The QGis mapcolor files page already has some palettes you can copy, save as .qml, and use.. Save your first color style .qml file Done — section updated (2012/01). Copy-paste the following color code in an empty, plain text document (using something like Notepad or TextEdit), then save it in ./QGis/Mapcolors/ as Wikicarto_2.0.qml (the palette's name + .qml).
QGis (full name: Quantum GIS) is a GPL license, cross-platform (Windows, Linux, Mac), and rather friendly cartographic software application. It is a Geographic Information System (GIS) program you can use to create, view, and analyze maps.
> (better)QGIS 1.8 > Raster > Terrain Analysis > Shaded relief (the raster will be only the shade). It is necessary to enter a number as a "z factor". "z factor" may be 1 or a big number, like 10000 or 100000, in order to make a better relief. So, you have to try different numbers as "z factor".
Raster maps of environmental variables including soil pH, potential evapotranspiration, average snow depth, and more. Global 200: Vector data from WWF of "a set of the Earth's terrestrial, freshwater, and marine ecoregions that harbor exceptional biodiversity and are representative of its ecosystems."

QGIS supports raster, vector, mesh, and point cloud layers. [4] Vector data is stored as either point, line, or polygon features. Multiple formats of raster images are supported, and the software can georeference images. QGIS supports shapefiles, personal geodatabases, dxf, MapInfo, PostGIS, and other industry-standard formats. [5]
Georeferencing is crucial to make aerial and satellite imagery, usually raster images, useful for mapping as it explains how other data, such as the above GPS points, relate to the imagery. Very essential information may be contained in data or images that were produced at a different point of time.
Vector overlay is an operation (or class of operations) in a geographic information system (GIS) for integrating two or more vector spatial data sets. Terms such as polygon overlay, map overlay, and topological overlay are often used synonymously, although they are not identical in the range of operations they include.
In this case, some raster file formats allow a vector-like table of attributes to be joined to the raster by matching the ID values. [18] Raster representations of objects are often temporary, only created and used as part of a modelling procedure, rather than in a permanent data store. [20]: 135-137
