Geospatial data
To use a map, your data set must contain geographical data, such as countries, states, or provinces.
To determine whether a column can be used in a map, Cognos Analytics analyzes a sample of 2000 values in the location column, looking for recognizable place names. If 80% or more are recognized as map values, Cognos Analytics produces a map.
For example, you have four countries in your location column and one country is misspelled: Brazil, China, Indiea, and Russia. The typo for India means that only 75% of the values are recognizable place names and you cannot see a map as a starting point. However, if you have five countries and one has a typo in it, you see a map.
