Hi everybody, I'd like to develop an iPhone app that must that locate the user in a museum then popups some useful information about the sculpture he is looking at. Thus, these questions came to my mind: How accurate are the longitude and the latitude values ? Because I want to give to each place in the museum this couple of values s...
Hi, I've got a latitude/longitude value.... How can I search and get the city? ...
My goal is to be able to open a web page on a mobile browser and, provided you are within the geographical bounds of the mapping area, plot your location on a stylized map image (PNG, JPG, whatever). Also on this map will be points of interest, and it would be nice to say "You're closest to XZY thing". Is it sufficient to gather individ...
I'm trying to put a Google map in my page and make it so that when the page loads the map will display exactly the location of the user. In order to do so, I've taken the google maps API code and inserted it into my HTML5 page. At first the browser did ask for permission to share my location but it isn't actually showing this location on...
I was wondering how and where companies like Foursquare/Gowalla find and keep up to date their list of location/businesses. Is it a web service? Do they buy a directory and enter it into a database? ...

I have a web application that has a configuration folder that houses multiple XML files that are configuration settings for multiple "portals" as you will. I need IIS to have access to them so the "portal" loads (sql connection strings, master page paths) but I want to deny any outside access (url browsing). Here's an example below: h...
I'm looking for a mapping API something which has similar functionality to Google-maps but which perhaps has something along the lines of the Apache / MIT license. I basically want to plot points on the map. Does such a thing exist? If so are there any guides to plotting points on this map API? ...
See this description? "The ZoneTag client runs as a background process, monitoring the cell tower to which the phone is currently connected (which provides a rough location) and possibly communicating via BlueTooth to a GPS device, providing much more exact location information (and also providing a mapping between cell tower and physic...
I'm new to OpenStreetMap and I've been browsing the wiki and the net and I can't seem to find a tutorial anywhere but I've seen examples on the net. Basically I want to generate my own OpenStreetmap and plot markers taking the latitude and longitude from a MySQL database and plotting them on my map. When the user clicks on a mark I'd l...
I can't seem to find much documentation on this. What's the simplest way to create a database/table on postgres supporting a query like this SELECT * FROM table WHERE distance(POINT(0,0), table.location) <= 1000m; Where POINT(0,0) and table.location should be latitude/longitude pair, and 1000m is 1000 meters. And how should I go about i...

I have looked on the web and found you can use a Google API but there must be an Apple function somewhere to handle this? I have come accross the MKReverseGeoc...

Here is the code that I use and it works. The problem is sometimes it does not give me any location sometimes it does. Android Manifest permissions I am using. <...
Given a starting point (origLat, origLon), ending point (destLat, destlon), and a % of trip completed. How do I calculate the current position (curLat, curLon)? ...
I want to build a location based app, so naturally I am going to write my app using an existing API. But I am not sure what the pros/cons of developing on top of Foursquare (or Gowalla) vs Facebook Places. Note: this is not intended as a political debate "which service is cooler/better/sexier/whatever" but a true concern as to the pros...
