Data Categories

Question:

How can I group my data sets into categories meaningful to my users?

Example:

 

[Output Graphic]

 

Solution:

Starting with LAS v6.0, you can now organize your data in a hierarchical fashion for presentation. The genLas.pl command accepts the argument '-c catalog_file' and uses the hierarchical description found there to present the data on a series of pages during the data selection process. For a complete description of the xml syntax in the catalog.xml file please see the documentation on categories in the Customizing LAS section of the manual.

Note that items within a category level are presented alphabetically.

If you are going to use the catalog.xml file when generating your LAS interface, you will probably wish to change the following line in las/server/Makefile to reflect this:

  DOIT=../xml/perl/genLas.pl -c catalog.xml las.xml
