[Freegis-list] Edition, Geoprocessing and Georeferencing arrive at gvSIG. New 1-0-alpha release now available

[Mario Carrera]

Edition, Geoprocessing and Georeferencing arrive at gvSIG. The gvSIG 
project publishes an "alpha" release of gvSIG 1.0. 

The new version of gvSIG represents a great step ahead about the new features
compared to its ancestor and the current stable release: gvSIG 0.6.

The most important new feature in this version is the alphanumeric and graphical
CAD-like edition, one of the most demanded by the users. It also includes tools
for geoprocessing, image georeferencing and a WFS (Web Feature Service) client,
all the services in the OGC's Spatial Data Infrastructures are finally.

We consider that gvSIG can now cover the needs of the most users of geospatial
information, although we are conscious of there are a long path to walk on and
many things to be improved.

We are proud and impatient to announce all these new features and we have
decided to publish a pre-release named gvSIG 1.0-Alpha in advance, so you can
evaluate all these features on your own.

It is important to emphasize that this a development version which contain bugs
may be potentially important, so it is not recommended to use it for normal
uses.

We will continue with the usual distribution policy based in a set of unstable
releases (RCs) that will culminate in the definitive one, gvSIG 1.0.

gvSIG 1.0-Alpha is available from the Downloads section in the web page
 (http://www.gvsig.gva.es/index.php?id=descargas&L=1&L=2 ). 

We encourage you all to test and send us any bug or suggestions you may have to
the distribution lists.

            - Add, edit and remove points, lines and polygons.
            - Scale, rotante and move entities
            - Copy and paste entities.
            - Create polygons containing hole(s).
            - Split a graphical entity.
            - Visualize grids during the edition.
            - Simple selection.
            - Complex selection, allowing to select elements inside, outside, or

            - Console for input commands during the edition.
            - Create an annotations layer from a vector layer.
            - Do and undo the operations done in edition time. In addition,
there is a command stack containing the operations done done during the
edition.

- Locator:
            - Now supports zooming and panning.
            - It allows adding the same layers than the view.

- Geoprocessing:
     The following operations about geoprocessing are now supported:
            - Area of influence.
            - Dissolve
            - Clip
            - Intersection
            - Join
            - Union
            - Difference
            - Spatial link
            - Convex hull (in a point layer, is the line that envolves all the
points)

- Raster:
	- Images can now be georeferenced.
	- Modifiable brightness and contrast of a image.
	- New user interfaces for the tools:
	- Save to raster
	- Transparency by range of colour (by pixel).

- Tables: 
            - Table edition: add columns, add registers...
            - Tables can now be printed.
            - Writting DBF files and Postgres.

- Layout:
            - Now supports simple tables.
            - Now supports lines, polylines, and polygons.
            - Keyboard arrows move selected elements.
            - Do and undo support added.
            - Copy, cut, and paste from one layout to other support added.

- WMS Service: 
            - Added support Web Map Context (WMC) files. It is possible to
export and import views to and from Web Map Context (.cml) files.

- WFS Services: 
            - A brand new WFS client has been added. It is possible to connect
to servers following the OGC's WFS protocol (a new tab in the “Add
layer” dialog).

- Layer grouping: 
            - It is possible to change the visualization order of the grouped
layer.
            - Allows accessing to the table of attributes of the grouped layers
