The full data set can be downloaded from: http://www.soest.hawaii.edu/wessel/papers/1997/WL_seamounts_1997.d This package contains six programs that may be useful to people who work with Plate Tectonic Reconstructions. The four programs are backtracker - Move points back/forth in time grdrotater - Reconstruct data grids using finite rotations grdspotter - Create CVA grids using grids of bathy/faa hotspotter - Create CVA grids using seamount locations originator - Associate seamounts with hotspot point sources rotconverter - Manipulate finite and stage rotations All programs are linked with libspotter.a (spotter.lib on DOS) whose source code is also provided. The makefile (UNIX) and makespotter (WIN32) will compile the library and link the programs. Being a GMT supplemental package it must be installed in a directory beneath the GMT src directory. It uses GMT include files and must be linked with the GMT and netcdf libraries. Because of how GMT3.2 or later are installed the compilation uses the same settings as the main GMT compilation which presumably have successfully been made. The SPOTTER package, like GMT, is released under the GNU Public License (www.gnu.org/copyleft/gpl.html). Man pages (both as UNIX man pages and HTML documents) are provided which give full descrition of the program interfaces. Furthermore, example scripts (UNIX shell and DOS batch) are provided which demonstrate how to use the programs on the enclosed data set and Euler poles. INSTALLATION: After GMT has been installed and the spotter directory is located in GMT's src directory, simply cd into spotter and type make install. Under DOS, cd into SPOTTER and type makespotter. Make sure that the DLL libraries GMT and PSL are in the %PATH% variable as set by gmtenv.bat. REFERENCES: -> The hotspotting technique: Aslanian, D., L. Geli, and J.-L.
