I access a webpage (eg "http://signal.eu.org/osm/#locs=40.853293,14.244461;41.312371,16.288605"), which shows a map control with details of a rail route. On that webpage there exists the map as a control. If I examine the map control using standard Edge functionality, I can see a series of coordinates. I would like to extract these coordinates for use in my VB.Net program. I can handle the desktop part, but the Webpage thing is all new to me. I have tried using a WebClient and downloading as a string, or using a WebBrowser and examining that object, but all I see is the main web page details and not the map control.
Any help would be really appreciated as I have just spent a few hours with google and I feel like I'm not really asking the right question.
If I understand correctly you want the direction of the map. So you want the step by step direction of how to go from "Via Matteo Renato Imbriani, Quartieri Spagnoli, Municipalità 2, Napels, Napoli, Campania, 80136, Italië" to "strada locale, Barletta, Barletta-Andria-Trani, Apulië, 76121, Italië"?
If this is the case, google provides an API exactly for that (Google for "Google direction API").

I am trying to embed an existing, public Google Map into a website. Specifically this one:
http://goo.gl/maps/cHf2
Of course I could use the iframe embed to achieve this, but I would like a little more control over the map … I imagined being able to pull all the markers from the map and display them as an index next to the map. Kind of like Google already does, but embedded in my page with my own styles and images.
I have been digging through Google, Stack Overflow and the API instructions and couldn’t find any relevant posts. In the GET string of the map on Google we can see this chunk:
&msid=212828439842926497866.0004bfae4da003d8ffd1f&mid=1341413217
I thought in there might be a maps ID and I could use it to query the content of the map through the API? The intention is using Google Maps as a CMS for less technical minded people and not dealing with geo data in our own CMS.
Any help would be greatly appreciated. Maybe I am just missing the forest for the trees.
You can download the kml that specifies the markers in that page and display that on your API based map. This example defaults to displaying it using geoxml3, but you can hide that and display the KmlLayer version.
You should be able to just point KmlLayer to the link (I downloaded the kml and put it on my server so it would work with geoxml3).
Here is an example (taken directly from the documentation) that does that

I'm using the Google Maps generator to create a few maps for a client. The maps embeded on the site are a bit small (255x176), so map real state is crucial. I've already removed the balloon, but can't find a way to remove the "Earth" view button from it (all newly generated maps come with it now, 4 views in total).
The annoying part is that the "Earth" view requires a Google Earth plugin to be used anyway, something the client could live without - me too.
Any advices there? Feedback will be greatly appreciated!
Cheers,

You may customize the map controls using the MAPS API.
Visit http://code.google.com/apis/maps/documentation/javascript/controls.html#DefaultUI
Look for MapTypeControlOptions and pass appropriate map type you want to show.
Refer http://code.google.com/apis/maps/documentation/javascript/reference.html#MapTypeControlOptions
http://code.google.com/apis/maps/documentation/javascript/reference.html#MapTypeId
If using the default UI, you would get only the map types in G_DEFAULT_MAP_TYPES, which does not include the Earth map type (G_SATELLITE_3D_MAP).
This means your generator is adding this map type explicitly. So you should be able to simply look for G_SATELLITE_3D_MAP in the javascript you get from the generator, and remove references to it.
If you are still having troubles, can you provide a link to the map generator you are using?
I have a map of several counties I need to turn into a county select menu (i.e clicking Leicestershire will select Leicestershire.
I am using a php built system that this map will need to return the appropriate value to. I am thinking this will be a get in the url, checked for valid values in the backend.
How would you approach this? A html co-ordinate map? Some sort of Javascript? Flash?
I am aware all those solutions have one drawback or another. Does anyone know a better way of doing this? Or an existing opensource project?
Just an idea, if I read your problem correctly: I would personally use the Google Maps API for this. Plot each county onto your custom Google Map, then when you click each marker an info window could appear with "Select this County". Click the link and pass a value through the URL to your PHP script.
Used a html map system. Dreamweaver made it easy (first time I've used the design screen seriously)
I currently have a map mashup that has locations that I'm populating from my own database. A few users would like to also show that map on their site(s). I'd like to give them the ability to do that, but would like to retain the actual functionality of the map on my own site: like add "stuff" to places on the map through my a web form on my site. I could open the entire API to allow them to create their own form along with the data points, but most of the people wanting to put up the map aren't developers, they are just enthusiasts that have put together a personal page that they want to spice up.
I was thinking I could just provide a JavaScript of some kind that they could then take to place on their site, or maybe an IFRAME of some type, or...any ideas? Anyone implemented this? TIA.
I haven't done anything like this myself, but I think your idea to utilise an iframe is on the right track. In fact, this is how Google Maps generates its embed code.
Your app will need to generate a URL with all relevant Google Map parameters such as bounds, zoom level as well as your application-specific params. Any event that triggers the map to re-draw (drag, zoom, etc.) will generate a new URL.
If you try the embed link in Google Maps as an example, it generates a URL that looks something like this:
http://maps.google.com/maps?f=q&source=s_q&sll=45.434035,12.339057&sspn=0.003294,0.004812&ie=UTF8&ll=45.432724,12.338966&spn=0.006588,0.009624&t=h&z=17
This URL can then be wrapped up in an iframe which your end users can place on their web pages.
Re: resizing
Yes, it's possible to dynamically resize it if width/height is part of your application params that generates the embed code. Again using Google Maps as an example:
<iframe
src="http://maps.google.com/maps?f=q&source=s_q&sll=45.434035,12.339057&sspn=0.003294,0.004812&ie=UTF8&ll=45.432724,12.338966&spn=0.006588,0.009624&t=h&z=17&output=embed"
width="(width-param)" height="(height-param)"></iframe>
If you mean resized by user, after it's been displayed, I'm not sure.. most likely, yes.
Well i want to upgrade contact page with dynamic map showing location and give oportunity to calculate route for comapny headquatters. Id it necessery for such simple task use Google api? i mean here generating akey etc? Fo i have any other alternatives to google maps?
There's really no reason to mess with the API at all unless you need to customize the appearance or behavior of gmaps. Why not just use an iframe with a url of:
http://maps.google.com/?q=[you-url-encoded-address-here]
or better yet, set up a textbox and a 'get directions' button to redirect that frame to:
http://maps.google.com/maps?saddr=[their-address]&daddr=[your-address]
edit: this works well in modal dialog if you don't want the google logo sticking out like a sore thumb in your pageflow
You could probably embed directly with a specific URL that will configure it to have the destination you want.
By the way, well written answers are much more likely to receive useful responses here.
You could consider http://www.openlayers.org/ as an alternative to google maps.
In fact open layers can be used to add a Google map, or an OpenStreetMap map or a Bing map, etc.
