GPSeismic Release Notes

GPSeismic Version 2007.1 Release Notes

Highlights

1) Exclusion zone (XZO) files now support holes.  Extremely complex polygons
can now be used as exclusion zones.

2) Enhanced error reporting in GPSQL.

3) Added a QuikMap DEM function to create a shape polyline file of contours.

General

1) Added Military Time to the time formats in the modern spreadsheet viewer.

This was requested by Vince Hanrahan of CGGVeritas.

2) Corrected error in modern spreadsheet in which copying and pasting several
cells would erase the contents of some cells.

This was spotted by Michael Schlautmann of DMT.

3) In the ASCII Import dialog, when importing heights and transforming the 
horizontal coordinates, if the input and output units differ, the input 
heights will be scaled to match the output units.

4) Several programs (GPSQL, QuikCon, GPLocator and GPNav) could issue an error
during startup if the option to save toolbar settings was on. This has been fixed.

This was spotted by Alan Quartermain.

QuikMap

1) Fixed an ESRI ASCII DEM mirror image problem.

This was spotted by Glyn Barnes of WesternGeco.

2) Added a DEM function to blank a DEM using an XZO file. This can be used to 
eliminate unwanted or sparsely populated portions of a DEM.

This was requested by Glyn Barnes of WesternGeco.

3) Added a polygon capture option to compute bounding polygons of point regions 
and send these to both shape and XZO. There is a video on our web site that shows
how this can be used:

ftp://ftp.gpseismic.com/videos/quikmap_polygons_around_point_patterns.exe

This was requested by Glyn Barnes of WesternGeco.

4) When performing a dynamic polygonal search on a raster image, a window 
showing the computed area of the selected color region will be displayed.

5)Added a DEM function to create a shape polyline file of contours from a DEM.
This very cool capability requires that the user select that function on the 
DEM dialog, then select both an input DEM and an output SHP file. The user also
enters the contour interval or, if left at zero, the program automatically
determines a reasonable interval.  The resulting SHP file has an underlying
database that contains the contour value so programs like GPArc will be able
to render labels and special 'class breaks' colors.

This was requested by Glyn Barnes of WesternGeco.

6) QuikMap XZO files now support holes. When creating a polygon dynamically, look
for an additional check box on the dialog that indicates if the polygon about to be 
drawn is a hole. If you visualize a donut, the center would be a hole and inside 
the hole is outside the exclusion zone. With the advent of holes, XZO files
are more in line with the capabilities of polygon SHP files.

Project Manager

1) In the Utility menu, there is a new utility called Geoid Extents which will
prompt for a geoid model and then graphically show the extents of the model on
a world map. You can also click on the map and determine a geoid height at that
point. You can also open a second model and see what the geoid height is for
both.

2) When creating a project, you can now specify up to 10 user fields. Field
name, type and where applicable, size, are all entered by the user. All settings
are remembered for subsequent project creation sessions.

This was requested by Alan Stanton of WesternGeco.

QuikLoad

1) Those pesky Canadians. Apparently, there's a new seismic pattern in town. 
Think a brick pattern, but the first two racks share the same odd number track,
the next two share the next odd track number, etc. So now in the 3D pattern
preplot builder, there is a Preference menu with one item. If its checked, 
you'll be hit with a prompt to preserve odd or even tracks. In the particular 
case of the first track being odd, you would want to preserve odd so you
would say YES. To keep it simple, the routine simply detects (in this case) 
even lines and subtracts one from the track. So we would have

Track 1 - no change
Track 2 - becomes 1
Track 3 - no change
Track 4 - becomes 3
Track 5 - no change
...and continuing....
 
2) The rectangular capture tool now allows the user to refine with SQL just 
like the polygon capture method.

This was requested by Khalid Ali of WesternGeco.

QuikView

1) Added the ability to save and retrieve the data from the Zupt user interface
spreadsheet. This will allow the user to edit a file, but completely process
the file at a later time.

This was requested by Mark Bush of GLS Surveys.

2) Multiple rover antenna types for System 1200 are now reported correctly.
Previously, antenna heights were accurate and reported correctly, but the 
antenna type remained the same.

This was requested by Paul Pink of WesternGeco.

3) QuikView now retrieves the Topcon TopSurv receiver S/N.

This was requested by Brian Marsh.

GPSQL

1) Added ability to make Google Earth KML files without having Google Earth
installed. The new utility works with a query and can be found in the
Utilities menu. Note that to decrease the size of the files, multi-geometry
files are made.

This was requested by Jan Quaak of CGGVeritas.

2) Added ability to read Google Earth KML point files and import into a table.
Neither multi-geometry, line or polygon types are supported. This new utility
is located in the Import menu.

This was requested by Glyn Barnes of WesternGeco.

3) In the Duplicates Manager, there is a new File menu item which will provide
a summary of all duplicates. This includes the number only unless there is
a sweeps field. If so, the summary contains station, number of total points,
number of unique sweeps and time span in seconds of all sweeps.

This was requested by Brian Marsh.

4) When creating a graphical query using QuikMap, the resulting Mapping table
now contains two station fields (text and value). Therefore, if you originally
use the Station (text) field for the data sent to QuikMap, the resulting stations
of the Mapping table will be identical to what you see in the Postplot or Preplot
tables.

This was requested by Alan Stanton of WesternGeco.

5) The 'change field size' routine failed if the field name had spaces. This has
been fixed. Also, its now possible to reduce the field size with this. Previously,
you could only make the field larger.

6) Added a new error handling dialog that allows the user to copy the error
message so it can be pasted in an e-mail. An error number is now evaluated so
as to try to give more information to the user. For example error 3021 would
previously report 'no current record'. Now it states that 'there are no records
in your query.' There is a new Miscellaneous Setting item for enabling text to 
speech. Turn this on and errors and some general messages will be spoken (and
the text will be displayed in a dialog) if you have the Text-To-Speech libraries
installed. If you have XP or later OS, you probably have it. You can test this
by going to Control Panel and selecting 'Speech'. Extra voices can be obtained
by going to the link below and downloading/installing the Sp5TTIntXP.exe file:

7) Added ability to import Opus Files. The table structure consist of station,
latitude, longitude and ellipsoid height. As with most imports, you can add to 
an existing table or create a new one. A prompt for NAD83 or ITRF coordinates
is made. Note that the Opus format is very unstructured and as such, the import
mechanism might not always work. The key elements are the lines shown here:

LAT:   34 13 25.72231      0.011(m)        34 13 25.74226      0.011(m)
    W LON:   96 55 28.48032      0.005(m)        96 55 28.51394      0.005(m)
   EL HGT:          186.460(m)   0.024(m)               185.289(m)   0.024(m)

Its expected that the lines exist and are formatted shown.

This was requested by Les Merriam of STI.

GPLocator

1) Log files can now be converted to SHP point types as well as lines. You will be 
prompted for which to create when you select the 'Convert Log File To SHP File'
item from the File menu.

This was requested by Kevin Crozier of PGS Onshore.

QuikCon/ConQuest

1) Added two import routines to the DCO editor for Nikon. The menu items
are called 'Nikon_T' and 'Nikon (Wittig)'. See the QuikCon help file for a 
description of these formats.
