I am a GIS specialist for the Department of Interior, and this is a fantastic video to explain georeferencing. I learned it in school, but I refer back to this video from time to time.
I am a former Cartographer who used to use ArcMap, but have just got back into GIS and have to learn ArcPro - this has been very helpful as my first task is to georeference several scans of old paper maps. Great easy instructions and well explained.
Thanks! This is just what I was looking for. I want to do the same for some old (1909 & 1926) maps to show how the original allotments to Suquamish tribal members changed hands to become the checkerboard reservation that it is today.
Hello question so I'm having issues with the xml File. I already added my control points and clicked save, and when I go to my project files and try to get my .jpg.aux.xml file I don't see it. I reopened Arcgis and tried to do it again. I still have the control point in place but I don't have the xml file. Do you have any advise ? Thank you
Lovely tutorial, thanks for the upload! I often have to use imperfect scans of maps (the map sheet is warped in the scanner), could you elaborate on how you would modify the above workflow in such a case? Just add lots more points, or is there another trick you can use? Also, probably important to mention that in the 2nd part of the video one doesn't need to match the projection and coordinate systems of the initial map, but can instead use whatever suits their project.
Hi, yes it would certainly help if you add more points distributed sufficiently across your map and use a higher order polynomial transformation which can allow the map to stretch and warp as required. And I agree, for the second method that I showed, it's not necessary to fix a specific coordinate reference system as you are no longer relying on the numbers (coordinates) stated on the map :)

Glad it was helpful! 🤠

Thanks 😊
Thank you very much. very clear and explicit video. I highly recommend.

You did great job bro. Thank you for your valuable information. 🥰
Thanks man! You're good at this

sooooooooo goooooooooooooood！very helpful！！！
Thanks very much, this video has helped me tremendously. Shane
You are welcome
Thanks. Your teachings are mind blowing, be it arcGIS, QGIS or ArcGIS Pro
Thank you

Very good video thank you
How do I know it is georeferenced correctly? Do I have to check RMSQ value? what is the tolerance?
Is there a way to create an exportable file compatible with Google Earth?
Great video, I have a pdf map with a polygon shape on it. Once I geo reference it in Arcpro, Is there a way I can save only the polygon shape?
Hi, what if i cant find a map with the coordination system stated?
Is the second method of matching points also available on QGIS?
Yes, absolutely. You can check out our 'How to georeference a map in QGIS' tutorial to check that out - ruclips.net/video/jKLBFddpTGI/видео.html
expecting a tutorial similar to arcmap for beginners with playlist
thanks for the tutorial! Could you share the image file so we can also do the exercise?
Yes, will add the image as a downloadable file in the description
