ESRI World File Interpretation dialog box

The ESRI World File Interpretation dialog box is used to choose whether or not to position a raster image in a scene using an associated ESRI world file.

The dialog box is displayed automatically when you import a raster image and Echoview identifies an associated ESRI world file. Echoview will only identify an ESRI world file if it has the same name as the raster image and is stored in the same folder as the raster image.

Settings
