data of a project. Within each LOCATION, a mandatory "PERMANENT"
-MAPSET exists which contains projection information and some

-<h3>A) Create New Location with wxGUI</h3>
+<h2>4. Creating A New Location with the Location Wizard</h2>
The <a href="wxGUI.html">wxGUI</a> graphical user interface provides a
-graphical "Location Wizard" instead which let's you easily create a
-new LOCATION. You will be guided through a series of dialogues to
+graphical "Location Wizard" which let's you easily create a
+new LOCATION for own data. You will be guided through a series of dialogues to
browse and select predefined projections (also via EPSG code) or to
define individual projections. The rules to define the resolution as
described above also apply here.
-
-<h3>B) Create New Location with text screen</h3>
-Click on the "Create New Location" button, which will take you to a
-text screen on which you can enter a new location name, and then
-continue by pressing "ESC"-"RETURN" - i.e. press (NOT hold) the ESC key,
-and then press the RETURN key on your keyboard.
-
<p>
-Next you will need to assign parameters to the location such
-as the coordinate system and datum you want to use, the project area's
-boundary coordinates, and the default resolution for raster data:
+<i>Hint: You can create new location easily from a georeferenced data file.
+In this case you are asked whether the data itself should be imported
+into the new location. The default region is then set to match imported map
+and the GRASS GIS session is opened.</i>
-<ul>
-<li> Start by chosing between, X,Y, Latitude-Longitude, UTM, or
- "other" coordinate system. This choice depends on your data and the
- use you will make of it.</li>
-<li> You are then prompted for a single line of text describing the
- project area, for example "Topo Map of the Alps".</li>
-</ul>
-
<p>
-Next you are requested for some more information about the projection.
-Note that the prompts vary from projection to projection, an example follows:
+After defining new location, wxGUI starts automatically.
+If data were already imported, you can add them into the Layer Manager now
+and display them. If your location is empty you can import your data from
+the menu: Go to "File" -> "Import raster/vector data" (see also the
+related Wiki page on <a href="http://grass.osgeo.org/wiki/Importing_data">Importing data</a>).
-<ul>
-<li> (if you chose "D - Other Projection") "specify projection name":
- "list" gives you the list of all available projections, examples are
- "tmerc" for Transverse Mercator, "lcc" for Lambert Conformal Conic,
- "moll" for Mollweide, etc.
-<li> specify datum name: again use "list" to get a list of available
- datums, examples are "wgs84", "nad27", "eur79", etc.
-<li> Enter Central Parallel: 0 if you want the Equator as the
- central parallel
-<li> Enter Central Meridian: 0 if you want the Greenwich meridian as
- central meridian
-<li> Enter Scale Factor at the Central Meridian
-<li> Enter plural form of map units: for example, meters
-</ul>
-
-<p>
-The next step is the description of the project area's boundary coordinates
-and the definition of the default raster resolution:
-<p>
-The default raster resolution (GRID RESOLUTION) has to be chosen
-according to your needs. Generally, it is advisable to work in steps of
-0.25 (0.25, 0.5, 1.75, 2.00, 12.25 etc.). This resolution does not
-concern vector and site data since these are stored with their exact
-coordinate values. Note that every raster map may have its own
-resolution. You can leave this screen with "ESC"-"RETURN" and then
-if everything is correct accept the list of parameters that appears.
-<p>
-You will then be back to the startup screen to enter the mapset's
-name (if not already entered). Another "ESC"-"RETURN" will finally
-let you leave this screen. This mapset is created within the new
-location by answering "yes" to the next question. The mapset will
-use the parameters of the location (such as the region and resolution
-definitions) as its default parameters.
-<p>
-Now the project area, i.e. the location including a mapset, has been
-created. You have "arrived" in the GRASS system and can start working
-within this new location.
