gvSIG 2.1 is here!

The gvSIG Association announces the publishing of the gvSIG 2.1 final version. This version, that is the first one based on the new architecture orientated to users, has a lot of new features as you can see now. Besides the new functionalities and the correction of a great number of errors that have been detected thanks to the community collaboration, we want to highlight the availability of a distribution for Linux 64 bits and portable versions for Windows as well as for Linux.

Together with the gvSIG 2.1 releasing we publish the new gvSIG website, that includes the old gvSIG Association website as well as the project one, and at the same time a knowledge portal about the gvSIG technology. Besides this new website will be to make the new products of the gvSIG catalog visible, like gvSIG Roads or gvNIX.

We want to take advantage of this announcement to thank all the people that have collaborated in making this new version reality, and all the entities that have counted on the gvSIG Association services to solve their needs on geomatics, helping to guarantee the sustainability of the project at this way.

We hope you enjoy all the novelties of this version, that are here.

We hope 2015 is a year with a lot of novelties, where gvSIG 2.1 and the new website are the first of them. Be aware of them!

My idea of this post is to go a little bit further than just telling you about new features. I will add some visual information and links for knowing more about this new improved version. Let´s go….

Georeferencing. It is possible to put a reference system (geographical coordinates) to a digital image with pixel coordinates (rows and columns)  01
 02 Principal components. The analysis of principal components is a multispectral conversion, aiming to avoid the use of redundant information in the sidelines of the image. The technique allows to convert a sideline series in new variables called correlated components, that absorb almost all the variability of the data in a subgroup of the initial bands. The advantage is that most of the information is at the first three bands that have been created, that allow to keep almost all the information with less space.
Tasseled-cap. The transformation tasseled cap is a conversion more general than the one with principal components, having as well indexes with a concrete physical meaning. So, it´s possible to determine the brightness value, the greenish and the humidity of the soil. The transformation Tasseled is focused on pointing the relevant spectral characteristics the vegetable areas during its development, to be able to take out specific crops and other crops of other vegetable surfaces using the spectrals ranks of the Landsat multitemporal images.  03
 04 Masks by regions of interest. With this functionality, from a previously selected area is possible to make it visible and to have a fixed value assigned by the user on the external side of the interest area or vice versa.
Set projection. Set projection to a raster layer of the View.
 05 Change data type. It allows to change data of a raster image
Create multi-file layers. It allows to add more image bands from other files and create new multi-file layers.  06
 07 PostGIS raster support. It allows to load in gvSIG, raster layers saved in a PostGIS database. These raster layers will be added to the gvSIG Views and they would be used as local raster layers.
Expressions legend. It allows to create legends representing the data linked to a concrete expression defined by the user. This link is about new legend types in gvSIG 2.1: https://blog.gvsig.org/2014/12/02/gvsig-2-1-a-full-set-of-legends/  08
 09 Proportional symbols legends. It allows to create legends using the size of a symbol to represent the different values of the layer´s numerical attributes. The size of each symbol show the real value of the data
Graduate symbols legends. It allows to create legends using the symbols size for showing different value ranks. The quantitative values will be classified in ranks with minimum and maximum values. In each rank, all the entities will have the same symbol.  10
 11 Dot density legend. It allows to create legends by dot density for layers with numerical attributes.This type of legend show the quantity of an attribute in a selected area. Each dot represents a specific number of entities.
Quantities by category legend. It allows to create legends combining two types of legends in only one: graduate symbols and intervals.  12
 13 Bars legend. It allows to create bars legends for obtaining numeric attributes of the elements of one layer.
Pies legend. It allows to create pie legends for obtaining numeric attributes of the elements of one layer.  14
 15 New layout with TOC (table of contents) included.(Layout). In gvSIG 2.1 a new document Map has been created with the integration of the layers management (TOC) inside of the maps builder. It is a real improvement in mapping production tasks, because the user will not need to be changing from the document View to Map every time that a new action is required; such as add a new layer, modify the symbology or labelling. https://blog.gvsig.org/2014/11/14/gvsig-2-1-improving-cartographic-production/
New grid functionalities. In the new document Map in gvSIG 2.1, we will find the functionality of create an improved grid and be able to set up all the visual parameters (intervals, labels and symbols). https://blog.gvsig.org/2014/11/17/gvsig-2-1-configuration-of-the-grid-in-the-new-map/  16
 17 Export to KML. It allows to export to KML, with options for exporting balloons and labels.
Advanced labelling. It can be defined by the user, with many more options and more powerful than basic labelling. They are three methods: Only labelling when the entities were selected, defining different entities classes and label them in different way or labelling all the elements in the same way. https://blog.gvsig.org/2015/01/28/advanced-labelling-in-gvsig-2-1/  18
 19 Halo option for labels. It allows to create a halo for the labels, with colour and size defined by the user, improving the visualization of the texts.
Toolbox: Unified geoprocessing manager. All the vector and raster geoprocesses have been integrated in one only, called Toolbox. One of the advantages is to be able to use all the geoprocesses in the modeller.  20
 21 Alphanumeric editor in Views. It allows to edit the attributes of any element in one layer without the need to go to its table.
It works very similar to the “Information” button but in this case, we will be able to edit any of the attributes in our selected element. https://blog.gvsig.org/2014/12/10/gvsig-2-1-alphanumeric-editor-at-the-view/
Dyschromatopsia / colour blindness. From one View with a default legend, we can change it (or create a new one) to one which will be readable by users with any problem related to dyschromatopsia or colour blindness. https://blog.gvsig.org/2015/01/09/gvsig-2-1-dyschromatopsia-colour-blindness-extension/  22
 23 Memory management. RAM Memory management at the Preferences menu https://blog.gvsig.org/2014/11/19/gvsig-2-1-memory-management/
Derived geometries. It allows to create polygon o line layers from a point layer, or a polygon layer form polylines. The user can indicate which elements are part of each polygon or polyline. https://blog.gvsig.org/2014/12/10/gvsig-2-1-derived-geometries/  24
 25 MsExcel format supporting as a table. It allows to add Excel sheets as tables. https://blog.gvsig.org/2014/12/11/gvsig-2-1-from-excel-to-gvsig/
MsExcel format supporting as a layer. It allows to add Excel sheets as layers. For that, we will indicate the columns with the coordinates.
CSV support as Table. It allows to add CSV files as tables.
CSV support as layers. It allows to add CSV files as layers.
 26 Improvements in Table properties. The new properties window allows to the user to have all the information about the characteristics of the columns and be able to modify the representing way of the numeric fields. In addition to that, it allows to select the characteristic “Locale” of the table and to point easily which fields we want them visibles. Inside these fields, the “Geometry” filed has been added containing the coordinates of each geometry.
Table tools interface improved. Some changes have been for improving the user experience, such as adding buttons to work with the columns (add or remove) quickly from one table.
Linux 64bits support. There is a new Linux distribution for 64 bits, along the 32 bits one.
EPSG (projections) database update. The database has been updated with the addition of several new projections number, news for gvSIG.
Dragging layers from the file browser. It allows to drag files to our View from the file browser in our operating system and that gvSIG add them automatically. https://blog.gvsig.org/2014/12/01/gvsig-2-1-dragging-layers-from-the-file-browser/
Import / Export SLD legends. It allows to import/export legends to the SLD standard(Styled Layer Descriptor).
Field calculator new features. New features have been added, such as the function which permits to use the brackets in the expressions when they are not being used to indicate a field. For instance, “ [CAMPO1][:10]” would give us the 10 first attribute values . Some gvSIG 1.x features (rec, area or permiter) have been migrated..
New interfaces (create layer, export layer, info…..). The new interfaces have more options to create layers, export layers or ask for information of one element.  27
Scripting: raster data support. The raster data support has been included in scripting.
PostGIS connections and support. The tools related to PostGIS databases have been improved.
 28 POI Cities symbol library. An urban points of interest library has been added. https://blog.gvsig.org/2015/01/08/gvsig-2-1-symbol-library-of-urban-interest-points/
Geology symbol library. A Geology symbol library has been added, including a group of geological symbols in folders and subfolders (bedding, cleavage, eolian, fluvial/alluvial, foliation, geohydrology…) and a group of fill symbols with the RGB colour codes defined by the CGMW (Commission for the Geological Map of the World) representing the different stratigraphical unities. https://blog.gvsig.org/2014/12/09/gvsig-2-1-symbol-library-of-geology-2/  29
 30 Commerce symbol library. It contains a group of symbols related to business and commerce.
Military symbol library. A group of military symbols has been added defined by the standard APP6https://blog.gvsig.org/2015/02/13/gvsig-2-1-military-simbology/  31
 32 Collective Mapping symbol library. Symbol group orientated to the needs of social groups, to the collective mapping jobs and to analyse our social reality. https://blog.gvsig.org/2015/01/29/gvsig-2-1-symbol-library-for-collective-mapping/
Colors symbol library. It has different color scales to represent any kind of data.  33
 34 AIGA symbol library. It contains the symbols designed by the American Institute of Graphic Arts para transport.https://blog.gvsig.org/2015/02/12/gvsig-2-1-transportation-symbol-library-aiga/
Weather symbol library. Symbology to make climate maps according to the standard defined by the World Meteorological Organization.https://blog.gvsig.org/2015/02/02/gvsig-2-1-symbol-libray-for-climatology/  35

We hope you enjoy all the novelties of this version, that are here.

We hope 2015 is a year with a lot of novelties, where gvSIG 2.1 and the new website are the first of them. Be aware of them!

      Hola Manuel,
      No, no es posible debido a que la rama 2.x tiene cambios profundos en la arquitectura de acceso a datos, para mejorar todos los problemas de estabilidad de anteriores versiones.
