• shptrans 1.1.4 file released: shptrans-1.1.4-src.zip

  It was possible for a corrupt shapefile (one with infinite coordinates) to send shptrans into an infinite loop. This is now mitigated somewhat, although the bad file is still not reported. There was a rounding error in the handling of imperial units. The error was on the order of one in 200 million, so for most practical purposes, it probabably wasn't significant. This is now corrected. A few new units of measurement are now supported, including US Survey Feet (us_ft). There is a new option, -precise ("Extra Precision" in the ArcView wizard). Reverse projections (i.e. where the 'from' is not lat/long), and reverse gridshifts (where the 'from' is not NAD83) use an iterative method in which the amount of error reduces with each iteration until it reaches a predefined tolerance. The default error tolerance is significantly lower than is needed for typical GIS uses. The -precise option sets an even lower tolerance, and may yield better results for higher precision datasets or where the data will be projected back and forth many times. Usually you will not notice the difference, except that -precise runs a little slower. ArcGIS 9 has been released, so now the ArcGIS 9 pedata directory is added to the list of places that shptrans looks for gridshift files. The Nova Scotia high precision gridshift file is now available, and is named NS778301.GSB instead of the anticipated name, NS7783V2.GSB. When searching for an ATS77 gridshift file, SHPTRANS now accepts either name.
