Image insert of non uniform X Y SCALE Raster

Hi,

I am Working with AutoCAD MAP 2002

I Insert a Raster file ((JPG) who was rubber sheet to it's coordinate By Raster Design method and was export by raster design tools with burn rotation and world file) By Map>Image >Insert
The raster's was out of place by 800 meters
The JGW has a non uniform X Y Scale.

I need that the raster's will be insert in it place in AutoCAD Map 2002. as the same place it is in the Raster Design.

Do the methods of INSERT in ACMAP 2002 is different from ACMAP 2002 Raster Design and what are the differences in the Calculation?

Dose the Size of the area in raster influence on the INSERT Method?

Thanks

Dana

Map doesn't know how to Rubber Sheet. Inserting a differential X-Y
image in Map will be different than inserting that same image with
Raster Design.

Map knows how to rubber sheet.

but the raster I work with has been rubbersheet and export from Raster design.

Map knows how to move the corners of the image, Raster Design knows
how to move the pixels, modifying the image. That is different.

check your units in the drawing. with large images that cover a lot of area your units need to be set to the highest possible angular precision to. i've brought images in with the units at their default values and have notices a large shift in the position of the image.
