Support of EPSG 5806 in gvSIG CE

We are pleased to announce the support of EPSG 5806 in gvSIG CE. This is a cartesian coordinate system used in engineering environments (for example, surveys) as an XY, non-world and unprojected coordinate reference system. We began this task by evaluating the problem [1] and finally we produced a document with a full analysis as well as the possible solutions [2].
After some work, we managed to implement a good solution in the short term, minimizing the efforts. We leave the integration of GeoTools as a possible solution in the middle-long term [3].
This feature will be available in the next gvSIG CE release.
Thank you very much to David Bibby from Landesdenkmalpflege Baden Württemberg for supporting this feature and to Benjamin Ducke for its contribution and further development.
A continuously updated release announcement, detailing the progress on new features and bug fixes can be found here
Best regards
Victor González

SQLite support

Another nice feature for gvSIG CE: we have implemented SQLite support as a new
gvSIG CE extension.

With this new development it is possible to add a new layer to a view from
a SQLite file with spatial data. Besides, it is possible to load SQLite files without
spatial data (or with spatial data but ignoring it) as new tables in gvSIG CE.

In order to add the layer/table, a new wizard has been created. This wizard is very
similar to the wizard for simple files but adds some extra inputs on the bottom to
specify which of the tables contained in the SQLite file must be loaded and which
geometry column to use if it is going to be loaded as a layer:

Moreover, the SQLite support is not reduced to data visualization. It is also possible
to edit SQLite data by using the common editing tools for layers and tables. For this
purpose, the new extension uses GDAL/OGR to access SQLite data, which is a guarantee of stability and performance.

In the technical aspect, we have used the official GDAL/OGR Java bindings to access
GDAL/OGR from Java. As a side task, we have also replaced our custom JGDAL bindings, used for raster data, with the same official GDAL Java bindings. Thus, we don't have to maintain the JGDAL bindings but simply build the GDAL ones.

The GDAL version we have used for this development is 1.10. This feature will be
available in the next gvSIG CE release.

Patches for better window management

Dear all,
the borders of internal windows were just one pixel thick, so it was very hard to e.g. resize a view or attribute table window.
With this update you should see the difference immediately. The broader window borders apply to all resizable internal windows in gvSIG CE (views, maps, attribute tables, etc.).
The updated Plastic XP theme has much wider borders and uses a thin black outline, which makes it easier to tell apart the contents of overlapping data windows.

Have fun!

Java version of SEXTANTE

Dear all,

we are pleased to announce that you can download the newest Java version of SEXTANTE in gvSIG CE.
We have also updated the SEXTANTE user manual.
Would you like to improve the Java version of SEXTANTE? Your help is well appreciated!

If you are interested in improving any aspects of the SEXTANTE development, we encourage you to provide additional human resources to the project and work e.g. on some of these issues: bug fixing, creating new functionalities, writing documentation, customizing SEXTANTE, etc.
Contributing and participating actively in the development of SEXTANTE is definately important to keep growing this wonderful geospatial library.

If you are interested in collaborating on one of these or any other aspects, please sign up to our community mailing list. Once there, please introduce yourself and tell us what you are interested in.
Best regards,
Ruth from gvSIG CE Team

gvSIG CE at FOSSGIS 2013

Dear all,

FossGIS 2013 is taking place from 12th - 14th of June `13  in Rapperswil, Switzerland.
All information regarding registration, location and program of the event can be found at [1].

I would like to announce some topics regarding gvSIG CE and invite all of you to join:

- "Geoprozessierung mit Open-Source DesktopGIS": Benjamin Ducke will present gvSIG CE with SEXTANTE and GRASS GIS, which together provide a powerful tool for all matters relating to the theme "geoprocessing":

- "Kartenerstellung und Bearbeiten von Legenden mit gvSIG CE": In this 1.5 hours workshop, Ruth Schönbuchner will give an overview on gvSIG CE capabilites regarding labelling, legend generation and map layout production:

- Share interests and discussion at gvSIG CE BoF (Birds-of-a-Feather)-meeting on thursday, 13th of June `13 room no. 1.271 (table 1):

We are looking forward to meet you at FossGIS in about 2 weeks!
Best regards,
Ruth Schönbuchner

Evaluation of how to implement a cartesian coordinate system support (EPSG:5806)

Hi all,
some of the gvSIG CE users need this CRS, so we are evaluating how to implement it.
Please, if you can, read the wiki, add anything you consider important and share your thoughts.
