1. Add a Vector layer, 2. Add a Raster layer, 3. Remove Layer(s). 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)..
1. Add Vector Layer, 2. Add Raster Layer, 3. Remove Layer(s) Loading a GIS file adds the data into your project as a layer. For our purposes, we care about vector layers and raster layers. There are three ways you can add layers into your project: using the menu, using the keyboard shortcuts, or using the toolbar icons.
The PDF format is widely accepted and is considered the de facto standard for printable documents on the web. This means that users do not require the any proprietary plug-in to read geospatial PDFs created following the PDF 1.7 specification, which was published as ISO 32000-1 standard . [ 3 ]
To merge vectors layers there is a similar pathway from QGis (1.6) > Vector. However, vector being light, it is usually not necessary to merge them Last, for vector to merge with raster, vector layers can be converted to raster before to be merged with raster base map, and for raster with vector, raster base map can be converted to vector to be ...
In cartography, a Styled Layer Descriptor (SLD) is an XML schema specified by the Open Geospatial Consortium (OGC) for describing the appearance of map layers. It is capable of describing the rendering of vector and raster data. A typical use of SLDs is to instruct a Web Map Service (WMS) how to render a specific layer.

Keyhole Markup Language (KML) is an XML notation for expressing geographic annotation and visualization within two-dimensional maps and three-dimensional Earth browsers. KML was developed for use with Google Earth, which was originally named Keyhole Earth Viewer.
