Before you perform geospatial analysis in stories, you must first import coordinate data and enrich it in the modeler. This process creates a new column in the data view with an enriched format of latitude and longitude coordinates.
NoteGeo enriching is available for both live and replicated data scenarios; however, in this course we’re focusing on the replicated use case.
As a prerequisite, you must have an XLSX or CSV file with a location ID column that contains unique data, and latitude and longitude columns.
A Location dimension is created in the modeler using location data. This acts as the foundation for the map in your story. There are two ways to geo-enrich your data:
- By coordinates: Geo-enriching your data by coordinates enables you to use longitude and latitude coordinates. Your data may already include this information, but you can also enter it manually in a file. These coordinates are used to create a map anywhere in the world.
- By area name: During the creation of the Location dimension you can download all the currently supported countries, regions, and sub-regions. This option doesn't support an area enrichment with mixed granularity. For example, if enriching an area that has locations in both Country A and Country B, but Country A doesn't go down do the Sub-Region level, then the enrichment can only be created to the Region level at the lowest.
The following Geo by Coordinates dialog shows how you can enrich your data by coordinates.
