STARIMAGER camera to be used when computing image-to-
ground and ground-to-image coordinates.
Project Coordinate System/Define — This field shows the
currently defined project coordinate system. The user has the
ability to change the project coordinate system by clicking the
Define button. This is the same project coordinate system
definition dialog that is available in the Edit Project command.
This field is provided here as a convenience/reminder to the
user in case they forgot to define a valid mapping coordinate
system when they created the project. The default coordinate
system of "Rectangular Grid" is invalid for the project when
importing STARIMAGER images. This is because there must
be a valid transformation between the EO defined in the INFO
file and the Project Mapping Coordinate System. There is no
transformation between Rectangular Grid and any “Mapping”
coordinate system. If the user attempts to import images when
the current Project Coordinate System is set to “Rectangular
Grid” an error message will be displayed.
Model Creation Options — These checkboxes are used to select
which models are created during the import of the
STARIMAGER Images. The STARIMAGER has three sensors
(Forward, Nadir and Backward). The software allows the user
to differentiate the three sensors from the same strip using an
embedded string. This string is user-defined in the text fields
provided to the right of the Model checkboxes. After photos
have been imported, the list is examined again. As each photo is
examined, the user-defined string for say, Backward
(_CH3/_ch3, case is insignificant), is searched for in the image
file basename. If found it is assumed that this is a Backward
image. If the checkbox is selected for Backward/Forward model
creation, the CH3 is replaced with CHI (user-defined text for
Forward images) and the list is searched for a photo whose
image file matches the Forward name created with the replaced
CHI. If found these two photos are used to create a model.
The model name uses the naming
LeftPhotoID+RightPhotoID (since strip Ids are not defined for
the import they are not used in the model names). The same
string replacement and search is used for the remainder of the
photos for creating the other checked model types until all
scenarios are covered.
Overwrite Options — Select these checkboxes to allow the
software to overwrite any existing photos or models when re-
importing images. Unselecting will cause the command to skip
any pre-existing photos it attempts to create during the import.
Processing Information — This information area echoes statistics
and processing status for each photo and model that is created
during the import. This area will contain any problems or
warnings that occur during the import as well as successful
reporting for each photo/model.
Processing Report... - This button allows the user to save the
Processing Information to an ASCII text file. Selecting this
button brings up the common browse dialog allowing the user
to specify the location and filename to be saved.
Photos and Models... - This button brings up the Photos and
Models dialog. This dialog is used to View and Delete existing
photos and models.
Import Images — This button initiates the Import process using
the user-defined parameters. Any status messages are reported
in the Processing Information field. Also, a percent complete
convention of
bar is displayed at the bottom of the dialog. A valid project
mapping coordinate system must be defined prior to the import
as well as an active STARIMAGER camera.

Camera ID — This field is used to define the name of the new
STARIMAGER camera to create. As with any valid camera ID,
no spaces or special characters are allowed.
STARIMAGER Camera Calibration Files - Use these fields to
specify the full path to the three calibration files associated with
STARIMAGER camera. All three files must be specified before
creating the new camera.
Available Cameras — Informational list of available cameras
defined for the project.
Create STARIMAGER Camera — Select this button to create
the new camera. All calibration files must exist and a valid
camera ID must be specified.
Figure 8 is the dialog for photos and models. The following
describes items on the dialog:
Photos List — This list contains the available photos in the
project. It allows multi-select to facilitate the deletion of photos
when the Delete Selected Photos button is used.
Delete Selected Photos — Use this button to delete the photos
that are currently selected in the Photo List. Any models that
reference a deleted photo will be deleted as well.
Models List — This list contains the available models in the
project. It allows multi-select to facilitate the deletion of models
when the Delete Selected Models button is used.
Delete Selected Models — Use this button to delete the Models
that are currently selected in the Model List.
Refresh Status — This button is used to populate the Status
column on the Photo list. The initial display of this dialog has *-
-—--—- * for the Status column for performance purposes. If the
