Hi All, Alright so I could probably write a novel about the background of the info/feedback I am actually looking for but I think the easiest thing to do is just put some basic info out there and respond to questions that people have.
I'm working on a prototype map (http://dev.wt360.com/Maps/Interactive) that will: -allow users to overlay one variable at a time -have an arbitrary # of time periods that can be looped via controls on the page -allow a user to dynamically adjust the opacity of the overlays -only display tiles for 4 zoom levels The sandbox version I linked to above is REALLY rough, so don't judge me; not all variables work ATM :) Also, pretty much all the google maps related JS is in http://dev.wt360.com/js/maps-interactive-v3.js. The way my process works is that - when a user requests a variable - it creates a new overlay, or overwrites if one already exists at a given index file, for each time period that variable contains. Since there can be as many as 15-16 periods for a given variable, the result is lots and lots of tiles. Once all tiles are loaded things are surprisingly smooth as far as the animation but it can get ugly if a user requests a new variable and tries to start the loop right away. So there are 2 questions that I have: 1) Is there a better (performing) way to accomplish this? 2) Is there a way to somehow force the tiles needed for the existing viewport to load for all overlays/periods before starting to pull "nearby" tiles for overlays/periods whose viewport tiles have already loaded. Ok that made no sense. Let's say I have 3 time periods. The flow I am looking for is: -load viewport tiles for period 1 -load viewport tiles for period 2 -load viewport tiles for period 3 -load nearby tiles for period 1 -load nearby tiles for period 2 -load nearby tiles for period 3 I'm assuming that the API already does this but my implementation is just garbage. It could also just be that my end goal for all of this is overly ambitious and attempting to load 256x256 tiles for 15-16 periods w/any sort of reasonable performance is simply the very definition of insanity. Thanks in advance for your help. -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
