[OSGeo-Discuss] Re: Support of 4D (time based) data sets
Sadly not yet. But there is more sadness to it. The code lives in JGrass and the current uDig version has a library mismatch that doesn't make the use of netcdf from JGrass possible. We are planning to solve this for the 1.2.1 release of uDig, but there is no strict timeline for that right now. Anyways the netcdf part in JGrass is actively maintained and you can indeed browse the maps through time, as well as the non-map parts (http://jgrasstechtips.blogspot.com/2010/01/netcdf-in-jgrass-non-spatial-part.html). I already had some requests in the uDig and JGrass lists to solve the problem, I will as soon as possible. I installed JGrass from: http://dev.fsc.bz.it/download/get_file.php?id=425 But how do I get the netCDF viewer now?

That is the problem, that older version didn't have it and the new one doesn't work because of libs mismatch. I have a version that we used for a course that should have the netcdf stuff in it, perhaps I could upload it somewhere if you want to try it?

I have a version that we used for a course that should have the netcdf stuff in it, perhaps I could upload it somewhere if you want to try it? Sure, would be great. I think your implementation (blog post) is just great and I'd love to see it implemented in a development version. Climate modelling and spatial analysis together in one program. Good. The access to climate data in netCDF offered by QGIS+GRASS by interfacing GDAL is somewhat inferior. We do not just want to display rasters but explore the time component as well.

Ok, I put a linux and a windows version at this link: http://tinyurl.com/32d6svr You will find a proper udig version + the update site that installs JGrass with netcdf support (as local update site). CF netcdfs are supported. You best import the netcdf through the udig data import wizard. To see non-gridded data, rightclick on the dataset and under operations you have a way to open the data viewer. For more, bug reports, comments, whatever, please jump into the uDig list. Don't want to get too offtopic here. The access to climate data in netCDF offered by QGIS+GRASS by interfacing GDAL is somewhat inferior. We do not just want to display rasters but explore the time component as well. Yes, that was our first aim in the google sommer of code project.

Hello Andrea, thanks for answering. I think it doesn't if you have small local datasets, I have never been able to zoom in. But at least it works... Sadly not yet. But there is more sadness to it. The code lives in JGrass and the current uDig version has a library mismatch that doesn't make the use of netcdf from JGrass possible. We are planning to solve this for the 1.2.1 release of uDig, but there is no strict timeline for that right now. I understand. Anyways the netcdf part in JGrass is actively maintained and you can indeed browse the maps through time, as well as the non-map parts (http://jgrasstechtips.blogspot.com/2010/01/netcdf-in-jgrass-non-spatial-part.html). Does that mean that if I install the current version of JGrass I'd get the functionality you implemented? I already had some requests in the uDig and JGrass lists to solve the problem, I will as soon as possible. Great. The target for the 4D GIS use is to visulaise modeling result in combination with more feature data. The analysis and modelling is done with other tools Note: I currently haven't settled on any system. I slightly favour the QGIS system because of its possibility to code a plugin in python. Anyway, thaks for your initiative and effort. Regards, Timmie ___ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss
