2D/3DPICKER:

      1) Rubber band picking option in Tracker. Left mouse click and drag in Tracker mode will remove and place new picks using Tracker algorithm

2) Increased length of data for projects created directly from traveltime (.gtt) files

3) Pinned menus for testing First Break Picking parameters

4) Allows multiple overlays of traveltime files

5) Option to plot predefined shot and receiver attributes above the seismic display

6) Zoom option on the display for easier navigation

7) Increased the size of the multi-file list so entire filename can be read

8) Option to build a project in parallel using multiple nodes

9) File sequence numbers to help identify segments in 3D multi-file project

10) Allows wildcard substitution in the file import list for multi-file projects

11) Recent Projects dropdown boxes

2D/3DTTIME:

      1) Building an initial velocity model by picking refraction turning points from a subset of shots and then interpolating an initial velocity model is now available in both 2D and 3D. Options include selecting an area with radius or drawing arbitrary polygons to define a subset of shots.

2) Choosing different subsets of shots to pick refraction branches to create a delay-time solution is now available for both 2D and 3D projects.

2D/3DPREP:

      1) Module MINPHASE to convert vibroseis data to minimum phase prior to picking first breaks

2) Minimum phase option to Process BANDPASS

3) Zoom function for the seismic display

4) Increased size of the multi-file list so entire filename can be read

5) Icon to switch easily between Wiggle Trace and Interpolated Density display 　

2D/3DIMAGING:

      1) Joint Seismic Gravity Inversion for both 2D and 3D

2) Overlay traveltime picks on top of data in waveform inversion QC

3) Forward modeling option only for waveform tomography to help in estimating time shifts without having to run an inversion

4) Capability to create a surface topography layer and QC before using in 2D waveform tomography

5) In waveform overlaying, can now interactively shift the synthetic shot gather upward or downward to visualize best alignment to determine the time shift needed in waveform inversion

6) Option to scale the input traces to the same RMS amplitude of corresponding synthetic traces

7) Capability to interactively change number of iterations and smoothing control during inversion

8) Option to recompute scaling factor after specified number of iterations

9) Toggle display between absolute and relative (percentage) misfits 　

2D/3DVIEWM:

      1) Utility to add, subtract, scale, and/or merge different 3D velocity/density models

2) Smart Binary converter now handles density models

3) 2DVIEWM now has both acoustic and elastic Finite Difference Forward modeling

4) Conversion from SAF to .3top and vice versa available

5) Option to convert from text file to .3top and vice versa, allowing user to import/export their surface of choice to use as a datum for static corrections.

6) Improvements in location of icons (moved all uphole items together; moved Delete icon)

3DPROCESSING:
New Module!

      Provides an approach for preparing gathers for the next module to pick velocities and create stacks to QC multiple statics solutions.

2DSTACK:

      1) Icon to easily toggle between different velocity models or stacks

2) Several minor enhancements

3DSTACK:
New Module!

      Designed to pick velocities and produce NMO stacks for multiple statics solutions at the same time. With TomoPlus, users can generate multiple statics solutions with different imaging methods. This module offers an efficient approach to QC the differences and their impact on seismic data processing.
