Viewing PostGIS Layers using QGIS
Click the 'Add PostGIS Layer' button . This will open up a window.
layer : Alogical set of thematic data described and stored in a map library. Layers organize a map library by subject matter, e.g., soils, roads, wells, and extend over the entire geographic area defined by the spatial index of the map library.
Layer: The GIS data model represents the world by sub-dividing features on the earth's surface according to a specific theme. Each theme is georeferenced.
Layer - Distinct map theme. Usually a separate GIS file (TWS).
Light attenuation - Absorption, scattering, or reflection of light by water, chlorophyll a, dissolved substances, or particulate matter.
Layers: A logical separation of mapped data usually representing a theme, such as roads, political boundaries, etc. Layers are all registered to one another by means of a common coordinate system.
layer -- an integrated, areally distributed, set of spatial data usually representing entity instances within one theme, or having one common attribute or attribute value in an association of spatial objects.
layer
A thematic set of spatial data described and stored in an ArcStorm database or a LIBRARIAN map library. Layers organize a database or map library by subject matter (e.g., soils, roads, and wells).
Layer is a subdivision of a CAD or GIS database containing related data. Layers can be visualized as "transparencies" which allow the user to view and analyze information selectively by theme.
Layer A logical set of thematic data, usually organized by subject matter.
Library A collection of repeatedly used items such as a symbol library-often used graphic objects shown on a map-or often used program subroutines.
Layers - Refers to the various "overlays" of data each of which normally deals with one thematic topic. These overlays are registered to each other by the common coordinate system of the database.
layered complex An intrusive igneous body in which there are layers of varying mineral content.

Map layers are organized as a layer tree, in the window below the buttons. Layers can include raster and vector maps, text, map enhancements (scale and north arrow, grids, and frames), and commands (where any GRASS command be written).
map layers Spatial features of a particular type maintained as separate GIS datasets that can be combined in a digital map as if they were different maps laid over each other on a light table.
The layer model shown in Table 2 includes interactions that are purely technical, such as the exchange of data between systems.

The way maps and other data have been stored or filed as layers of information in a GIS makes it possible to perform complex analyses.
These might be represented as several different layers where each layer holds data about a particular kind of feature (e.g. roads). Each feature is linked to a position on the graphical image of a map.

Perhaps the most common is allowing the user to define a priority for data layers in combination with a tolerance value. Considering the soils and forest stand example the user could define a layer that takes precedence, e.g.
Conflation functions are used to ensure that common boundaries between different data layers share the exact coordinates.
