This is a discussion on Load/Render large number of pushpins within the MapPoint 2006/2009 Discussion forums, part of the Map Forums category; I need to work with a large number of pushpins (10000+). I'm wondering if anyone has any experience with FAST ...

Hi, ImportData method is fast for huge amounts of pushpin (1000 is a little less than a second on my machine). But wy loading 10000 pushpins ? Wy not load only the ones showed in view ? And depending on the zoom level eventually.

Thanks, I'll look into that! The plan is to load only the ones that are visible, however that may be 10000+. We don't yet know our clients exact needs, but I have the lucky job of trying to prepare for that possibility.  |

I agree with Wilfried. 10000 visible pushpins is overwhelming, to the point of being visually unusable. This is one of the reasons that MapPoint doesn't draw all roads at all zoom levels. You might wish to aggregate concentrations of pushpins until you are at a higher zoom level. Perhaps even use sized-circle mapping instead of pushpins? HTH Paul |

| Re: Load/Render large number of pushpins
I currently have a solution written that uses shaded data overlays per zoom level, however I have been asked to try and implement it by showing all pushpins. So although I agree it is visually overwhelming and not that useful, and also quite possibly to slow to be feasible, I still get to try! All feedback is appreciated though, thanks! |
