beforehand. The future work should include efforts for
performing those processes directly within ImageStation
software components.
Certain assumptions are made as to the naming conventions
used for the images and their associated support files. Two
methods are supported. First, the base name (less extension) of
the "info" file for a rectified image and ^psb" file for
orientation data are contained within the base name of the
image file (or vice versa). Second, the first N characters of the
image, info, psb, and optional parallax grid file to reduce y-
parallax are the same (where N is user-definable on the user-
interface). The system also requires the images be converted
into a Z/I Imaging-supported format such as TIFF before
importing into ImageStation Photogrammetric Manager. This
includes tiling, adding overviews, transposing, and converting
to TIFF format. The ImageStation software includes the
necessary utilities for converting the STARIMAGER raw
images.

Figure 6. Import STARIMAGER Images Dialog
Import Single STARIMAGER Image — Select this option if one
wants to import one image and create one photo. Selecting this
option toggles the three Folder fields to three File text fields
where one selects STARIMAGER Image File, INFO File,
optional Parallax Grid File (PGF), and PSB File.
Import Multiple STARIMAGER Images From Folder — Select
this option if one wants to import a folder of images with one
click. Multiple photos and models are created during the import.
Selecting this option toggles the three File fields to three Folder
text fields where one selects STARIMAGER Image Folder,
INFO Folder, optional PGF folder, and PSB Folder.
STARIMAGER Image Folder/File — This field toggles between
Folder and File based on the Input Selection option. When
toggled to folder, the user provides the input folder containing
the STARIMAGER Images. When toggled to file the user
provides the full file path (including the filename itself) of the
image to be imported.
INFO Image Folder/File — This field toggles between Folder
and File based on the Input Selection option. When toggled to
folder the user provides the input folder containing the
Orientation Information Files (INFO) of the images to be
imported. When toggled to file the user provides the full file
path (including the filename itself) of the associated INFO file
of the image to be imported.
Optional PGF Folder/File — This field enables when checked
and toggle between Folder and File based on the Input Selection
option. When toggled to folder the user provides the input
folder containing the Parallax Grid Files (PGF or in some cases
XYZ extensions) of the images to be imported. When toggled to
file the user provides the full file path (including the filename
itself) of the associated PGF file of the image to be imported.
PSB Image Folder/File — This field toggles between Folder and
File based on the Input Selection option. When toggled to folder
the user provides the input folder containing the
STARIMAGER PSB Support Files (PSB) of the images to be
imported. When toggled to file the user provides the full file
path (including the filename itself) of the associated PSB file of
the image to be imported.
File/Folder Browse Buttons — These buttons display a simple
common browse dialog that allows the user to browse the file
system for the desired file/folder depending on the Input
Selection.
File Extension Fields — These fields are enabled when
importing multiple STARIMAGER images from folders. These
extensions are used as filters when collecting the list of files in
the user-defined folders. This allows the user to have different
extensions for the image, INFO, PGF, and PSB files. This may
be useful if the user has renamed the files to use an extension of
their choice instead of the defaults delivered by STARLABO.
STARIMAGER Camera - This combo box is used to select the
desired camera from the available list of STARIMAGER
cameras in the project to associate with the photos created
during the import of the STARIMAGER Images. If none are
available and the user attempts to import images an error
message is displayed informing them to create an
STARIMAGER camera before attempting to import any images.
Create STARIMAGER Camera — Select this button to bring up
the Create STARIMAGER Camera dialog. A STARIMAGER
camera must be selected before importing images.
TSP Zone- This dropdown combo box allows the user to
specify the Tokyo State Plane zone number for the images
being imported. If the STARLABO project support file (PRJ)
file is available then the user can select the “Read Zone from
PRJ” button and let the application automatically determine the
zone number by reading it from the PRJ file.
Identifying Text — These fields allow the user to specify the text
string used to identify to which sensor an image belongs. For
each of the sensors the user can specify a sub-string that occurs
somewhere within the base name of the image file being
imported. For example, if the base name of an image file
contains the string * CHI" then it is interpreted as a Forward
sensor image. This information is then used to during model
creation to create the models selected by the user. This
information is also needed during the orientation process to
determine which orientation parameters from the
