Control of a map where the user can click and drag to select an area...Hi,
I'd need to find (or develop) a control of a map (worldwide if possible) where a user can click and drag to select an area by distance from the click point or using a square area (user's choice)... This control would return the postal/zip codes of the selected rectangle or the clicked point postal/zip code and the wanted distance range. Is it something that can be done in a web control? it's absolutely something easy (well, fairly easy) in a windows forms app, but how is it in web forms? I would probably have to use Atlas.... Is it something I can do using Javascript? will I have to make an ActiveX for it? Thanks ThunderMusic btw... I'd be interested in having some links to where I can find databases on worldwide postal/zip... I can't tell you how to map, as I have not gotten that far. I can give you
some info that may help. For mapping in .NET, there is a C# mapping project (open source) called SharpMap: http://www.codeplex.com/Wiki/View.aspx?ProjectName=SharpMap For the United States, mapping is generally done off of TIGR data, which is downloadable from the Census site (census.gov). It is a pain to download, to an extent, because there is no all in one download. It is GBs of data. Download a sample and go from there. There is also an open consortium of GIS mapping. Zip code data is for sale. While you can put together United States and Canadian zip codes by searching sites, it takes quite a long time to do and is only useful if your time is not worth anything. At work, we currently purchase US & Canada from Zipcodedownload.com. It is decent data and has a good price for a yearly subscription. This is NOT mapping data, however. -- Show quoteHide quoteGregory A.

At work, we currently purchase US & Canada from Zipcodedownload.com. It is decent data and has a good price for a yearly subscription. This is NOT mapping data, however. Newer maps than the Census cost lots of money. There are basically two companies that have data: NavTeq and TeleAtlas. Both price according to the type of application and tend to request monthly revenue streams for the data. It is worth it if you need accuracy on roads, etc., but not for a simple "find the zipcode" type app (TIGR should be fine for this). Hope this helps! -- Show quoteHide quoteGregory A.

note Cowboy's comments lead to the long and difficult task of doing it all yourself -- a rabbit hole of complexity and cost -- so it seems to me the easier choice is a design-build business model also called a mashup. That would mean using APIs provided by Google Earth and/or Microsoft Earth or Microsoft MapPoint or a similar service your control(s) interoperate with. Think of it this way. As an architect whose business process is "design-build" I would rent the heavy equipment and an operator to dig my holes, pour my concrete and so on. Google, Microsoft and others are now makig it possible to use or rent their heavy equipment to enable us to operate design-build businesses on the web. Your only other choice is to follow the rabbit hole. -- Show quoteHide quote<%= Clinton Gallagher NET csgallagher AT metromilwaukee.com URL http://clintongallagher.metromilwaukee.com/ MAP 43°2'17"N 88°2'37"W : 43°2'17"N 88°2'37"W "ThunderMusic" <NO.danlat.at.hotmail.com.SPAM> wrote in message news:OcxL3Po2GHA.4300@TK2MSFTNGP03.phx.gbl... > Hi, > I'd need to find (or develop) a control of a map (worldwide if possible) > where a user can click and drag to select an area by distance from the > click point or using a square area (user's choice)...

What I want to do with this is just something more graphical to work with for people to point out the distance range from one point to determine to which people their project will be presented to (it will be presented to people within this distance range), But right now, I can do fine with a country or a state/province/region or a city reference... But I was just planning for future features (dream list)... thanks a lot ThunderMusic "Cowboy (Gregory A.
