[Roland Schweitzer <Roland.Schweitzer@xxxxxxxx>]

Hi Folks,

We are pleased to announce the release of LAS 7.2 (ftp://ftp.pmel.noaa.gov/pub/las/las.v7.2.tar.gz).  This version includes new features for vector variables and new products and capabilities for multiple variables.  The release notes (http://ferret.pmel.noaa.gov/LAS/documentation/las-release-notes-7-2/) have several example plots showing off the new features.

Please upgrade to this release and send your feedback to the list.

LAS Release Notes (7.2)

The current release is LAS 7.2 (December 2010)

This version of LAS requires Ferret 6.65.

Important Housekeeping Detail

The server configuration directory will now be installed under $TOMCAT_HOME/content/las/ instead of the the directory where you unpack your LAS and run configure.  You'll need to locate this directory and apply your changes to the configuration there after the install.

Major New Features

Multiple Variable Selection

LAS now supports selection of more than one variable from the same data set on the main interface.  When more than one variable is selected you can make new visualizations appropriate for the number of variables you have chosen.

1. Time series line plots will include all of the variables selected with multiple axis scales and line colors. 
2. You can make property-property scatter plots of two different variables.
3. You can also color the symbols in a property-property plot by the value of a third variable.

Vector Variables

1. Vector variables and vector plots are now supported (in XY, XT and YT dimensions). 
2. Vectors can be plotted in the vizGal comparison tool and the difference between to vector variable can be plotted in XY using vizGal.
3. vizGal itself has new layout and some new features that allow comparisons along any axis.   For example, you can make time series plots with a different point in XY selected in each of the panels.
4. The addXML utility automatically detects and configures many vector variable when scanning a THREDDS catalog or other netCDF data source with containing multiple variables.
