Hi, I kinda don't understand what exactly you want, but i will try. GeoModel is basically about saving latitude and longitude and then you can search over that information (using for example proximity fetch, which will give you the n closer points to certain point you define in terms of latitude and longitude)
Now, suppose you have information about certain places but in normal data, no latitude or longitude, just streets and city information. Then you can use for example Google Geocoding API ( http://code.google.com/apis/maps/documentation/geocoding/) to get latitude and longitude data for those points you have got, and then you can use GeoModel with that data. Then in order to use GeoModel, you just create a class and inherit from GeoModel. This new class can have all other additional information you need about certain point, but GeoModel gives you the "location" property and then you store the latitude and longitude. I'm not sure if that is what you were asking for.. maybe you mean something more advance about GeoModel but that's all i can spot from your question. I hope this helps!
