Trajectory formats
Trajectory formats category defines formats for importing trajectory information from text files. The format definition determines the order of the attributes that are stored in the text file, the delimiter that separates attribute fields, and possibly a character which marks comment lines.
A new format can be defined by using the Add button in the TerraPhoto Settings dialog. An existing format is modified by selecting the format and using the Edit button. A data click on the Delete button deletes a selected format.
You can load an example text file by using the Load example command from the File pulldown menu. With the commands from the View pulldown menu the dialog can be re-sized to enable the import of text files with 8 fields, 10 fields, or 15 fields.
