You have to enter all connection and new layer's column parameters by hand each time. No better than doing this from CLI or pgAdmin. Thanks for the gvSIG hint. Unfortunatelly it provides only five data types, forces 'text' datatype for string data, which is an overkill and way slower than varchar when not needed, forces 'double precision' for floating point. I was able to crash it twice (the 1.1.1 version) within few minutes of usage. If it was just me I could maybe stand this but not my client. More hints welcome. Maciek From bernhard at intevation.de Sun Feb 3 02:15:30 2008 From: bernhard at intevation.de (Bernhard Reiter) Date: Sun, 3 Feb 2008 02:15:30 +0100 Subject: [Freegis-list] Thuban 1.2.1 released. Message-ID: <200802030215.34911.bernhard@intevation.de> Bringing out to light what was hidden - is a fitting motto of this maintenance release. Thuban had a few interesting Extensions, but if users saw them depended on their customisation. Now all Extensions can be enabled per installation. Not all of these gems have been fully brought back to life. With ogr you can still open up all formats this powerful library can read. Wms currently needs a makeover which is on the list for the next release. Of course a number of defects have been fixed. The Thuban 1.2.x series seems a little less stable than usual because of the way we are half way there to fully support unicode internally. But thanks to our users, all reports help us to iron out the problems! Thanks to all that have send us feedback! Download the source from http://wald.intevation.org/frs/?group_id=6 or push your packagers. ;) Bernhard Reiter Didrik Pinte Thuban is an Interactive Geographic Data Viewer - extensible and multi-platform - mainly writting in Python. Changes up to Thuban 1.2.1 (released 2008-02-03) =========================== - Rendering: Thuban's accelerated shapefile renderer is now robust against shapefiles which contain empty shapes. - Text Encoding: Progress to make Thuban run better with different encodings and locales. (Bernhard Reiter) + The class generator selector will work even in other languages. (Reported by Samuel Mesa) + Layer titles from filenames are saved in the correct encoding, so strings can be assembled from them, e.g. for the Layer Projection dialog. (Reported by Samuel Mesa) + Fixed [#586] (projection exception when changing projection) (Reported by Stefanie Gunkel) - PostGIS support: Migrated from psycopg1 to psycopg2 (Didrik Pinte) Now UTF8 environments are better supported. - Windows packaging improved. Also it got easier to make a windows package that inclused everything. (Didrik Pinte) - move to wxPython 2.6 completed (Didrik Pinte) - Using the alpha channel for displaying raster images all the time. There is no selection possibility anymore for "masktype". (Bernhard Reiter) INCOMPATIBLE with Thuban 1.1 (development series) and 1.2.0: Ignoring the saved masktype in .thuban files, using "alpha" in all cases. With wx2.6 there is no need for other mask types anymore. Doing this change fixes a problem on the windows platform, where masktype=bit did not work so far. - Translation updates + Extensions are now localised as well (Bernhard Reiter) + German (Bernhard Reiter) + French (Didrik Pinte, Daniel Calvelo) + Spanish (Daniel Calvelo) + (New) Czech (Jachym Cepicky) - Problem fixes: + Fixed [#403] "can not add raster layer". Adds the ability to open more then one raster file from one open dialog by multiple selection. Thanks to Jachym Cepicky and Bernhard Herzog. (Bernhard Reiter) + Printing reenabled under some platforms. (Bernhard Reiter) - Extensions (all Bernhard Reiter) + ogr: Some fixes to make it work with encodings and database connections. + wms: Some attemps to revive, but found out that PyOGClib is abandoned and does not work anymore. Needs work. + Extentions are now all under the menu entry with the same name, their maturity will be indicated by leading string in the menu text. + New installation wide configuration file thuban_cfg.py which by default tries to import all interesting Extensions coming with Thuban. Notable issues: - gdal version 1.5.0: The following issue was reported with this new version: https://wald.intevation.org/tracker/index.php?func=detail&aid=587 gdal 1.5.0-3 (from Debian sid) leads to error messages and test failures - Extension OGR: - Two tests fail (probably because of an ogr/shapelib problem.) https://wald.intevation.org/tracker/index.php?func=detail&aid=91 The failure looks harmless. As the ogr layer support is beta it did not block the release. - Is slower than native Shapefile support. - Classification might not work. - Extension WMS: probably does not work correctly, thus it is disabled in Thuban/thuban_cfg.py. - Extension profiling: makes use of a non-free "profile" module which therefor will not be available on all python installations. Consequently it is also not enabled by default. - Because we enabled translations for the Extensions only recently, some translations will be outdated more then usual. -- Managing Director - Owner: www.intevation.net (Free Software Company) Germany Coordinator: fsfeurope.org.

This worked fine, > except the image quality from ArcGIS was horrible, particularly when > zoomed in (no anti-alias). I don't think your approach will work. Even if you manage to create a very large geotiff, re-sampling it to create low resolution tiles would produced anything but nice looking maps. Also, for high zoom levels the image size will blow your memory away. Creating good cartography would most certainly require per zoom level styling. > > I'm a now trying to use mapnik (mapnik.org) to create the same > image at > higher quality.

Have a look at : http://trac.openstreetmap.org/browser/applications/ rendering/mapnik/generate_tiles.py [1] This script generates tiles with all styles and data defined in : http://trac.openstreetmap.org/browser/applications/rendering/mapnik/ osm.xml > > Is there something else that I can use to create the tiles needed for > the OpenLayers app?

I'm not familiar with gdal2tiles.py but as I mentioned above, re- sampling vector maps won't produce high-res, high-quality tiles (assuming this is what you're trying to achieve). You might try creating two layers : chop your raster data with gdal2tiles.py and create transparent overlay tiles using Mapnik. Also, Mapnik supports gdal raster directly and you can generate high quality tiles with raster and vector combined. see [1] HTH Artem > > > _______________________________________________ > Freegis-list mailing list > Freegis-list at intevation.de > https://intevation.de/mailman/listinfo/freegis-list > From carrera_marrod at gva.es Mon Feb 4 14:41:31 2008 From: carrera_marrod at gva.es (Mario Carrera) Date: Mon, 04 Feb 2008 14:41:31 +0100 Subject: [Freegis-list] gvSIG update version 1.1.1 and 3D pilot extension for gvSIG 1.1.1 are available In-Reply-To: <47A456D6.6040703@o2.pl> References: <4783794A.4080604@gva.es> <47A456D6.6040703@o2.pl> Message-ID: <47A7160B.8040400@gva.es> Hi Maciej, thank you for your comments.

For me a software package "with installation prerequisites" ("prerequisite" as a noun), is a package that needs other software to run. I understood "with installation prerequisites" = "with installation requirements" = "requires additional software". Maybe I got it wrong. Sorry for the fuss then.

Mapnik can generate tiles from vector and raster data sources (including gdal raster). gdal2tiles.py is for *raster only* tiles. > If [1] was a link it did not come > through in the email.

So far this extension only allows access to vector layers in the database. From the gvSIG project, we would like to sincerely thank the Ministry for Sustainable Development and Territorial Planning of the Region of Murcia for its dedication to supporting this new extension, substantially improving the application for the benefit of all members of the gvSIG community. It is available in the Extensions option from the Downloads section of the web page (http://www.gvsig.gva.es/index.php?id=1873&L=2). Advice: To install this extension you must have correctly installed gvSIG 1.1.1 version -- Mario Carrera Rodr?guez Grupo SIG-CAD / gvSIG Asistencia t?cnica externa Servicio de Organizaci?n e Inform?tica Conselleria d'Infraestructures i Transport Generalitat Valenciana Valencia (Espa?a) From henning.lorenz at geo.uu.se Wed Feb 13 08:59:59 2008 From: henning.lorenz at geo.uu.se (Henning Lorenz) Date: Wed, 13 Feb 2008 08:59:59 +0100 Subject: [Freegis-list] FOSS4Geo session at the Geosciences World Congress (33rd IGC 2008 in Oslo) Message-ID: <47B2A37F.3040702@geo.uu.se> FOSS4Geo related science and development is represented at the Geosciences World Congress in Oslo with an own session (see copy of earlier announcement below).
