<div class="yiv3968925520WordSection1">
<div class="yiv3968925520MsoNormal">All,</div>
<div class="yiv3968925520MsoNormal"> </div>
<div class="yiv3968925520MsoNormal"> I have you all on my list of folks interested in detailed international boundary lines.* </div>
<div class="yiv3968925520MsoNormal"> </div>
<div class="yiv3968925520MsoNormal"> An update to our worldwide Large Scale International Boundaries (LSIB version 5) can be found as of today at
<a rel="nofollow" target="_blank" href="http://hiu.state.gov/">http://HIU.state.gov</a> (under “data”, down near the bottom (“June 2013 LSIB v. 5”, 17mb.)) This data set is in the public domain; no restrictions on its use. It includes update such as an approximation of last month’s ICJ
ruling on Burkina Faso-Niger’s boundary.</div>
<div class="yiv3968925520MsoNormal"> </div>
<div class="yiv3968925520MsoNormal"> Also, after many requests, Kate Schaefer (in our sister “HIU” branch) and I put together last fall a worldwide country polygon file as well, which most closely matches the Sept. 2012 version (LSIB4b) of our international lines. It
is posted in the same place. </div>
<div class="yiv3968925520MsoNormal"> </div>
<div class="yiv3968925520MsoNormal"> We’re fortunate in this office (intact here at DoS since 1921) to have or have easy access to voluminous maps, treaties, and other international boundary information from the past 150 years. We are also fortunate that our colleagues
in DoD (NGA) and in the UK (DGC) have been researching and digitizing international boundaries since the late 1990’s; we continue to work closely today. That’s given us a pretty good head start on quality control for the world’s 320-some international land
boundaries.</div>
<div class="yiv3968925520MsoNormal"> </div>
<div class="yiv3968925520MsoNormal"> Considering the caveats in the attached doc (i.e., we follow US govt. policies; certainly anyone else using this data set can change it to conform to their own policies), we always welcome from professional geographers like yourselves
any corrections, suggestions, questions on international land (not maritime!) boundaries, their history, alignments, lengths, etc.
</div>
<div class="yiv3968925520MsoNormal"> </div>
<div class="yiv3968925520MsoNormal">all the best,</div>
