Hi Sarang,
Regarding support for GIS users, some comments to add:
- We recently added shapefile output to LAS -- especially
important for curvilinear coordinate systems, which many GIS
applications cannot handle as grids. This is a BETA capability
... needs further testing and probably refinements
- The simple "ArcGrid" output is a standard capability in LAS --
suitable only for data on regularly-spaced lat-long grids (but
the tools are configurable to transparently regrid more complex
grids to this simpler form)
- Roland described how we are undecided what the optimal path
forward is with respect to WMS. Since LAS relies on TDS (or
actually "F-TDS") for server-side transformations of data
(computing averages, variances, extrema, etc.), it is a
guarantee that there is always a TDS available as part of an LAS
installation. An appealing path forward might be to configure
LAS so that it provides WMS via a simple interface layer over
the WMS that is embedded into TDS. This might also enable us
to improve on the default WMS getCapabilities document that TDS
generates, because LAS "knows" more in general about the
datasets it serves than TDS does.
If you are interested in teaming up with us on any of these topics,
we'd welcome the discussion.

Hello All,
After long time i am joining this forum once again .
Last time as Roland and his team mate suggested me what type
of Java Development can Possible to enhance the LAS.
Here are the Few Suggestions.
1. GIS Integration with LAs (Will take time and brain Storming
discussion)
We've had some conversations about this in our group. FYI, there
is an implementation of a WMS buried in the LAS code, but a lot of
work in that area has gone forward in the ncWMS code that is now
wrapped in the TDS. Working with the ncWMS/TDS folks might be a
good place to make progress with GIS/OCS related improvements, but
we are certainly interested in ideas in this area related to LAS.

2. Localization and Internationalization
of LAS
This would be great. We have almost no provisions for
internationalization so you'd be starting at the beginning.
3. OpenLayer modification
There is an undocumented hook in the code to set the map server
for the base map. We'll have it documented with an example in the
next release.
Apart from this many small enhancement we
can make .
Like i am currently working how LAS can help to use CDO(Climate
Data Operator ) in ferret background mode.
Has anyone worked on inserting CDO in LAS.
This is a very interesting addition. We have built a backend
service for NCO in the past and we would be very interested in a
service for CDO and NCO. These operators duplicate many of the
capabilities handled by Ferret, but there may be some interesting
things that could be done with these services.
Please keep us informed on your progress.
Roland
Thanks and Regards
Sarang Gandhi
