After this introduction to data sources, we can create our first map. We will build the map from the bottom up by first loading some background rasters (hillshade and land cover), which we will then overlay with point, line, and polygon layers.
Let's start by loading a land cover and a hillshade from landcover.img
and SR_50M_alaska_nad.tif
, and then opening the Style section in the layer properties (by going to Layer | Properties or double-clicking on the layer name). QGIS automatically tries to pick a reasonable default render type for both raster layers. Besides these defaults, the following style options are available for raster layers:

Paletted: This style is used if a single-band raster comes with an indexed palette.
Singleband gray: If a raster has neither multiple bands nor an indexed palette (this is the case with, for example...
