RE: [flexcoders] Map Tile Library

[Kelly]

I tend to agree.   If the images and levels of detail available in yahoo maps suite your needs then using their component is by far easier then creating your own.   I am told they are currently working on a Flex 2 version of the map component.     --Kelly     From: flexcoders@yahoogroups.com [mailto:flexcoders@yahoogroups.com] On Behalf Of Igor Costa Sent: Saturday, October 07, 2006 9:43 PM To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] Map Tile Library   Man, just take  a look at the Flash Developer center of Yahoo! regards On 10/7/06, atlasalive <[EMAIL PROTECTED]com > wrote: I'm prototyping a map viewer application similar to Google or Yahoo maps. I will be connecting to image tile libraries that I create with another GIS application. So the one thing I know is that there will be a library of image tiles at different zoom levels and XML documents that communicate the metadata. These may be accessed directly or through a .Net web service. The server side will be .Net. All the tiles will be the same size. I'll need to implement standard map functions like zoom, pan, etc. I also want to do things like drawing polylines onto the map, overlaying icons, and the like. I'm new to Adobe Flex and I was hoping to get suggestions on an architecture. Basically 1) I need a high-performing system that retrieves the tiles and presents a seamless map to the user. 2) I would like to cache the edge tiles so the seamless effect continues when panning. 3) I'd like to be able to configure the application's number of tiles and tile size. 4) I'd like to make it flexible enough to draw tiles from a web service if necessary. 5) I'd like to deliver image tiles to the desktop separately and have the user 'point' to the local cache if possible. Apollo? Zinc? What visual components/techniques would best implement the seamless pannable tiled map? How does Yahoo do it? Any gotchas I should be aware of? What techniques /components will provide the optimal performance for accessing the tile libraries, either if they are files or web service calls? Are there existing bodies of work that I could use as a template? Are there mentors available who can help me up front? Anybody in the Seattle, USA area? -- ---------------------------- Igor Costa www.igorcosta.com __._,_.___ -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com SPONSORED LINKS Software development tool Software development Software development services Home design software Software development company Your email settings: Individual Email|Traditional Change settings via the Web (Yahoo!
