Reading or at least the overview of the latest manual dated QGIS is strongly recommended ([http://www.qgis.org/fr/documentation/manuels.html]).

<small>{{smalldiv|'' prerequisite'' Notions:

* The [[layer]] s QGIS work like [[Layer (computer graphics) | layers]] of [[Inkscape]];

* Highly recommended reading articles [[Tagged Image File Format]] and [[Shapefile]];

Line 32:

* With matrix as well as vector sources, you can create files via QGIS [[bitmap | matrix]] as well as [[image vector | vector]];

* Vector graphics consist of points, lines and polygons (and possibly polylines or relations).

{{smalldiv|''Anglicisms'': Matrix <nowiki>=</nowiki> * <nowiki>=</nowiki> bitmap raster vector ≠ <!-- <nowiki>=</nowiki> prevents "=" from being interpreted by {{smalldiv}} as a parameter -->

<small> ''Anglicisms'':

* Geographic marker <nowiki>=</nowiki> Geotagging <nowiki>=</nowiki> tag geolocation ≈ attribute (there can be no purely geographical data in attributes). QGIS supports these markers, unlike Inkscape.

Matrix = * = bitmap raster vector ≠

* Layer <nowiki>=</nowiki> layer <nowiki>=</nowiki> layer (layer is the literal translation of ''layer'' and was chosen in the translation of QGIS software. ''The term'' layer is perhaps more telling.)

* Geographic marker = Geotagging = tag geolocation ≈ attribute (there can be no purely geographical data in attributes). QGIS supports these markers, unlike Inkscape.

* Layer = layer = layer (layer is the literal translation of ''layer'' and was chosen in the translation of QGIS software. ''The term'' layer is perhaps more telling.)
