While acquiring seismic data for fault depth behavior analysis, one has to plot a variety of contour maps like velocity or depth contour maps for geodetic surveys, frequency contour maps for the data acquired, etc. One of the easiest and efficient ways of making contour maps is by using Surfer software.
I want to know how the data can be implemented and interpreted and if someone is ready to collaborate, I am enthusiastic to do so.
You should use GMT, not Surfer
http://gmt.soest.hawaii.edu/ which for example includes modules for various map-projections.
GMT is one of the most common free software package used by geophysics and I think it can be more suitable for your work.
But if you only need to calculate contour or grid surface you can also use Surfer but this is not free. Other option is try to use any free GIS package (like QGis) using special extensions like surface interpolation. The main advantage of GIS in this case is you can merge your information with existing geographic information but I am not sure if you will have special extensions for geophysics.
I can use both Surfer and Grapher and using full versions.
Near Surface Models are routinely prepared while doing onland data acquisition for determining the Optimum Depth (OD) of shot holes. I can also create Contour Maps using Surfer, I need to know if I can use sample shots for analysis.
