h1. Introduction 

Quantum GIS (QGIS) is a user friendly Open Source Geographic Information System (GIS), licensed under the GNU General Public License, that runs on Linux, Unix, Mac OSX, and Windows. QGIS is Open Source software and its free of cost. It supports vector, raster, and database formats (including the most common ESRI ShapeFile and geotiff). QGIS supports a wide variety of plugins to do things like display tracks from your GPS, and much more. They can be easily managed through the Plugin Manager.

As an open source project, we provide support for using QGIS via our mailing lists and bug tracker:
 - For general enquiries subscribe to our users mailing list at
 - For developer related enquiries subscribe to our separate developers list at
 - If you think you have found a bug, please report it using our bug tracker. When reporting bugs, please include some contact information in case we need help with replicating your issue. The tracker is available at

% QGIS 1.20 brings with it a wealth of improvements, $NBUGS bug fixes and many new features. 

Along with the release of QGIS 1.2.0, the QGIS Community Team is also extremely pleased to announce the immediate availability of the QGIS Users' Guide version 1.2. 

%This is a substantial body of work that includes a complete revision of the guide, addition of many new sections covering the user interface, introductory tutorials on programming with QGIS, notes on compilation, and much more! The guide includes many screenshots to make it easy to digest. Work will soon begin in translating this guide into additional languages. In all the QGIS User's Guide includes over 250 pages of content and is a fantastic companion to the QGIS 1.0.0 application. 

The guide can be downloaded from

% [NOTE] shall we keep the line below? only 16 bugs have been fixed, but someone could be interested

Let's take a deeper look at what's new in this release...

h2. Editing 


Editing functionality in QGIS has had a major update in this release. This includes the addition of new vector editing tools:

 - delete part of multipart feature 
 - delete hole from polygon 
 - simplify feature 
 - Added a new "node" tool (in advanced digitizing toolbar). 
 - New functionality for merging features 
 - Added undo/redo functionality for vector layer editing. 
 - Added option to show only markers of selected features in editing mode. 
 - Change layer's icon in legend to reflext that the layer is editable.

In addition, there are undo/redo actions in Edit menu, in Advanced digitizing toolbar and there is a new dock widget displaying undo stack of active layer.

About the node tool: It resembles a tool for editing paths by nodes that is present in every vector editor. How does it work (in QGIS)? Click on a feature, its nodes will be marked by small rectangles. Clicking and dragging a node moves it. Double clicking a segment will add a new node. Pressing delete key will remove active node. It's possible to select more active nodes at once: by clicking and dragging a rectangle. It's possible to select a segment's adjacent nodes by clicking on the segment. It's possible to add/remove active nodes by using Ctrl when clicking a node or dragging a rectangle

We recommend that you turn off vertex markers in QGIS options when working with this tool: the redraws are much faster and the map is not cluttered with markers.

h2. Plugins 



 - A new OpenStreetMap provider and plugin have been added to QGIS!
 - The order of layers in the WMS dialog can now be changed. - The eVis plugin, version 1.1.0, has been added to the QGIS project and included as a standard plugin. More information about eVis can be found here: .
 - The interpolation plugin now has the ability to use line layers as constrains for triangulation in interpolation plugin. You can also now save the  triangulation to shape file.

h2. Keyboard shortcuts 

New feature: configure shortcuts for actions within main window of qgis! See menu Setting->Configure shortcuts

h2. Map Composer 

It is now possible to lock/unlock composer item positions by right mouse click. The width and height of the composer map will now remain fixed if user sets the composer map extent to the map canvas extent. possibility to display current date in composer label by typing (d 'June' yyyy) or similar. It is now possible to keep the current layers in a composer map even if further layers are added to the main map. Export to PDF in composer is now possible.

h2. Attribute tables 

It is now possible to search the attribute table within selected records only. General speedups have been made on the attribute table. Setting of field width and precision when adding attributes is now possible. Handling of attribute types in WFS provider has bee improved.

Attribute aliases for vector layers are now available. The aliases are shown instead of the original field names in the info tool and attribute table to make things easier for end users. There is now a GUI for setting edit widgets for layer attributes. A new dialog allows loading a value map from a layer (could be non-spatial table too!). The edit widgets settings will also now be respected in the attribute table.

h2. Projects Management 

QGIS now includes support for project relative position of file data sources and SVGs. The saving of relative paths of file data sources is optional.

h2. PostGIS & the PostgreSQL Provider 

You can now select the SSL mode when adding a new DB connection. Turning off SSL encryption can greatly improve performance of PostGIS data loading where connection security is not required. Support has been added for more native types and for setting of column comments.

h2. Symbology enhancements 

 - allow refresh of symbols via popup menu on the renderer's symbol selection 
 - add support for data defined symbol(name)s 
 - add support for font symbol markers (only data defined - no gui yet) 
 - add symbol size in map units (ie. symbols that keep the size in mapunits independent of the mapscale)

h2. Command line arguments 

Added command line argument support on Windows. Enhancement of command line arguments: 
 - allow given snapshot sizes 
 - allow suppression of splash screen 
 - capture map decorations from plugins on snapshots
