I'm wanting to do something with my application I have currently.
I currently have a bunch of events with names inside of places/venues
I'm wondering how I can get these places/venues to convert into lat/long for me to use elsewhere.
e.g. my data show I have Scarborough Open Air Theatre. How can I get the lat/long of this with only this bit of data?

It seems that the wikimapia API isn't working at the moment.
I'm wondering whether there's a way to obtain location data from wikimapia without using the API, e.g. by parsing the webpage source code.
For example, let's say I want to obtain the locations of the train stations in the northwest of Italy.
These can easily be displayed on wikimapia (by showing category "train station", category (tag) id 44751).
Can this information be extracted from the page linked to above without recourse to the API?
I was trying to display a MKMapView showing all the museums in a city. I haven't understood if this is a built in feature of the maps or I need to get the data somewhere else. Online I was seeing an example of government databases providing the information and location and then this was being added to the map. Does the map have this feature built in?
Nope, this is not built-in feature of the map (in apple map). But you have to make a filter (Query) that can fetch response what you needs (response will be in JSON format) and manipulate it in your map as a Annotaion.
I come here to ask you some informations or maybe help to try to do what i want.
Here it's what i want to realize:
I have a website and on it i have some places in database (with lattitude and longitude saved). I want allow users, when they click on a button, display a map with a marker on their actual position and others markers who will represent the places from the database near them.
I found some tools like google map API v3. With it i can show the user position but i don't know how i can display the position of the places store in my database.
If you have any ideas or examples.
Thank you.
(PS: Sorry for my english)
I built a similar app with Spring and Java. What you'll have to do is create Placemark JS objects and pass them to the Google Maps API. You can also pass a map size to determine the scope of the map returned to the user.
In order to determine nearby locations, simply build some ruby/rails code to limit the distance of locations from the user location.
Get user location
Determine which locations to show on map within your rails app
Pass desired placemarks to Google Maps (This can be found in API docs which are great)
Display the map returned by Google Maps on a view.
I think you could use geocoder gem for that:

I am trying to develop an iPhone app (with map routing function), and I need everyone's suggestions (guidance).
Below are a few specs:
The app will be running on iPhone with iOS 4+.
The app will have Map functionality.
In the app, given a "few locations" in a given order (to make things less complicated), the Map will draw routes between each locations on the Map.
Clicking on any location will display another page that shows some information about that location.
Can choose alternative route between two location (which I don't think is possible, but let me know if anyone know any framework that can do this).
I did some research, using Map on iPhone is easy using MapKit (and it's available after iOS 3.0). I followed this tutorial, and everything seems easy. However, if I want to draw routes on my map, I will need routes data in a CSV format. However, I do not have those data (yes! I suck).
And prior to iOS 5.1, MapKit use Google Maps, and I read somewhere that in Google Map's term and condition of use, it prohibit people from drawing on the Map (correct me if I am wrong).
In order to retrieve route data, I would imagine that I will have to get it through Google or Apple (I don't know if it's possible). I'm just wondering if Apple Map or Google Map have API to retrieve these?
If not, an alternative I came up with is to use a webview, and display my Map routes on Google Map. I'm just wondering if Google Map API will allow me to insert multiple locations and display all the routes?
I really need some suggestions... I am getting buried in all these problems.... thank you
Follow this sample - MKOverlay is the way to go. One more example is here.
I am developing an Android application that uses the geonames.org database. I only use the city/populated place category and their corresponding coordinates as provided by geonames.
I want the user to be able to provide his/her GPS coordinates and get a result back with the closest cities/populated places and their coordinates.
Even if the user is in a city I want that city's coordinates to be displayed along with the more distant ones.
Can this be done without the help of google or a web service? I might host the world city geolocations on my own server.
Thanks!
Since posting this I have found the answer to my own question. MongoDB supports geospatial indexing. Make sure that the longitude and latitude field is saved in one string and point the geospatial index to your loc: field. You can then perform queries with a bounding box to find closest locations within a certain radius for example. More about MongoDB geospatial indexing can be found here: http://www.mongodb.org/display/DOCS/Geospatial+Indexing
