I found the prepare data function is very convenient to prepare geographical data based on city, country or coutry ISO code, I am also managed to integrated the autogenerated code in my load script so I can connect to my own table in Oracle. While I found it is very fast to plot points on the map, it is kind of slow (5-10 seconds) before coutries shown up on the map.
I checked data in coutryGeo.qvd file and found there are a lot of polygon data stored for one country, is there a way we can improve the performance? I think in most cases we will not need that much detail to display a country, but I do not know how to reduce the detail, any thoughts?
