Image (Bitmap) Import Options Dialog

The Import Options dialog allows you to specify options which determine how information in the file is imported. The Import Optionsdialog does not appear by default. If the file you have selected contains more than one image in bitmap form, then indicate which image (1,2,3,...) you want imported.

Spatial Reference Information

Some applications associate spatial reference information (such as projection, datum, and georeference parameters) with images representing a region of the Earth’s surface. Most image file storage formats don’t have a way to store the spatial reference information in the same file as the image. For these formats, the only way the spatial reference information can be stored is in a separate file. One image storage format, GeoTIFF (Geographic Tagged Image File Format), allows the spatial reference information to be stored in one file, along with the image.

Some (but not all) Golden Software applications can utilize the additional spatial reference information associated with an image file. If the program you’re running is one that can, and one or more sources of spatial reference information are available for the image file you are importing, a Spatial Reference Source list box will be displayed, allowing you to choose the source to use. Recognized sources of spatial information include:(None)

Choose this option if you don’t want any spatial reference information to be passed to the program, even if it’s available.

Embedded GeoTIFF Parameters

This option is only available if you have chosen an image file that is in TIFF (Tagged Image File Format). If you have and this option is chosen, the spatial reference information will be extracted from GeoTIFF tags embedded within the file. GeoTIFF is a vendor-independent format that can be generated by a variety of geographic software packages.

Golden Software Reference File

Golden Software supports a text-based format for storing spatial reference information in a separate file.

Blue Marble .RSF File

Blue Marble Geographics supports a text-based format for storing georeference information only in a separate file.
