Line 44:

You are now working with QGis, your GIS data—namely, ETOPO1—and your customized palette. To output your first topographic background, '''don't use ''File > Save as Image'', which is a simple screenshot.''' For better quality, use the ''SimpleSVG plugin''. <!-- This step will walk you through outputting a map like the one you see on the right, including a grid and an inset that lets the viewer know where in the world this section is located. -->

;Install the "SimpleSVG" plugin

;Background

:QGis (1.7) > Plugins > Fetch Python plugins > (a window pop up)

:>>Repositories tab > Add 3rd party repositories

:>>Plugins tab > Filter : type "SVG" > "SimpleSVG" plugin appears > select > Install plugin.

;Run SimpleSVG plugin (when installed):

# Open SimpleSVG plugin (when installed): QGIS (1.7) > Plugins > Save as SVG > Save as SVG''.

;Tips

# To give a smooth, gradient-like appearance to the colors, go to ''Layer > Properties > Colormap > Color interpolation'' (at the top), and set it to '''''Linear'''''.

# By default, the canvas of QGIS (geographic area visible in QGis) will become the area printed out.

# Open SimpleSVG plugin (when installed): QGIS (1.7) > Plugins > Save as SVG > Save as SVG''.
