Identifying Mosaicked Images
When an XTF file is mosaicked in Isis, several files are generated:
• Filename.DDS_VIF. This is the mosaicked imagery and can be
imported directly into Del_phMap.
• Filename_track.DDS_VLB
• Filename_track.DDS_VOB
• Filename_track.DDS_VTX
These are vector files that are created from the sensor’s navigation
information. When imported into DelphMap a trackline is drawn with the file
name as a label.
When multiple image layers are inserted into DelphMap, it can sometimes
become difficult to identify the individual mosaicked layers. One way to help
identify the layers is to insert the associated “track” files with their labels,
essentially labeling each mosaic. The tracklines are inserted as a vector
layer and the user can select to have the layer name default to the file name
or choose a different name.
Viewing Layers
To view a layer means to display just that layer, apart from any other layers
that may be present in the Main Display Window. This makes the position of
features in any given layer more apparent by simple visual inspection. You
can create a maximum of four View Layer windows. The image in the Main
Display Window is not affected by this function.
To view a single layer apart from other layers
• In the Project Files Window, double-left-click a layer name.
The system opens a small, resizable window displaying just this layer. If the
white cross cursor has been enabled, any cursor movement done in the
Main Display Window is visually synchronized with the images in the View
Layer windows. The echoed cursor movement is a good way to quickly
determine whether some feature appearing in the Main Display Window also
appears in a given layer, since you can place your cursor on a feature
appearing in the Main Display Window and then see if the feature also
appears in the independently viewed layer. The number of separate
windows that can be opened is limited to four.
