1 PRINCIPLE
NaviPac Ukooa Exporter exports NaviPac data in P2/94 format. This requires some
manual definition of header files, as some information has to be entered by the
operator and some can be fetched from the NaviPac set-up database gensetup.db.
The module is designed as an application running alongside NaviPac:
The program is divided into two parts a header import/editor part and a data converter
part.
2 HEADER EDITOR
Some header data can be generated on basis of the NaviPac setup (saved in
gensetup.db) but others have to be defined manually by the operator.
To make this as easy as possible for the operator the program allows individual import
and editing for each header group.
H00 General Definition
o H0000 taken from survey file name
o H0008 taken from survey file
o Rest manually specified
H01 Geodetic Definitions
o H0100 and H0101 manually specified
o Rest taken from set-up file
H02 Survey Definitions

2.1 Header view
The one and only view in the UkooaExp is a textbased header view, intended to hold
and display the header part of the ukooa export file. This view can also be used for the
data part, as they can be appended to the view while exporting, and it can be used for
opening and viewing of other ukooa files, as well as text based files in general.

The header can be freely modified by the user when inside the view, so it is the user
responsibility to leave it into the right format, but a Format helper dialog and format
help on the status bar, makes inspection and format easier. This format help conforms
to the ukooa P294 specification, as it is taken directly from the original document.
The status bar displays the actual field that the cursor is within, the size and limits of
that field, and the datatype and the description for that field.
The same help is found in the Format helper dialog, which is invoked on the current
cursor line by clicking the on the toolbar or by holding down CTRL when clicking
on the line to inspect.
2.2 NaviPac based header setup
Insert all or part of the np setup into the header view by selecting in menu list.
Anywhere in the headerview additional items can be inserted, by positioning the
cursor somewhere at an existing line. If cursor is placed at the first colon (char) of a
line, insertion will happen before that line, else it will happen after that line.
Then select Head Insert\Navipac Setup\some group and that group is converted from
the NaviPac db to the view.

All header data can be inspected after insertion and eventual manual completed, line
by line for data content and conformation with the format rules.
The entries inserted at each command will be sorted after header id, within the group
related to that command.
Data from set-up are formatted as specified, unless some information must be user
specified, and marked with a ‘?’.
Lines ending with ‘?’ does not have the appropriate length of 80 chars and must be
completed by the user.
2.3 Manual header setup
Manual defined data can be guided from a menu, to an appropriate format.
Anywhere in the headerview additional items can be inserted, by positioning the
cursor somewhere at an existing line. If cursor is placed at the first colon (char) of a
line, insertion will happen before that line, else it will happen after that line.
Manual Item brings up a list of header items to select.

Clicking an item and pressing the Fill & Insert button brings up the Format helper
dialog (se above), for formatting the particular item, and afterwards insertion in the
header view. The Insert definition button just inserts the line selected in the header
view.
Lines edited by the Format helper dialog do have the fixed length of 80 chars.
It is the users responsibility to ensure correct length and correct format on lines
formatted/edited without the Format helper dialog, as it is possibly to edit (and corrupt)
all lines freely, direct in the view, as well as it is possibly to import other header files,
and to copy, cut and paste direct in the view.
2.3.1 Comments
Comment can be inserted anywhere in the header by selecting a line (clicking it) and
pressing
. Then at the following line “C001 “ will be inserted, and comment must be written
direct in the view, and should have length 80 (append spaces to reach 80). User must
modify type if other than C001 is needed. Ukooa have these rules for comments:

Additional Comments
Three comment records are available for general, free text comments, considered
relevant to the survey.
C0001 - for information related to the entire project;
C0002 - for information related to the seismic line only;
C0003 - for information related to (inter-)event data.
Any number of these records may be inserted in the data. C0001 and C0002 records
may appear anywhere among the other header records, but after record H00@9.
3 DATA EXPORT
3.1 Settings
There are a series of settings that the operator must be aware of prior to using the
exporter. Please note that this also applies to the header definition.

Static Header
The static header file is a tool that allows you to enter static text information that will
replace unknown messages in the header. The software will search in all headers after ?
(things NaviPac don’t know) and look it up in the INI file. The file must be defined
like:
[StaticHeaders]
H1500-7=0.5556
H1500-40=Some text
H1621-9=1234
H0001-19=APJ TEST

The first part identifies the header number (eg H1500) and the second part defines the
starting character (eg -7).
Example:
H1621-9=1234
Will modify the line H1621 2 ???? 00000.0 00000.0 0000.0 00.00 00.00 00.00 1500.00 1500.00 0 00000000
To
H1621 2 1234 00000.0 00000.0 0000.0 00.00 00.00 00.00 1500.00 1500.00 0 00000000
Note: The static information will not be activated until you enable the menu Export, Parse static
headers
Runline
You may select reference to used runline file. The information will be used to
generate the header data.
Reference: H0008 & H0009
Sound velocity profile
You may select reference to used sound file. The information will be used to generate
the header data.
Reference: H1500 & H1501
Setup file
The UKOOA exporter is very dependent of the match between the selected files and
the NaviPac setup. As default the exporter uses the setup in the default NaviPac
database (\eiva\navipac\db\gensetup.db) – but you may overrule this by selecting
another file.
Data files
Select the NaviPac data files to be converted to ukooa data. You may remove a file by
selecting it and pressing remove.
Vessel Id
The Applied Vessel ID inserted here is used as base both for header insertion and data
export, and cannot be changed within an export.

Secondary Vessel
The UKOOA exporter may add secondary vessel information to the file. This goes a.o.
for a towed seismic operation where the towfish represents the secondary vessel. In
that case you must enter the NaviPac object number and the vessel Id to use in the
output file
Inter event data
Inter-event data of type T (if any in the NaviPac data) can be included in the export by
selecting here.
Display data
Append exported data to headerview, writes the data to the header view while
exporting, visualizing the data export, but also slowing down the export, therefore a
progress bar will appear under export.
3.2 Run exporter
Clicking or the menu Export\Run exporter starts the export, by first bringing up
the export settings dialog, and the prompting for export file name and path.
File name is automatically suggested as NaviPac data file name + .UkooaP294.txt.
3.3 Data Format
The operator must specify if the exporter should handle event-only (default) or events
and inter events data.
Events are recorded in E records and inter events in T records
3.3.1 Event records
Includes one total data series for each generated event (shot-point)
E1…. Vessel related data
E1000 General event data
Line name, event number, date and time. Seismic identifier left blank
E12@0 Positioning data
Position of all relevant objects
E14@0 Echosounder data
E16@0 USBL Data
