I am building an online reservation system for a tennis club and I want to visualize our member count on a map of Belgium with a count per district/village or city (whatever is possible).
How should I do this?
I thought using something like Google maps?
You can use Google Map Layers. But then, it depends on what kind of data you have.
You could for example use OpenStreetMap with custom markers. The same functionality is provided by google maps.

As a newbie I'm making a Java desktop application based on OpenStreetmap, jXMapKit library.
What I have actually done is displaying map and possibility to center possition by typing X and Y coordinates.
Moreover I would like to display/load on my map some places like: cinema, theater etc. but I don't have any idea how to do it.
Is there any chance to download some list of places from any website and display it on my app?
Regards
Take a look at Overpass API. For downloading specific POIs you need to know their key-value-pairs. For cinemas this is would be amenity=cinema. Also take a look at overpass-turbo. This is a webfrontend for Overpass API and allows you to play around with your queries and to visualize the results.
Me and My group are doing a Map project for my University Campus. we considered using google maps and its directions apit to do building to building and user location to building and eventually room to room. the problem is that because the paths on our campus are not mapped so unless we do manual routes and that would take to long. is there any alternative map/directions Api that we anc use that woudl just as well?
see this top-10-mapping-apis and this Comparison_of_web_map_services
i suggest u to use mapquest.
I am very new to Android development. I am converting my iPhone app to Android. In my iphone application, I used NSMutableDictionary to store StudentName(Key) and StudentId(Value) from NSXmlParser. Because, each student have different id, each id have different details for the student. If the user search the StudentName using UISearchBar, I want to show the StudentName and also to retrieve the correct Id for that student. I want to do the same in Android app. I searched my level best in Google for this but, I can't find the exact solution for my problem. Can anyone please help to find out the solution?
Thanks in advance.
It sounds like you probably want a HashMap... that's certainly a mutable key/value dictionary. It's not clear what you're doing with NSMutableDictionary, but if it's simple key/value lookup, then some implementation of Map (whether it's HashMap or something else) is appropriate.
You might want to read the Java Collections tutorial, too.
I want to draw a cluster graph like this. Is there a library for this? How should I build the data structure to contain the input data? Like a dictionary with key as the node itself and value as an array with the nodes connecting to. What could be a more precise term to describe this?
Try a library like JUNG.
JUNG is a framework made for displaying and working with any kind of graphs and networks on Java. It supports transitions, collapsing, complex layouts, …
About the data structure: It is complicated, and depends on the type
of cluster (bidirectional or unidirectional).
In the last case, you shouldn't use a Dictionary,
or connections would be stored twice.
Look at JUNG, for example. I think its data is Serializable.
Take a look at JGraphT: it provides the data structures and you can then render that using JGraph.
For my CS bachelors I am doing a Senior project using android and google maps.
My vision was to do a (relatively) simple Dijkstra shortest path using google maps road data. I was going to add elevation change along with 2D distance. I am doing well playing with maps in android but I am completely stumped trying to access google maps data in any sort of searchable form.
How would I go about accessing the data for say intersections of roads (lat/long) in a particular area?
There has to be a way to pull that data in some sort of tree form. It seems like it may be possible with kml?
Any pointers would be awesome.
I want my paths to follow roads but If i cant this is going to turn into an orienteering application fairly fast.

You might want to look into http://www.openstreetmap.org/ instead, they have the lat/long points of streets available for view. Google and others buy theirs, which keeps you from being allowed to access the raw information.
I don't believe you can access raw road data from Google Maps (such information is very valuable - if Google gave it out for free I can see car navigation companies going bust!). The best you can do is get the end result.
