Now, the mapmaker can collect precise GIS data from reliable sources and simply load them into QGis. Objects will be automatically placed in their exact coordinates, allowing the user to apply custom styles and output an accurate basemap, which may be the end product, or a background to host additional custom layers (icons, labels, a legend, etc.).
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.

Cylindrical In normal aspect, these map regularly-spaced meridians to equally spaced vertical lines, and parallels to horizontal lines. Pseudocylindrical
A common basemap, including current color leaf-off aerial photography and elevation data (LiDAR), reduces the cost of developing GIS applications, promotes data sharing, and add efficiencies to many state agency business processes. All basemap data acquired through this effort is being made available in the public domain. [14]
A GIS software program is a computer program to support the use of a geographic information system, providing the ability to create, store, manage, query, analyze, and visualize geographic data, that is, data representing phenomena for which location is important.
The Open Geospatial Consortium (OGC) became involved in developing standards for web mapping after a paper was published in 1997 by Allan Doyle, outlining a "WWW Mapping Framework". [4]
The framed version lines have no links, so it may be helpful to use a discrete label alongside a boundary (for example) to indicate what it is (See Banwen example, above). map-data-inverse will only work correctly with a boundary line that forms a complete circuit, and will layer a pale grey mask over the area outside of the designated boundary ...
