First is to enrich model with geospatial dimensions to consume geomaps

SAC supports latitude/longitude coordinate systems

Wave 2019/07 – able to enrich geo with names in English or ISO codes (presents names, territories)

Bubble Layer is useful with 2 measures

Point of Interest Layer – created separately (does not require a geo enriched model), available in SAC repository

Heat map – look at density of information, data points

Chlorpleth – also known as drill layer – can consume hierarchy data – drill down from country to region to data points, supports geographic shapes

Feature layer allows you to access publicly available maps such as Esri ArcGIS service; no model needed

Flow layer – analyze movement of information between 2 geographic data points
