Thanks for these elements. They were useful in my discovering of mapserver. It worked in my case with : onSubmit="configure()".

Hi, it looks the source code in this page is far from complete.
Take a look at method "private void Page_Load" and then in the line : " for(int i=0;i "

Does anyone have the complete source code ?

Thanks !

You can do the same with GeoDjango or MapFish, is just a personal choice.
As said, I do not know MapFish, but with GeoDjango you are free to use any JavaScript mapping library you like including OpenLayers, Leaflet and others.
If you are using OpenLayers there are a couple of JavaScript libraries integrating it with major JavaScript frameworks: GeoExt and MapQuery.
For Django there are also a couple of packages that simplify the life of developers interacting with OpenLayers: django-floppyforms and django-olwidget

Thanks for the response! If you know of any comparisons/overviews of frameworks like these, they would be very welcome!

One difference I see between Mapfish and Geodjango is that Mapfish integrates client-side Javascript GUI components in the form of GeoExt, including OpenLayers. Geodjango doesn't seem to have this, right? What do you use to build a dynamic/Ajax web interface (incl. maps, legends etc.) on top of Geodjango? I'm looking for a framework to create a web application for viewing relatively simple geographic data on a map and for viewing and editing associated data (all in a PostGIS database), as well as generating some reports. I have experience with GIS programming, but not much with frameworks (including MVC, ORM...) like these, so I'm looking for something simple and elegant, but not too simple . ;-) Would you recommend Geodjango for this, or are there other (open source) solutions you can think of? (At first view, Django looks quite extensive and complex - but I could be mistaken.) Thanks!

Hi Markus!
But it looks to me that is just a way to execute and run GRASS commands from within Python script, and not a first class Python API to the underlying GRASS classes: am I wrong?
In any case, nice option for GRASS developers :)

Arjen, I have a very few knowledge of the Mapfish framework, and I am definitely not able to do a comparison between the two ones.
As far as I know it has a different approach than GeoDjango.GeoDjango has many goddesses including an an high level Python API interface to GDAL (OGR) and GEOS and is based on the Django web framework, as the name suggests.Mapfish uses Shapely, is based on the Pylons web framework (still a Python one) and does not provide an interface to GDAL, AFAIK.Looks like there are Mapfish versions for Rails and Symfony as well.But yep, we need to include this project to this post list as well, so I am going to edit the post and apologies to the Mapfish team ;)

Phil, at the time I have choose Python, also Ruby (and Rails) where on my mind. I even blogged about it and worked with it for a couple of projects.
You are right, the fact that plenty of GIS libraries exist for Python and not for Ruby where a major fact for opting for the former. For me also Python syntax is better than Ruby, but it is personal taste ;)
Regarding Python 3, I would definitely leave it out from your workflows at this time and concentrate on the version (most likely 2.7) that supports all of these libraries.

Thanks Paolo!

I'm also really interested in your view on different frameworks/toolkits for web mapping such as GeoDjango and Mapfish. What specific advantages do they have? Which one is suitable for which tasks? I'm evaluating different frameworks for creating a commercial web mapping application - would be nice to hear your opinion!

Arjen.

Also GRASS GIS offers meanwhile a Python API: http://grass.osgeo.org/wiki/GR... Through this access to powerful analytical algorithms is available even to the casual Python programmer.

Ruby has irb, which does the same thing as Python's command line interpreter.

I love Ruby and Perl but for some reason I have always had trouble getting into the flow of things with Python. It's mostly my own shortcomings as a programmer, but I'm trying to overcome them seeing as how seemingly every GIS package has some Python component to it these days. Perhaps I could ask you a bit of advice, should I be ignoring Python 3 tutorials for now, or are any / all of the OSgeo tools you listed above going to start migrating towards 3 in the near future?

Thanks to sharing a nice post. It is very convenient, if you're in your Linux machine root login. In this guide, we will use Linux to run on the console and install the software and required libraries.

Re: Managing documentation's translations with Open Source tools

Hi Jean, at a very basic extent, yes, that are the steps that must be implemented for migrating QGIS documentation to rst and Sphinx

Re: Managing documentation's translations with Open Source tools

Paolo Corti — Mon, 09 Jan 2012 05:16:12 -0000

Hi Mat, good point :)
Managing multiple versions of doc is also a key aspect to consider. So far, I agree with what you came out at SO: the doc specific to a release must just live in code repository.
We can then pull it out when we need to publish the doc for each release.
Look at the Django approach: https://code.djangoproject.com...

Jean-Roc Morreale — Fri, 06 Jan 2012 05:31:15 -0000

So now there is just to :
- port latex to rst
- create a new style (it can be done using libreoffice I think)
- port all the existing translations

Hobu has just told me via Twitter that Sphinx now, from 1.1, is supporting Internationalization :)
http://sphinx.pocoo.org/intl.h...
So if you are rendering your .rst files via Sphinx you do not need po4a at all
