The WGS 1984 datum is essentially identical to NAD 1983. This program works only for the main Hawaiian islands and nearby ocean areas. All output files will be written to this directory, and will be given the same file names as the input shapefiles. Therefore the output directory must not contain any file having the same name as an input file. Large files may take over an hour and therefore multiple file conversion may best be done overnight.
More powerful configurations produce substantially faster results.
The transformation from Old Hawaiian to NAD 1983 is substantially faster than the reverse transformation. This provides a means for logging the progress of the program. There is no need to keep this view in your project after the conversion is finished. This message view may not refresh immediately when larger files are being converted. If, after opening the Dialog, you need to return to the project for any reason, you should close the dialog, then restart it.
