[flexcoders] GIS and Flex
Hi All, Does anybody have idea how to implement gis(geographyical information system) in flex with the gis data in it. What kind of gis data format files the flex requires so that i can retrieve the data and display it in the UI. Thanks Bollywood, fun, friendship, sports and more. You name it, we have it on http://in.promos.yahoo.com/groups

I think they have some cool api to let you display GIS data in your Flex apps. Also, have a look at mapquest (http://www.mapquest.com) Another solution is to use yahoo or google maps. I don't know how that works, so you better wait for someone to reply to that. All the best, Fidel.

What kind of gis data format files the flex requires so that i can retrieve the data and display it in the UI. images. esri shapefile. SVG (maybe via degrafa).

You can use the ESRI, yahoo, mapquest, google, etc map APIs. You can also read the ArcView Shape files and associated DBF files using this library and create your own components. http://code.google.com/p/vanrijkom-flashlibs/ I started with that library to create a heat-map component using maps. The problem with embedding or even downloading ArcView shape files is their size - even the US is over a meg. The problem is that shape files just store points and there are a great number of points. You can reduce the size by storing in your own format (a fixed width integer is half the size of a floating point number). I did that plus ran some map simplification algorithms to reduce the number of points and ended up getting even a world map down to under 100K. Sadly I cannot share the code (it was done for hire).
