Scripting Dynamic Maps: Some Examples and Experiences with Tcl/Tk

  • Jason Dykes

Abstract

This chapter is based upon experience gained whilst using the Tcl/Tk scripting language and graphical toolkit to produce fast interactive maps. Tcl provides familiar programming features and high level control of external processes, whilst Tk adds graphical user interface (GUI) windows. In combination Tcl/Tk supplies a rich environment for developing new code and linking existing software with GUIs. The language originated at Berkeley in the late 1980’s and has developed rapidly, accumulating a large user community and being further developed by Sun Microsystems. Tcl/Tk remains an ‘open source’ package that is freely available for download from Scriptics, a platform company for Tcl/Tk formed to provide support and develop additional commercial tools (Scriptics 1998).
