Hi all<br>my name is Giovanni Onofri and I am working to integrate in a single application GeoReport and Spatialytics in PentahoBI platform using CDF extenstion.<br>This week I did a global overview on various software and languages that will help me in the near future<br>

Dear List,<br>
<br>
I am Christian Martin Reinhold and I am working on a client-server<br>
communication for extending a Web Symbol Service (WSS) on gvSIG. This week,<br>
I have been busy on the server side, defining its technology, which is<br>
finally django and pinax, and start implementing on it for the first days.<br>
Then, I started thinking about how to make this communication possible via<br>
Web Service, and also reading the OGC specification for SLD files.<br>
<br>
All the related documentation is and will be available at the following<br>
site:<br>
<br>
<a href="https://confluence.prodevelop.es/display/WSS/Home" target="_blank">https://confluence.prodevelop.es/display/WSS/Home</a><br>
<br>
Now you can just read about my first week [1] and about the project in<br>
general [2], as well as the points stated at the weekly meetings for<br>
determining goals for the next weeks.<br>
<br>
The code of the project will be uploaded via SVN at one of the<br>
prodevelop-gvsig files next weeks.<br>
<br>

><br>

><br>
> - code to export grass elevation data to ossimplanet (g.ossim) the<br>

> Hi List,<br>
><br>
> This week, I implemented a module that computes the shortest path<br>
> between all pairs of nodes in the graph. You can also specify which<br>
> pairs you are interested in, so that the module does not have to<br>
> produce the entire NxN matrix. Also, I started on network flow<br>
> modules. So far, I have implemented a flow algorithm and a simple<br>
> module that finds the maximum flow between two given vertices(Well,<br>
> for debugging purposes, it can handle only the flow between nodes 215<br>
> and 219, so far....) Anyway, here is couple of pictures:<br>
> <a href="http://people.ksp.sk/%7Edano/grass/mfu.png" target="_blank">http://people.ksp.sk/~dano/grass/mfu.png</a>,<br>
> <a href="http://people.ksp.sk/%7Edano/grass/mfu2.png" target="_blank">http://people.ksp.sk/~dano/grass/mfu2.png</a>. One cross is source, the<br>
> other one is sink. Blue edges correspond to low flow, green to medium<br>
> and red to high flow. I used speed limit as edge capacities. Although<br>
> it is not the case in the two pictures I posted, the forward and<br>
> backward capacities of an edge can be different.<br>
><br>
> For the next weeks, I plan to revise for my exams. As you may be<br>
> aware, I have started two weeks earlier and so I will take a short<br>
> break now.... Currently, I have no blocking issues.<br>
><br>
> See you in July!<br>
