New Version of MARPLOT Avaliable

CAMEO Community Members,
A dramatically updated version of MARPLOT is now available for
downloading, along with a maintenance upgrade to ALOHA.
MARPLOT 4.0, available as of today, is compatible with Windows XP and
Windows Vista.  Working in its easy-to-use GIS interface, you can switch
quickly between three basemaps: standard map files, high-resolution
aerial photos, and topographical maps.  You can draw overlay objects on
the basemaps, customize your map view by specifying which objects and
map layers are shown, and get LandView-like population estimates inside
selected areas.  You can click on a location of interest to get its
elevation and an instant weather forecast, and you can easily display
ALOHA threat zones on the map.  Included web mapping services enable the
latest U.S. Census county maps, and state and national map layers to
automatically download as you work in MARPLOT.  Download MARPLOT 4.0 from
the CAMEO website

If you're a Macintosh user, note that MARPLOT version 4.0 is currently
available only for Windows.  A Macintosh version is planned for the
future.  In the meantime, if you have an Intel-based Mac, you can run
MARPLOT 4.0 in Windows using Boot Camp or virtualization software that
allows you to run Windows on your Macintosh.  Otherwise, you can download
the previous version of MARPLOT for the Mac
<http://www.epa.gov/emergencies/content/cameo/marplot_mac.htm> (version
3.3.3).
Also available as of today is ALOHA 5.4.1.1, which includes an updated
chemical library, now with updated DIPPR data and updated toxic levels
of concern (AEGLs, ERPGs, and TEELs), and a fix to a bug that prevented
users from entering heat of vaporization when adding a new chemical to
the library.  ALOHA 5.4.1.1 is compatible with Microsoft Windows and with
Macintosh OS X.  We recommend that all ALOHA users download ALOHA 5.4.1.1
