Rangaggregasjon

Rangaggregasjon is a Norwegian term that translates to "range aggregation" in English. It refers to a process or method used in cartography and geographic information systems (GIS) to combine and display data from multiple maps or datasets into a single, cohesive representation.

In the context of GIS, rangaggregasjon can be used to aggregate data from different levels of detail, such as zoning or administrative boundary layers, into a single layer or map. This allows for the display of both high-level and low-level detail in the same map, facilitating analysis and visualization of spatial relationships between different datasets.

Rangaggregasjon can be applied in various domains, including urban planning, transportation, and environmental science. It enables the creation of complex and detailed representations of geographic phenomena, making it easier to identify patterns and relationships that may not be apparent at lower levels of detail.

The technique involves systematic aggregation of data from lower levels of detail into higher levels of detail, with the goal of creating a meaningful and coherent representation of the underlying geographic realities. While similar methods exist in other fields, such as statistical data aggregation, rangaggregasjon is specific to the spatial context and is commonly used in Norwegian geography and mapping applications.

Rangaggregasjon is not a widely used technique outside of Norway and areas with similar cartographic and GIS traditions. However, its application is expanding as a result of advances in digital cartography and the increasing availability of open-source GIS software.
