Registro de cambios para QGIS 2.2

Change log for the next release of QGIS 2.2.0. The emphasis on this release has been very much on polish and performance - we have added many new features, tweaks and enhancements to make the user interface more consistent and professional looking (and hopefully easier to use). The composer (used for creating print ready maps) has had a lot of work done to it to make it a more viable platform for creating great cartographic outputs.

Siempre que se agregan nuevas características a un software se introduce la posibilidad de nuevos fallos - si encuentra algún problema con este lanzamiento, por favor registre un boleto en el Rastreador de Fallos QGIS.

Aplicación y Opciones del proyecto

Característica: Soporte para la medición en Millas Náuticas

For you seafaring folks out there, you can now measure distances using nautical miles. To enable this, use the Settings -> Options -> Map Tools option panel.


Proveedores de Datos

Característica: Soporte para relaciones uno a muchos

This release sports the ability to define 1:n relations. The relations are defined in the project properties dialog. Once relations exist for a layer, a new user interface element in the form view (e.g. when identifying a feature and opening its form) will list the related entities. This provides a powerful way to express e.g. the inspection history on a length of pipeline or road segment. You can find out more about relations support here.


Característica: Herramienta de Exportación DXF

Se ha agregado una nueva herramienta al menú Proyecto para exportar DXFs


Característica: Pegar como nueva capa vector

It is a common activity in a GIS to create a sub-selection and then to create a new layer from the selection. In QGIS you can already do save selection as to save a layer from your selection, and now offers functionality that allows you to create a new file or memory layer from whatever is in your clipboard. Simply select some features, copy them to your clipboard and then do Edit -> Paste features as and choose either New vector layer or New memory layer from the submenu. The best part of this new feature is that if you have some Well Known Text (WKT) features in your clipboard from another app, you can simply paste them into QGIS as a new layer now.


Característica: gráfico leyenda WMS en tabla de contenido y diseñador

Prior to QGIS 2.2 the WMS data provider was not able to display a legend in the table of contents” layer list. Similarly no legend could be displayed in the map composer. QGIS 2.2 addresses both of these issues.

Clicking on the layer’s legend will open a frame with the legend at full resolution. The legend will display contextual information based on your current scale. The WMS legend will be shown only if the WMS server has GetLegendGraphic capability. Legend resolution can be modified changing Canvas & Legend options.



Función: herramienta de relleno digitado en anillo

This new tool is used to cut holes in polygons and automatically fill them with new features. If you hold down Ctrl when finalising the feature, the attributes will be taken from parent feature.



Característica: Expresiones recientes guardadas

El constructor de expresiones ahora recordará las últimas 20 expresiones usadas.


Característica: Pegar WKT desde el portapapeles

QGIS puede ahora pegar y crear un nuevo objeto espacial basado en WKT encontrado en el portapapeles. Simplemente copie algún WKT y péguelo en una capa editable. Puede también crear una nueva capa seleccionado Editar -> Pegar como -> Nueva Capa Memoria

Diseñador de Mapa

Característica: Mejoras para bordes de mapa zebra

Ahora puede establecer los colores del borde Zebra en el elemento del mapa en el mapa de impresión.


Característica: Soporte para rotación de elemento

Todo tipo de elemento en el diseñador de impresión ahora se puede rotar, incluyendo barra de escala, tablas y leyendas. Por ejemplo, puede rotar una etiqueta en el diseñador de manera que se ajuste mejor a su diseño de página (como se ilustra). Cambiar el tamaño de los elementos rotados también ha sido mejorada.


Característica: Adicionada escala en diseñado y mejoras de la regla

The appearance of rulers has been improved by adjusting the scale logic and by adding smaller ruler divisions, and by making vertical rulers use rotated text. There is also a new composer action for hiding/showing rulers. You can now quickly zoom to 100% page scale using the new Zoom to 100% tool on the toolbar. The composer window now lets you quickly switch the page scaling via a new scale combobox in the status bar. In addition a new indicator has been added to show you the precise pixel position of your cursor. The Close and Help buttons have been removed from the bottom of the composer window to give you the maximum amount of screen space for working with your compositions.


Característica: Generación de archivo World

In the composer you can now create georefenced maps! Simply ensure that you choose the correct map element in the Composition tab and then export your map as a PNG file. An accompanying world file will be written, allowing you to load your exported composition in QGIS as a raster layer.


Característica: Trabajando con múltiples elementos

Support has been added for moving and resizing multiple items simultaneously. You can now hold shift while resizing to maintain an item’s ratio while resizing, or hold control to resize from the item’s centre. Shortcut key also apply to moving items, so holding shift while moving an item constrains the movement to horizontal or vertical movement, and holding control temporarily disables item snapping. You can also hold shift while pressing a cursor key to shift all selected items by a larger amount.

Característica: Mejoras de atlas

You can now preview the individual pages of the map atlas that will be generated in composer. While in atlas preview mode you can output the current page without outputting the entire atlas. You can also tweak the map extent or scale for each feature while previewing the atlas page. Atlas map settings have been moved from the atlas panel to the map properties panel, so now more than one map can be controlled by the atlas generation. There’s a new option to automatically centre an overview map, which comes in handy when creating atlas based maps. More context information is now available so that you can adjust your symbology based on whether the feature is the current atlas feature or not. See this article for more info.


Característica: Selección de elemento mejorada

You can now select more then one item by clicking and dragging a box to select them, and there’s shortcuts for adding to a selection (holding shift while dragging), subtracting from a selection (hold control while dragging) and switching to «within» selection mode (hold alt while dragging). Shift clicking an already selected item will remove it from the selection. There’s also shortcuts and menu items for selecting all items, clearing a selection, and inverting a selection. It’s also possible now to select items which are hidden below other items by control-clicking an item, or by using «Select next item above/below» in the new composer Edit menu.

Característica: Mejor navegación de composiciones

QGIS 2.2 includes many improvements to help you navigate your compositions. You can now zoom in or out from a composition by using the mouse scroll wheel. A dedicated pan tool has been added which allows you to drag the composition around, and you can also switch immediately to pan mode by holding the space bar or the by holding the mouse scroll wheel. There’s also a new zoom tool which allows you to precisely zoom to a specific area of your composition. You can also switch to zoom mode at any time by pressing and holding control-space and drawing a zoom region on the composition.

Característica: Estilo mejorado de páginas y formas

You can now control the style of the composition background using the full range of QGIS” symbology options. It’s now possible to export compositions with a transparent (or semi-transparent) background. Shape items (rectangles, triangles and ellipses) can also be styled using the same options as polygon map layers. You can even style the page background or shapes by using data defined settings based on the current atlas feature! There’s also a new option for rounding the corners of rectangle shapes.

Servidor QGIS

Característica: Soporte WCS adicionado al Servidor QGIS

QGIS-Server already supports standards : Web Map Service (WMS version 1.3.0 and 1.1.1) and Web Feature Service (WFS version 1.0.0) and Web Feature Service with Transaction (WFS-T). With this new release of QGIS, you can now serve raster layers using the Web Coverage Service (WCS version 1.0.0)) standard.



Característica: Soporte para llenado de gradiente

The new gradient fill feature lets you create even better cartography than ever before. The feature has numerous options providing for great flexibility in how you apply gradients to your features. These include:

  • Rellenos de dos colores o basados en rampa
  • Origen basado en tela u objeto para sus gradientes
  • Gradientes que se originan en el centroide de la entidad
  • Tipos gradientes cónico, lineal y radial
  • Opciones definidas por datos (para usar una expresión o una columna de tabla) para todas las propiedades de gradiente.

Lea más sobre cómo usar rellenos gradientes aquí.


Feature: Label support for palleted rasters

Rasters that use a fixed colour pallette (typical for e.g. a land cover map) can now have category labels assigned which will be shown in the map legend and in the composer legend.


Característica: Las rampas de colores pueden ser invertidas

Se ha adicionado una nueva opción a los diálogos de simbología que tienen rampas de color para permitirle invertir la rampa de color cuando es creada.


Característica: Copiar y Pegar basado en representador

In the rule based renderer, you can now right click on a rule and then copy and paste the rule as a new rule.


Característica: Generalización de entidades al vuelo

QGIS 2.2 introduces support for on the fly feature generalisation. This can improve rendering times when drawing many complex features at small scales. This feature can be enabled or disabled in the layer settings. There is also a new global setting that enables generalisation by default for newly added layers. Note: Feature generalisation may introduce artefacts into your rendered output in some cases. These may include slivers between polygons and inaccurate rendering when using offset based symbol layers.


Característica: Puntos ancla pueden definirse para capas marcador

When defining symbology with marker layers (e.g. a point layer symbolized with SVG markers) you can now specify what part of the image should correspond to the “anchor point”. For example you can indicate that the bottom-left corner of the image should coincide with the position of the feature. You can also use the data defined properties to have this property set at render time based on an attribute in the data table for that layer (or an arbitrary expression).


Característica: Mapas temáticos basados en expresiones

Categorized and Graduated thematic maps can now be created using the result of an expression. In the properties dialog for vector layers the attribute chooser has been augmented with an expression builder. So now you no longer need to write the classification attribute to a new column in your attribute table if you want the classification attribute to be a composite of multiple fields, or a formula of some sort.


Característica: Soporte de expresión en diagramas de símbolo para tamaño y atributos

You can now use an expression to define the size and attributes when using the diagramming capabilities of QGIS. For more info see the Pull Request here Pull 1039


Característica: Regla Else en representador basado en reglas

The Rule based renderer now supports a ELSE rule that will be run if none of the other rules on that level match. Else rules can be nested just like any other rules.

Un ejemplo podría ser:

type = 'water' (style grey)
ELSE (estilo rojo)


Característica: Soporte de contorno interno para polígonos

Support has been added for polygon strokes to be limited to the interior of the polygon (so that it does not overflow into a neighbouring polygon).

More information on this feature can be found on the second part of this article.


Interfaz de usuario

Característica: Diálogos de propiedades mejorados

Todos los diálogos de propiedades han tenido sus menús principales actualizados para que se viera mas pulido, con una barra lateral de color inverso. Esto es puramente estético pero debe hacerlo más fácil saber cual es el contexto actual en un diálogo.


Característica: Mejoras en diálogo de expresiones

We have made some tweaks to the expression dialog - power users can now hide the operator buttons. There are also now splitters between the function list and function help areas, and between the expression and function list area. See the original pull request for details.


Característica: Nuevos keybindings

We have updated the keyboard shortcuts in QGIS to make it more efficient to carry out repetitive tasks.

  • ctrl-d - Elimina las capas seleccionadas en la tabla de contenido
  • > - Selecciona el próximo vértice cuando usa la herramienta nodo
  • < - Seleciona el vértice previo cuando se usa la herramienta nodo
  • Delete or Backspace - delete the selected features (you can undo these actions), or a node when using the nodetool.
  • F5 actualiza el lienzo (en vez de ctrl-r)
