[Talk-br] Estados Unidos libera arquivos de fronteira internacional com maior precisão Fwd: [OSM-talk] Fw: Updated, more detailed international bdy. shapefiles (US Dept. of State Office of the Geographer)

[Arlindo Pereira]

Se alguém quiser trabalhar na importação de fronteiras internacionais, um
órgão governamental dos EUA liberou um arquivo em domínio público com
precisão supostamente maior que o que temos atualmente no OSM.

 All,

    I have you all on my list of folks interested in detailed international
boundary lines.*

     An update to our worldwide Large Scale International Boundaries (LSIB
version 5) can be found as of today at
http://HIU.state.gov<http://hiu.state.gov/>(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.

     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.

    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.

    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.

all the best,
Dave

*if that’s not or no longer the case, let me know
