Hi all, I am working on a project where I need to display and do cloropeth maps of around 10.000 polygons. I know Google Maps and Polygon is not up for that amount, the performance would be terrible.
I could use tiles, but I want interactivity when hovering over. Pretty much as the New York Times did for their census map (http://projects.nytimes.com/census/2010/map) As much as I can see the NYTimes I THINK is applying several techniques: 1) Streaming of polygon coordinates at different zoom levels (that sounds ok). 2) Using a Sprite as overlay to render the polygons so that panning still performs. (as defined in some techniques discussed 2y ago on the list) 3) Asynchronously adding the polygons so that when moving over a large area the drawing of the polygons do not kill the browser. what do you think? I am gonna start trying to produce something similar. Anybody has more ideas on what are they doing? And anybody has an implementation of a PolygonSpriteLayerOverlay that performs incredibly well? :) Thanks in advance for any tips, Javier -- You received this message because you are subscribed to the Google Groups "Google Maps API For Flash" group.
