<h3>Project Properties</h3>

This dialog allows you to set a number of properties related to the
|
|
<label>Project</label>. A Project is a saved set of layers and their settings,

as well as other information required to restore the project from disk.

<h4>Coordinate Reference System (CRS) Tab</h4>
|
|
</a>
|
|
|
|
<p>
|
|
The Coordinate Reference System (CRS) tab allows you to set the projection for
|
|
the current project and enable on the fly transformation. You do not need to
|
|
have a saved project to setup and enable 'on the fly' CRS transformation.
|
|
</p>
|
|
<p>
|
|
To use 'on the fly' CRS transformation, click the <label>Enable 'on the fly'
|
|
CRS transformation</label> check box. Then choose the projection for the
|
|
project (map canvas) from the list of Geographic or Projected coordinate
|
|
systems.
|
|
</p>
|
|
<p>
|
|
You can find a coordinate system by entering its name, EPSG code or the QGIS ID
|
|
into the <label>Filter</label> text field. The list of recently used
|
|
coordinate systems are available at the top for quick access.
