  • GPSeismic Version 2017.0
GPSeismic Version 2017.0 Release Notes
1) The geodetic library has been modified to utilize GSB shift files in which coordinates
are defined in degrees. The majority of shift files, including the Canadian NTV2 file, have
coordinates that are defined in arc seconds.
Requested by Jan Quaak of CGG.
1) The Trimble Imagery preview mechanism has been overhauled and there are now
four available imagery feeds to choose from. For previews, there is now a navigable map
of your area that depicts the high resolution imagery you would receive if you place an order.
Any one of four imagery feeds can be turned on or off. Additional layers depict the age of the
imagery. See this link for a document on how to use this utility.
2) The Trimble Elevation service utility has replaced the SRTM DEM utility. The
SRTM DEM utility originally allowed the user to download and convert SRTM areas
that were one degree by one degree in size. Now, you can get elevations that are defined
by a shape polygon file in local grid coordinates and the elevation data can be SRTM or NED.
SRTM stands for Shuttle Radar Topography Mission and has 30 meter spacing resolution
worldwide. The National Elevation Dataset (NED) is the primary elevation data product of the
USGS. NED data is available nationally at resolutions of 10 meters and in limited areas
1 meter. More elevation datasets will be added when available. See this link for a document
on how to use this utility.
3) The "Add new layer" button in the Layers dialog now allows for selecting multiple images.
Also can now open multiple files via Drag/Drop and recent file list will reflect this.
4) In the shape toolbox, when shape files are transformed or translated the new SHX file's
header is now updated with the same bounding box as the SHP file.
5) The SNS configuration utility now has the ability to convert OBJ Wavefront files to GRD.
 This capability is accessible when adding a DEM to an exchange database or from the
SNS menu. the SNS menu also includes a new item which will convert a surface model in
DXF format to a GPSeismic GRD digital elevation model.
6) Added sexigesimal to available formats in the Report Builder.
7) You can now drag rows to different locations in the MAP table viewer of the SNS utility.
8) You can now enter a name for the DXF layer when converting a line or polygon shape file
to a DXF line file.
Requested by Marin Mocanescu of Argas.
9) Added a utility to convert a local geoid model in GRD format to the Trimble GGF format
for use in TBC, Trimble SNS, and other applications.  This can be found in the Tools menu
of DEM Conversions.
Requested by Andrew Bowes of Saudi Aramco.
1) Trimble SSF files are now included in the Specific ASCII import list. The SSF format is binary.
Current implementation does not support feature offset but simple offset parameters (horizontal
distance, slope distance, azimuth and inclination) are preserved as an attribute. If the slope
distance is zero, the offset attribute reflects 'none'. Complex offsets are noted as 'complex offset'. 
User can elect to average point features. When point features are averaged, the number averaged
is given in the comment field. Note that Survey Mode Text will always reflect Unknown status.
The real time source as indicated in the file will always be noted in Comment field. This can be
'beacon', 'single base', 'WAAS', 'Landstar', 'Omnistar', 'LAN' or "unknown'. Positions are computed
by adding recorded deltas to the virtual reference coordinates in file header. No other correction
is applied.  Up to eleven attributes are preserved for features.
1) If you have just created a new database, you can now import an ASCII coordinate file into it
and specify 'PREPLOT' as the table name. When you do this, the structure of the new table
will be the standard 'PREPLOT' table structure. If you import an ASCII coordinate file and
want to append to an existing PREPLOT table, it will do that as well. This new capability is 
primarily for SNS users who have GPSQL/QuikMap and want to specify a GPSeismic database
for point navigation.
2) Added the ability to append backup SNS log records to an existing SNS log table. Backup logs
can be those exported by the user of System log files.
3) All field types on the main user interface are now displayed as true SQLite field types. This
is a display item only and does not affect any other functionality.
4) There is a new utility that can be used with SNS log files. The utility can be used to determine
SNS LOG table time event records where the user was stationary and then assign a station number
to those points based on proximity of that time event position to a preplot.  A copy of these
station-assigned time event records are placed in a table that is created and called, 'RECONSTRUCTED'.
This utility could be used in a situation where a vehicle driver forgot to log one or more points at
pad-down locations.
5) The field selection dialog has numerous controls that must be disabled or enabled depending
on the routine it has been tasked to handle. This slows the loading of that form.  A change has been
made so that the form loads quickly but there will be a couple of seconds when you will see a 'loading
controls...' label appear on the dialog.  After the first load, any subsequent loading is instantaneous
within the session.
6) The utility that identifies problems with field data now works on the currently selected query instead
of an entire table.
7) There is a new option on the Miscellaneous Settings dialog that affects the Field Selection dialog.
For tables that are neither Postplot or Preplot, the default height field name is Local_Height. The new
option allows the default field to be WGS84_Height. Another change on the field selection dialog
involves the type of field you must select as station  for routines such as selected points. The requirement
is for a numeric field however if you don't choose a numeric field, you are given the option to
proceed with what you selected.
Requested by Alan Stanton of WesternGeco.
8) Added an option to bypass normal routine for row counts of aggregate function queries (COUNT,
 MAX, MIN, etc,). The new optional routine can be selected on the Miscellaneous Options dialog. It
 determines if a query has an aggregate function, then fills a data reader object and counts the number
of rows in it. 
Project Manager
1) In the Project Manager Preference Menu, when you elect to download updated converters
and drivers to connect with and transfer data between survey devices, you will now notice a
checkbox that allows you to save the MSI installer on your system.
