GeoCom has made available for download many scripts. There are a few programmes we have written, or recommend, that may be purchased, these include:

polycut
This programme will read standard seg-y and a set of vertices and output the seg-y data contained inside or outside the polygon. Currently compiled for Solaris 2.5 and above, may be ported to other operating systems if required. Typically this programme is offered as a bureau service, but some clients, with sufficient hardware, may find it more cost effective to purchase.
