This is accomplished by adding the REPROJECT tag to the file. This tag is used in place of the coordinate unit definition and causes the file reader to look at the end of the file for a block of text describing the projection definitions. The definitions are a series of flags that listed below. NOTE: GMF files do not need the REPROJECT tag, the projection definitions can occur in a continuous block anywhere in the file.Hugoen-us
