title: What technology is more reliable for web-based geotemporal data visualization?
body: <p>I have a PostGIS database with shipping tracks' data. It contains about 1 million points. Each 2D point has also a timestamp assigned.</p>
  
  <p>I need to plot these in a web-map visualisation tool such as OpenLayers or Leaflet for the users to be able to perform filtering and analysis of the shipping track data. This implies me adding a time slider like <a href="http://dwilhelm89.github.io/LeafletSlider/" rel="nofollow">this</a>, heat maps like <a href="http://esri.github.io/esri-leaflet/examples/visualize-points-as-a-heatmap.html" rel="nofollow">this</a>, custom selection of tracks to create graphs (e.g. speed vs time, etc), load/export cvs/sph data, etc.</p>
  
  <p>I have little experience in OpenLayers and none in Leaflet, although I'm keen to try new things. I'm just slightly worried about how Leaflet handles big amounts of data (if 1 million points in a map is considered "big"), and also concerned about how reliable it is for geotemporal data analytics, since it's still a tool under development and some of the things I might want in the future might not be there yet. OpenLayers has been here for longer, and it might be easier to find help and more examples.</p>
  
  <p>So what is most recommendable for my case, OpenLayers or Leaflet?</p>
