How to reconstruct a world file from a raster image?

If you want to create a georeference "world" file from a precisely positioned raster image (picture, map) in your AutoCAD drawing, you can use the auxiliar command WORLDOUT from the "CADstudio GeoRefImg" LISP utility.

After you select a raster image (bitmap), this command automatically exports the relevant world file containing the georeference (TFW, PGW, GFW, JGW, EWW...) in the image file folder.

WorldOut works also in Map and Civil but do not use the image repositioning command from GeoRefImg.vlx there.

You can download the free GeoRefImg from www.cadstudio.cz/download
