How should i format appropriate .jgw file for this picture?
Best Answer
I don't see anything in that EXIF that could possibly provide enough information to construct a world file.
As Zoltan pointed out in the comments, you can might be able figure out the pixel size from geometry (given camera position in 3D, and altitude above ground), if you are willing to make the assumption that the camera is facing straight down (normal to the earth).
However unless you have some information about which direction is North in the image, you won't be able to determine the rotation of the image.
If that isn't obvious, consider taking two images from the same location, both with the camera facing straight down. One has the left edge of the camera facing North, the other has the camera "spun" about an axis that is normal to the earth's surface, such that the same left edge is now facing South.
Both images will look the same, except one will be "upside down". They'll have identical EXIF data (except for some time information - all the geospatial bits will be the same).
So you need more information than is extractable from EXIF.
