On September 7, 2003 I released a new version Graphical which does not use the HPPT_REFERER variable. This variable was not being returned properly (or at all) by a number of commercial Internet service providers. This is a bad thing on their part, but I can avoid this dependence and selected to do so. I did not select to use both ways to communicate the needed data, so most of the old pages will not work with the new programs. This means that many cached pages will fail to function properly. Reloading the html file with the map, should fix the problem. Any locally stored Graphical Locater map pages will also need to be updated, see the "Custom Level 2 Maps" section below for the technical details. Please let me know if you encounter any problems.

Also on September 7, 2003. I fixed the TerraServer link, which had mutated in form again. I might complain, had I not just done the same thing!

On January 23, 2003 I added the state compostion to the HUC page for all cataloging units. A complete list is also available on our Hydrologic Unit Project Home Page

On June 10, 2002 I completed repairs to the Middle Snake-Payette and Lower Owyhee HUCs. These 2 HUCs were not delimited quite right in the first version.

On June 07, 2002 I added a series of county maps to the state map series.

On November 19, 2001 I inserted a new version of the trs2ll program kindly provided by Martin Wefald. This update adds Arkansas and corrects the North Dakota meridian from 6th Principal to 5th Principal. At the same time I combined state and meridian more explicitly for both input and output. It turns out that this is sometimes needed to uniquely define a position.

On August 10, 2001 I introduced a custom zoom map option. This option is available on every Graphical Locater result page and it should allow for easy custom maps. There is also a more detailed instruction page.
