New WALLS build available

Postby Jeff Bartlett » Jan 13, 2010 1:18 pm

Walls users: the old version of Walls only included a table to calculate magnetic declination up to 2009-12-31. By my calendar, we've passed this date, which means if you want to survey a cave and have the program correct your azimuths to true North properly, you'll need to download the new version.

Available here: ... _setup.exe

Version 2, B8 Release, Build 2010-01-11

    * This build incorporates the latest International Geomagnetic Reference Field (IGRF) model, which covers the period Jan 1, 1900 through Dec 31, 2014. Also, a problem was fixed that caused the geographical calculator to stop working properly when the previous model expired on Jan 1, 2010. You can compare the declinations computed by the calculator with output produced by the IGRF calculator at the National Geophysical Data Center (NGDC) web site.
    * As suggested by Bob Osburn, the Editor Options dialog now has settings to control the initial width and height of an opened editor window. The default width was increased from 60 to 80 characters.
    * Several minor bugs were fixed, one being the occasional display of an empty or corrupted datum name on the Geographical Reference page of the Properties dialog.
