[OSGeo-Discuss] Support of 4D (time based) data sets
Dear all, I am investigating in using netcdf as data format that could integrate the time dimension into GIS. The NASA tool Panoply (http://www.giss.nasa.gov/tools/panoply/) does this quite nicely. I have seen that there was an initiative from uDig in GSoC 2009: Getting time into the GIS for visualization and modeling puposes: netcdf support in uDig by Andrea Antonello http://jgrass.wiki.software.bz.it/jgrass/weekly_reports So my question: * has above mentioned development for netcdf support landed in uDig main code? * are there any other end-user GIS like QGIS or gvSIG that support time-based data sets like Panoply (going forward and backword in time-dependant modelled spatial data sets easily)? Thanks in advance, Timmie ___ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss

Hi Timmie, I am investigating in using netcdf as data format that could integrate the time dimension into GIS. The NASA tool Panoply (http://www.giss.nasa.gov/tools/panoply/) does this quite nicely. I think it doesn't if you have small local datasets, I have never been able to zoom in. I have seen that there was an initiative from uDig in GSoC 2009: Getting time into the GIS for visualization and modeling puposes: netcdf support in uDig by Andrea Antonello http://jgrass.wiki.software.bz.it/jgrass/weekly_reports So my question: * has above mentioned development for netcdf support landed in uDig main code? 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. Ciao, Andrea * are there any other end-user GIS like QGIS or gvSIG that support time-based data sets like Panoply (going forward and backword in time-dependant modelled spatial data sets easily)?

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

[OSGeo-Discuss] question about Tile retriever, if such a beast exists. . . .
All, I have a question about a tile maker routine that may or may not exist (or project about). I would like to be able to build a local cache of image tiles based solely on URL scripting, as in grab the tiles for an area automatically based on a Area of interest (BBOX) coordinate set. Anyone worked on some client code (either server or client side) for something like this? Sort of a pack and go Raster pyramid builder.

Re: [OSGeo-Discuss] question about Tile retriever, if such a beast exists. . . .
Bobb, hiya. Now, ... grab the tiles ... from where? I have a PHP script that given corner coords and zoom range, will build a directory set of tiles DL'd from OSM. (And the Open layers script that will call it.) Dunno if this is close?

grab from where, . . . . . from any (raster) image server. Your script sounds close, although I'm interested in grabbing directly from MapServer as well as WMS feeds. It would get me started and probably lead to a mechanism of some sort that would allow for retrieving from these various services at the very least.

[OSGeo-Discuss] Street address to coordinates database lookup?
In NZ as i guess in most places we have a national system of rural property addressing (RAPID) where the street number is based on how many meters down the road the property gate is. These are stored in Land Informations property on line database. My question is there any official or unofficial ways to access this street number to latlong coords data online? Googlemaps evidently has access to it for its searchs, failing better methods perhaps scrape their results page???

[OSGeo-Discuss] GRASS GIS 6.4.0 released
GRASS GIS 6.4.0 released http://grass.osgeo.org We are pleased to announce the new stable version of GRASS GIS. As a stable release GRASS 6.4 will enjoy long term support. While active development has continued in the background, due to our highly conservative stabilization policy this is the first official release of GRASS to introduce new features since October 2006. It supersedes the previous stable GRASS 6.2 line while remaining backward-compatible with all previous releases since 6.0. As such there are a host of new features to explore and it incorporates many structural improvements. GRASS 6.4 debuts our new and improved wxPython graphical user interface (wxGUI); Python is now a fully supported scripting language; and for the first time since its inception with a port from the VAX 11/780 in 1983, GRASS now runs natively on a non-UNIX based platform: MS-Windows. GRASS has been translated into twenty languages and supports a wide array of popular data formats. GRASS differs from many other GIS software packages used in the academic and professional worlds in that it is developed and distributed by users for users, mostly on a volunteer basis, in the open, and is given away for free. The source code is also freely available, allowing for immediate customization, examination of the underlying algorithms, addition of new features, and faster patching of bugs.

No need to screen-scrape; the GMaps API provides for geocoding in both directions. Secondly, White Pages also provides an API for US telco land-line numbers.
