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.)

Import files using the buttons described below. Each layer imported into QGIS contains a data type (points, lines, polygons). ''Note'': a [[OpenStreetMap]] (specific button) extension .osm corresponds to three layers (points, lines, polygons)..
