique map. I will need to output the elevation map, and features are challenging to match to the antique map.
Great video and very clear. What is the best approach when you've got layers with different CRS's like WGS84 for Google underlay and then UK LIDAR data using OSGB1936? The georeferencing is then way off? Sorry if I'm asking a daft question but I'm fairly new to this.
Thanks for the question. In this scenario which layer is being georeferenced? It sounds like both have a CRS. If, however, you're aiming to georef a layer that does not have a CRS then I would always set my PROJECT CRS to the desired CRS. Any other layers required in the project I would REPROJECT to the desired CRS. If using a basemap the setting of the project CRS should project them on the fly but I'd be tempted to use some OSGB36 base layers (check out the Ordnance Survey's free offerings) to use as reference. I hope that helps and please feel free to get in touch via email (www.burdgis.com/contact) if you have any questions.
Thanks for supporting the channel Dhaval! You could use something like map tiler (www.maptiler.com/) to build your own basemap using a georeffed image. If you'd like a video on how to do this please let me know.
When you add the layer to be georeferenced it sometimes won't show. You have to fit to display. Also make sure to double check layer order in the layers panel
Thanks for this. I have a rectangular .png file that I want to convert to a raster image. I also have a .kml file which has the bounding coordinates (north, south, east and west) of the .png. I want to georeference this onto an open map. base layer. Any thoughts on this?
@@burdGIS Hi Oliver, the .kml came from an application called ve2dbe which is a coverage modeller for radio systems. You enter an aerial point and the radio characteristics and it shows the coverage using a topology map. We're part of a DCMS funded project looking at mobile not spots near Salisbury and I wanted to take a number of these coverage plots and add them as layers to QGIS. Would it be easier for me to contact you directly by email?

Thanks for the video. If I wanted to georeference a Bing Maps map and align it with British National Grid coordinates would I change the 'Target SRS' to British National Grid in the Transformation Settings?
Hi Patrick. Yes, that should work. It may be easier to bring in Bing imagery as a tile layer and then set the project CRS to EPSG 27700. This was QGIS will reproject the tile layer on the fly. Take a look at my xyz tile layer video for more info: th-cam.com/video/2vsM-ccd44o/w-d-xo.html And let me know how you get on.

Hi, thank you for this vid. I georeferenced my first image to this.... and will keep practicing. This was very helpful, thank you!
Great to hear it was useful Rodrigo 😀

Great to hear you had no problem with this Mel. Please feel free to share the video. A full course is a happy course :)

Thanks for your kind words Lenora! Please feel free to share the video 😀
you are a very good teacher. Happy new year!
i still watching your videos and help me a lot :)
Very kind of you SS Soha :) Happy New Year to you too.

Very useful Thanks a lot
You are welcome
Many thanks for this tutorial, I couldnt find the tutorial for the XYZ

Very nice video. But how do we get these maps under xyz tiles?

great video thank you. do you know if theres a work around when the jpeg you are trying to geo reference layer isnt displayed on you source map.

hello pal, when i click the green start button for the second time the whole program stops responding, how do i fix this ?
What version are you using? And are any error messages shown or does it just freeze and crash?
@@burdGIS never mind now. I woke up this morning and gave it another go and it works now.
