Using latitude/longitude in Analyzer Report's Geomap

$

Dear everybody,

I have a database that contains institutions and their geographic location:

create table Institutions (
institution VARCHAR(255) not null,
institution_latitude FLOAT not null,
institution_longitude FLOAT not null,
impact INT not null -- some measure to
visualise
);

My intention is to visualise the institutions on a Geomap in an Analyzer Report of the Pentaho User Console. For this, I have created a Data Source Model in the Penaho User Console and have added a Property with Geography Type "Lat/Long".

The problem: My geomap does not show any institutions at all.

I am wondering therefore if there is any documentation available on how to configure the Geomap? Maybe even a tutorial with a simple example?

More precisely:



  1. Does the Geomap support showing data with lat/long coordinates? The Steel Wheels example seems to use names (and not coordinates) of places. Also, a post I have found seems to suggest that only certain names (or lat/long values?) seem to be supported – any clarifications would be welcome.
  2. How exactly does Geomap deal with hierarchies of places? The Steel Wheels example allows to drill into states/provinces and I am wondering how this is accomplished.


Thanks a lot for any pointers or suggestions!
Kaspar
