What does the GeoMakePoint function do?

The GeoMakePoint function is specifically designed to combine longitude and latitude values into a spatial representation known as a point. This function is essential in geographical data visualizations, as it allows the user to create geographic coordinates that can be rendered on a map within Qlik Sense.

By using GeoMakePoint, you can effectively take two separate pieces of numerical data – the longitude and latitude – and merge them into a single geographic point. This capability is vital for any application where geographical data needs to be analyzed, displayed, or visualized, such as mapping customer locations or tracking deliveries.

In contrast, other options do not pertain to the functionality of the GeoMakePoint function. Calculating total records relates to aggregating data, while returning a field's previous value and scripting for subroutines address different programming functionalities unrelated to geographical data assembly. Therefore, the correct choice highlights the specific purpose of the GeoMakePoint function in handling longitude and latitude data efficiently.
