Georeferencing Historical Aerial Photography in ArcGIS 10.1 

Actually the corner of buildings will be less accurate. Objects that extrude from the surface will appear slanted, this is due to the angle of the line of sight between the object and lens. Things close to the surface of the Earth are the best, because their positions will not be distorted. The further from the lens the more distorted the image. Sometimes the building will slant one way in one image and another in a different, introducing even more error. All depends where the lens was.

Hi. I just dicovere this and that could be something I was looking for. I have a question tho. My georeferencing files is TFxw. I am using ArcGIs 10.8. Is that what I should expect?

how did they take Orthophotos of entire cities 100 years ago in high resolution and perfectly fkat. what cameras did they use in aircraft? really cool

How I rectify a aerial photography without calibration parameters? I try with DEM using UTM but without successful :(

Huge help on my assignment where I had to georeference an historic 1933 photo. Thank you!

This is really helpful. I'm so lost in my GIS class :-)

Jpeg should work just fine. ArcMap can support jpeg, sid, tiff, img, and other formats. The georeferencing will generate a jgw file with a jpeg, as opposed to the sdw file generated here.

Yeah, I bushed over it because I am not a big fan of the scale tool. I prefer to use the "Fit to Display" and then use the pan tool to place the photo in place. The scale tool basically allows you to shrink or expand the image. It is a little clunky to use and can slow you down. What is better is to know the scale the image was before scanning, and then manual type the scale into the display scale, and then do fit to display. So for example if you have a 1:24k image just set the scale to 24k

Hi there. this video is great. What file format does the new imagine need to be in? I tried jpeg but it doesnt accept it. Thanks

Great video!! However you only brushed over the scale tool. Do you know how to use this? I am currently trying to georeference two rasters that are very different sizes and cannot get it to work. Thanks!

Also I like intersections because over time roads may get winding as cities grow, but the middles are typically the same. Good way to find two points.

Is there a reason for not using vertices, like corners of buildings, and using road intersections instead (which are much less accurate)?

Is the video link broken? All I'm seeing is the circular arrow going round and round.

The best explained georeferencing I have seen. thanks for the video!

Cheers man this was great tutorial. THUMPS UP

You Sir are a legend, this video helped me out so much with my assignment for university. THANK YOU SO MUCH MATE!!!!!!

Also, this is a digression but wanted to know, which software have you used to capture this video?

I used Camtasia from TechSmith. It is a pretty nice software package.

The power of youtube is better than words sometimes. Great video!

Wow this was really interesting!! Thanks for putting this together!

Thanks So much for your video. It really helped me .. :)

Right angle me building jaldi kaise bnaye videos bnaiye

Great video. Thanks, it helped me out tremendously.

Cool voice. Sounds like a radio show.

Thanks! Will keep this in mind the next time I georefrence.

Glad I was able to help!

Wonderful tutorial!

Glad to help

Very nice presentation. . . .

Thanks

This was very well done! I am not a GIS tech and could follow along easily!

This was very helpful, thanks!
