Re: Problems setting up insitu data access

[Roland Schweitzer <Roland.Schweitzer@xxxxxxxx>]

Andrew,

You need to make sure the file insitu_operations.xml is in your 
$LAS_HOME/server directory.  If not copy it over from 
contrib/insitu/server/.

Then add a reference to it in the <operations> element of your las.xml 
file.  E.g.

<!ENTITY InsituOperations SYSTEM "insitu_operations.xml">
...
 <operations url="http://server.com/las-bin/LASserver.pl";>
  &StdOperations;
  &InsituOperations;
  </operations>

By the way, the paths /lasdata/operations/insitu_data_cdf and the like 
refer to element hierarchies in the XML document, not Unix file 
systems.  The software is looking for a definition in an element 
hierarchy like this:
<lasdata>
<operations ...>
<insitu_data_cdf.../>
...
</operations>
</lasdata>

which you will be supplying by installing the reference to the 
insitu_operations.xml file.

I'm using LAS version 6.4.1 on a itanium 64 running Redhat 9. I went through the 'make insitu' process and everything seemed to install fine. However, when I try to get any sort of output from the the insitu dataset I get an error.

Additionally, I can't find an "operations" directory within my LAS installation. I see a .jnl file named insitu_meta_xy in $LASHOME/server/jnls/insitu/ is this what LAS is looking for? I don't see any files named insitu_data or insitu_data_cdf anywhere in the $LASHOME directory.
