Introduction: DSWIN is free ["NGS"] software designed to read NGS .dat files of ["datasheet"]s and print user selected fields from the datasheets. It is a data mining tool. Generally .dat files containing all the datasheets of a county are downloaded from the NGS Yearly Archives [http://www.ngs.noaa.gov/cgi-bin/ds_archive.prl page]. The output of DSWIN can be imported into a spreadsheet program for sorting by the various fields and printing.
