Multiple datasets — g-Viewer
Multiple datasets

Multiple seg-y files viewer

Bring a whole survey into one project. g-Viewer's Seismic files panel takes as many SEG-Y files as you need, previews each one before it is fully read, and can watch a folder so new data loads itself — then puts them side by side in a workspace of linked views.

Seismic files panel with four datasets
One panel holds the whole project. Files go into the Seismic files panel by button or by drag-and-drop, and each brings its trace data, its text and binary headers, its trace-header table and its share of the location map with it. Nothing has to be read in full to be useful: a newly added file sits in Preview Mode, where its headers, a quick data image and a map of the traces read so far are already on screen — so a file that turns out to be the wrong vintage costs a look, not a full load. When you do commit, the reading happens in the background and the Progress View panel says where it has got to.
Loading

Add the files. Look before you load.

Two ways in, one panel, and a preview stage between adding a file and reading all of it.

Add as many as you need
The plus button opens a file browser for the SEG-Y files you want; there is no limit stated on how many the panel holds.
Or drag them in
Drop a SEG-Y straight onto the Seismic files panel. Larger files simply take longer to finish loading their contents.
Preview Mode
A newly added file shows its text and trace headers, a quick seismic image and a location map of the traces read so far — a quality check before the full import.
What arrives with a file
Trace data, the text header, the binary header, the full trace-header information and the file's contribution to the location map.
Read the headers in full
A file starts with its headers partly read. Load trace headers finishes the job — for the files you selected, or for every file in the panel at once.
Tidy the panel
The panel shows file name, full path and trace-header format; right-click to hide the fields you do not want and leave just the names.
Watch it happen
The Progress View panel tracks loading, so a long read is visible rather than a frozen window.
Save the project
Saving the project keeps the set of imported files, so the next session opens them again instead of repeating the upload.
Folder sync

Point it at a directory and stop importing.

Folder synchronization links a folder on your PC to the Seismic files panel. Anything new that lands there is detected and loaded on its own — the case the feature was written for is data being produced, updated or shared while you are still looking at yesterday's.

Sync
Link a folder

Sync folder at the top of the Seismic files panel opens a directory chooser. From then on, new seismic files added to that directory on the PC are automatically detected and loaded into the panel with no manual import step.

Unsync
Stop watching, keep the data

Unsync folder unlinks the directory. Automatic updates stop; everything already loaded stays in the panel exactly as it was, so ending the sync never costs you the session.

Geometry
Straight from the headers

Reading the trace headers in full updates the location map. If the positions look wrong there, the trace-header format is the thing to correct, then read again.

Surfaces
ASCII alongside the SEG-Y

The Surfaces panel accepts tab-delimited XYZ, space-delimited and CSV files, with X/Y/Z scalars and interpolation set on the way in.

Comparing

Several datasets, one arrangement of views.

A workspace is a graphical setup of views organised the way you work. The View Manager builds them, and there is no ceiling on how many of either you keep.

Workspaces & views
The arrangement side
Workspaces
An unlimited number of them, each holding an unlimited number of views — the central area where the project's data is displayed and analysed.
View Manager
Add or remove a workspace or a view from the panel or its right-click menu, rename with F2, and reach the per-view settings from the same place.
Kinds of view
Seismic sections, common gathers, header histograms, the location map, the QC graph, trace headers and 3D — all managed from the same panel.
Same line, new version
Zoom is preserved when you switch between different versions of the same line, so the comparison stays on the same piece of data.
Telling datasets apart
The identification side
File Info
Number of samples per trace, number of traces, sample rate and total record time for the selected dataset.
Appearance
Colour bar, inverted palette, normalization, min/max range, transparency, gain and AGC are per vista item, so each dataset can be displayed on its own terms.
From the map
The location map's Select line picks one line out of several 2D lines, or one volume out of several 3D volumes sitting at different coordinates.
Gather tabs
Seismic data, Common shot, Common receiver and Common bin each get their own tab, with Group by to sort on the headers you choose.
On the roadmap

Coming to multi-dataset work.

Two additions Geomage has announced for working across several datasets at once. They are not in the product yet — listed here because they are the shape of where this is going.

—
Concatenation of several files
Joining several loaded SEG-Y files into one, rather than treating them as separate datasets throughout.
—
Cross-plot QC across datasets
Trace-header QC on the cross-plot view driven from more than one dataset at a time. Today the QC graph cross-plots any three headers of the data you have selected.
More g-Viewer capabilities

Loading is where the rest of it starts.

Once the files are in, every other view works off the same set. These are the other g-Viewer topics.

FAQ

Questions, answered.

How many SEG-Y files can I have open at once?
The Seismic files panel takes as many files as you need, added with the plus button or dragged straight in. Each one loads its trace data, text header, binary header, trace-header information and its contribution to the location map, with the progress shown in the Progress View panel. The workspace side is equally open-ended: an unlimited number of workspaces, each holding an unlimited number of views.
Can I check a file before loading all of it?
Yes. Adding files puts them into Preview Mode, where you can read the text and trace headers, see a quick image of the seismic and look at a location map of the traces read so far. It is meant as a quality check — verify the content, the headers and the section before committing to a full import. When you are ready, Load trace headers reads them in full, for the selected files or for all of them.
Do new files appear on their own?
If you sync a folder, yes. Sync folder links a directory on your PC to the Seismic files panel, and any new seismic file dropped into that directory is detected and loaded without a manual import — useful where data is being generated, updated or shared continuously. Unsync folder stops the updates and keeps everything already loaded. Saving the project means the same files come back next session without re-uploading them.
How do I tell two versions of the same line apart?
The File Info panel reports the number of samples, the number of traces, the sample rate and the total time for the selected dataset, which is usually enough to identify a version at a glance. On the display side each dataset is a vista item with its own palette and scaling, views can be arranged side by side in a workspace, and zoom is preserved when you switch between versions of the same line.
