Although pictures in JPG format do not have coordinate information, they can still be opened in ArcMap and can be directly dragged in, as shown in the following figure:
There is a function in ArcMap called "rolling shutter", as the name implies, just like a rolling door, when there are multiple When layering, one side of the rolling door displays the information of one layer, and the other side of the rolling door displays the information of another layer. It feels a bit like a perspective eye. In addition, there is a beauty that is difficult to trace. .
According to this principle, if we find photos of a place with the same angle of view during day and night, and then stack them together, the upper part shows the day and the lower part shows the night, it seems that there will be a kind of time and space disorder, love and hate entanglement. The strange feeling.
I found such a picture on the Internet, with daytime on the left and night on the right.
Save the screenshots of the left and right parts separately, and then drag them into ArcMap.
Then call the rolling tool, the specific steps are as follows:
1. Click Window in the main menu, and then click Image Analysis.
2. Click the raster layer in the image analysis window.
3. Click the Swipe layer button to roll the layer
Finally, drag with the mouse to see the effect.
