| − | Importing data into a GRASS LOCATION

| + | |
| − | | + | |
| − | <P>
| + | |
| − | This Section gives an example how to import raster and vector data into the
| + | |
| − | alaska GRASS LOCATION provided by the QGIS alaska
| + | |
| − | dataset. Therefore we use a landcover raster map landcover.img
| + | |
| − | and a vector GML File lakes.gml from the QGIS alaska
| + | |
| − | dataset [[#label_sampledata]]</A>.
| + | |

| − | <OL>
| + | |
| − | <LI>Start QGIS and make sure the GRASS plugin is loaded.
| + | |
| − | </LI>
| + | |
| − | <LI>In the GRASS toolbar, click the grass_open_mapsetOpen
| + | |
| − | MAPSET icon to bring up the MAPSET wizard.
| + | |
| − | </LI>
| + | |
| − | <LI>Select as GRASS database the folder grassdata in the QGIS
| + | |
| − | alaska dataset, as LOCATION alaska, as MAPSET
| + | |
| − | demo and click OK.
| + | |
| − | </LI>
| + | |
| − | <LI>Now click the grass_toolsOpen GRASS tools icon. The
| + | |
| − | GRASS Toolbox (see Section [[node12.html#subsec:grass_toolbox|9.9]]) dialog appears.
| + | |
| − | </LI>
| + | |
| − | <LI>To import the raster map landcover.img, click the module
| + | |
| − | r.in.gdal in the Modules Tree tab. This GRASS module
| + | |
| − | allows to import GDAL supported raster files into a GRASS
| + | |
| − | LOCATION. The module dialog for r.in.gdal appears.
| + | |
| − | </LI>
| + | |
| − | <LI>Browse to the folder raster in the QGIS alaska dataset
| + | |
| − | and select the file landcover.img.
| + | |
| − | </LI>
| + | |
| − | <LI>As raster output name define landcover_grass and click
| + | |
| − | Run. In the Output tab you see the currently running GRASS
| + | |
| − | command r.in.gdal -o input=/path/to/landcover.img
| + | |
| − | output=landcover_grass.
| + | |
| − | </LI>
| + | |
| − | <LI>When it says <SPAN CLASS="textbf">Succesfully finished</SPAN> click View output.
| + | |
| − | The landcover_grass raster layer is now imported into GRASS and
| + | |
| − | will be visualized in the QGIS canvas.
| + | |
| − | </LI>
| + | |
| − | <LI>To import the vector GML file lakes.gml, click the module
| + | |
| − | v.in.ogr in the Modules Tree tab. This GRASS module allows
| + | |
| − | to import OGR supported vector files into a GRASS LOCATION. The
| + | |
| − | module dialog for v.in.ogr appears.
| + | |
| − | </LI>
| + | |
| − | <LI>Browse to the folder gml in the QGIS alaska
| + | |
| − | dataset and select the file lakes.gml as OGR file.
| + | |
| − | </LI>
| + | |
| − | <LI>As vector output name define lakes_grass and click
| + | |
| − | Run. You don't have to care about the other options in this
| + | |
| − | example. In the Output tab you see the currently running GRASS
| + | |
| − | command v.in.ogr -o dsn=/path/to/lakes.gml output=lakes_grass.
| + | |
| − | </LI>
| + | |
| − | <LI>When it says <SPAN CLASS="textbf">Succesfully finished</SPAN> click View output.
| + | |
| − | The lakes_grass vector layer is now imported into GRASS and will
| + | |
| − | be visualized in the QGIS canvas.
