Hello,
I don't know of any tutorial, but, maybe we can help.
Atlas generation allows you to, for one single map in your print composer
map, create a set of similar maps, but with different extents,
labels\titles and even
images<http://nyalldawson.net/2013/04/a-neat-trick-in-qgis-2-0-images-in-atlas-prints/>(e.g.,
a company logo). All this dynamic info must be in a already loaded
layer.
Lets say you need to make a map for each of your municipality's green
parks, having a layer with each park boundaries and it's name.
- Start by preparing a map like if it's for a single park in the print
composer. Add a map, a title or two, a legend and so on.
- Then go to the atlas generation tab, tick the "generate atlas".
- In composer map choose your main map (if you only have one generally its
map 0),
- For coverage map select your green parks layer.
>From now on, when you try to output you map in any format (Print or
export), QGIS will iterate over your Green park features, zoom or pan your
map to each, and produce a individual output (a file or a print) for it.
Of course various configurations can be made to fit your needs, like choose
if you want a fixed scale or a zoom to each feature, change each map title
with the green park name field.
Like explained in the user manual, you can also use any of the coverage
fields in your map labels.
Hope this helps,
Alexandre Neto
