QGIS displays raster or vector data in the projection you have him before indicated. To choose a projection to your project, QGIS 1.8 > Preferences > Project Properties > select the desired projection in the list. When you import your raster and vector layers in the current project, they should be displayed directly in the right projection (but ...
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.
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.
In progress Need QGIS 1.8. According to this recent post and its comments : > QGIS 1.8 > Raster > Terrain Analysis > Relief (the raster will be relief + shade, unfortunately colors will be discrete and not smooth) or > (better)QGIS 1.8 > Raster > Terrain Analysis > Shaded relief (the raster will be only the shade).

Version 1.0 was released in January 2009. [8] In 2013, along with release of version 2.0 the name was officially changed from Quantum GIS to QGIS to avoid confusion as both names had been used in parallel. [9] Written mainly in C++, QGIS makes extensive use of the Qt library. [6] In addition to Qt, required dependencies of QGIS include GEOS and ...
[3] The user provides a tolerance distance, and as the lines of the input layers are being combined topologically, any lines that are roughly parallel, consistently closer together than the fuzzy tolerance, are combined into a single line. The choice of a proper fuzzy tolerance depends on the situation, especially the scale of the data, and can ...
To demonstrate specificity Inheritance Inheritance is a key feature in CSS; it relies on the ancestor-descendant relationship to operate. Inheritance is the mechanism by which properties are applied not only to a specified element but also to its descendants. Inheritance relies on the document tree, which is the hierarchy of XHTML elements in a page based on nesting. Descendant elements may ...
