Map Markers

Latitude/Longitude
Columns containing coordinates of point of interests (map markers) to be overlaid on the generated image. The appearance of the markers are determined by row properties and can be set with the according nodes (Shape-, Size-, Color Manager Node).

Map Polygons

Column
An optional column can be specified that contains the information how to relate the map markers (coordinates in the table at port 0). The column has to contain a list of row keys (strings) that can be created by using the 'RowID'-node followed by the 'GroupBy'-node.
The map markers (addressed by the row key) that are enlisted in one list cell are connected to a polygon in the given order and drawn on top of the open street map. Row keys that are not present in the table at port 0 are ignored.
The color and line thickness of the polygons can be specified by using the 'Color Manager'- and 'Size Manager'-node.
Fill map polygon
If the polygons to be drawn should be filled, just check 'Fill map polygon' (the line thickness has no effect than).
Show map markers
If not checked, only the map polygons will be drawn but not he markers.
