We have some Tcl/TK apps that we use in conjunction with GEMPAK and one thing that came out of that was the need to be able to produce a text output from GEMPAK contouring routines. In other words, the countour level along with lat/lon points describing the contour are written to a file. The Tcl script then contours the data. We recently hired a new meteorologist programmer, Janelle Janish, who is dedicated to just programming and she wrote this new device driver. If this is something that might be of use elsewhere we will send her modifications up for your review for a possible enhancement to GEMPAK.
