Response found on from the MapPoint forum:


You have to decide if MapPoint is right for you. Keep in mind that 47,000 POIs you are reaching the upper limit of MapPoint. I think the max. number is 50,000. Make sure this list will not grow over 50,000.

You are correct, MapPoint is for finding your (finite number of) stores and showing them on a map, which is what most people want. As Steve mentions in his response, adding too many POIs can clutter the map to make the map useless.

Steve also insinuates that there are no applications that can do what you want. This is incorrect. There is a site that does exactly what you want. It is at www.geocaching.com. I helped design and deploy that site. MapPoint was not an option because they had in excess of 200,000 POIs and their users updated the POIs constantly.

Their maps display fast, no performance problems even when you request several thousand POIs and they are clickable without using a separate ?Client Point Drawing?. They implemented their POIs so they are ?always there?. Using an automated update and spatial index feature that actually builds the POIs layers right into the map and the map display. An innovative feature is that you can pan across to a new area and the POIs will appear. If you click on one, that software builds a new list below the map. The POI you clicked will appear on the top of the list and then ranks them in order based on distance. Mapping applications came from GeoMicro.
