View Geometries as Map

Displays one (or two) table(s) made of spatial features on a map.

Input data should contain a "the_geom" column encoded in WKT (Well-known Text) representation, and a variable storing the Coordinate Reference System. The best is to display data which was loaded using the "Read Shapefile as WKT" node.

Once you are in the the view:

wheel scrolling zooms in and out
the "Spatial tools" menu provides "zoom to fit", zoom in and out, info or pan (move) features

You can color the geometries by tuning the default colors in the configuration pane. You also can use the color manager node, and assign colors to each line based on its characteristics; this leads to more interesting symbologies.

The actual visualization is done using the wonderful geotools library.

Options

top table: default color: The color to use if there is no color assigned to each line
top table: opacity: Opacity of the geometries of the first table. Keeping a bit of transparency is good (defaults to 0.7), as it helps to detect overlapping geometries.
bottom table: default color: The color to use if there is no color assigned to each line
bottom table: opacity: Opacity of the geometries of the first table. Keeping a bit of transparency is good (defaults to 0.5), as it helps to detect overlapping geometries, and enables to views the geometries of the first table below.
WMS server for overlay: The server to load the background overlay from. Change in case the overlay is not displayed.
