Pisteverkon

Pisteverkon is a term of Finnish origin that translates literally to "dot network" or "point network." It is used to describe a type of spatial data structure or visualization where individual data points are represented as discrete elements on a map or in a graphical display. This contrasts with methods that might use lines, polygons, or continuous surfaces to represent data.

In the context of geographical information systems (GIS) and data visualization, a pisteverkon often refers to the raw representation of locations or events. For example, the locations of individual trees in a forest, the addresses of customer households, or the epicenters of earthquakes could all be considered elements of a pisteverkon. The emphasis is on the discrete nature of each point and its unique spatial coordinates.

The term can also extend to abstract data representations where data is clustered or categorized into distinct points for analysis or display. When data is presented as a pisteverkon, the focus is often on distribution, density, and spatial relationships between individual items. This type of representation is fundamental for many types of spatial analysis, including density mapping, proximity analysis, and the identification of clusters or outliers. The visual output of a pisteverkon is typically a scatter plot or a series of markers on a map.
