[Paraview] Geoprocessing using ParaView

[Moreland, Kenneth]

Junlin,

I am adding the ParaView mailing list to the recipients of this reply so that others may fill in the gaps in my knowledge.

Based on your description of SciNet, it should be straightforward to compile ParaView and set up the server.  There is information on how to do both on the ParaView Wiki (http://www.paraview.org/Wiki/ParaView).

I don't know much about GIS in general and almost nothing about ArcGIS specifically, but the basic types of data are supported within ParaView.  I know that ParaView supports the loading of DEM files, which appears to be a common format for geographic data.  The surface terrain from elevation data is also a common question with a simple answer; it can be achieved by applying the "Clean to Grid" and then "Warp by Scalars" filters.

I hope that helps.

-Ken

Dear Dr. Moreland,

We are exploring the possibility of spatial analysis using SciNet supercomputer. This cluster is currently the most powerful computer in Canada and the 15th in the world.

SciNet is currently running AIX 5.3 on the TCS and CentOS 5.3 on the GPC. Moab+loadleveler on the TCS and moab+torque on the GPC.  IBM XL compilers on the TCS. Intel and gcc compilers on the GPC along with a couple of MPI releases (recommending intel mpi or openmpi).

We have some problems here with processing very large datasets because of the RAM and speed limit of desktop machine. SciNet supercomputer may provide a solution to this challenge. I notice ParaView has the capacity of parallel processing. Just wonder if it is capable to handle geographic information, such as surface interpolation from elevation point data. I guess you already use or know of ESRI ArcGIS. Is ArcGIS and ParaView data format convertible? We only need some basic function of GIS using ParaView for now. But we need to handle very large datasets.

Thanks for your time.
