Juan's project for featured-oriented synchro is on OW2Forge

OW2Forge give news on Tellus project (Juan's project part ) on : http://forge.ow2.org/forum/forum.php?forum_id=1764 for the featured-oriented synchronization.

Haiti

The situation in Haiti is an example where synchronization of POIs is a good option:

• As soon as a surveyor reaches an internet-enabled spot, new POIs are added to the database and WMS clients (for example in a coordination office) can see the changes instantly.


• As new POIs from surveyors A, B, and C get into D's handheld, D knows which areas need more attention and needs not update large amounts of raster data, since each point feature needs only a few bytes to be transmitted.

This is what the surveyor does:



This is what the WMS client shows:

Source code links

Mode A

• gvSIG Mobile and the Openmis application (both on the PDA) communicate via SOAP messages (web services)
• The source code for this (Tellus framework - Beta V1 version) can be downloaded from [here]
• See a video [here]
  

Mode B

• The Openmis libraries (JAR files) are added as a dependency in gvSIG Mobile, and a new FODB driver is used inside gvSIG Mobile
• The instructions to set up the Eclipse workspace for this are [here]
• See a video [here]
  

Tellus presentation done!

The Tellus presentation in the 5th international gvSIG conference took place as scheduled on Thursday 3 December 2009 at 4 pm at the Convention Center (also known as Obus) in Feria Valencia (Spain).

Tellus presentation coming up!

The Tellus project will be briefly presented at the 5th international gvSIG conference in Valencia (Spain) on Thursday 3 December 2009 at about 4 pm. I'll try not to damage anybody's reputation :-)

An alternative: implementing a FODB vector driver in gvSIG Mobile

One of the biggest advantages of the architecture proposed and implemented by Manu is that gvSIG Mobile provides an API that can be accessed via HTTP by any application (in this case the Openmis client application).

Another possibility is to add the Openmis client as part of gvSIG Mobile (ideally as an extension) so the overall architecture is simpler. I have done this with my gvSIG Mobile for Openmoko version. You can see here how it's done. Click to see large image:
