geolocation

I have to work with strings which may contain Lat/Long data, like this: $query = "-33.805789,151.002060"; $query = "-33.805789, 151.002060"; $query = "OVER HERE: -33.805789,151.002060"; For my purposes, the first 2 strings are correct, but the last one isn't. I am trying to figure out a match pattern which would match a lat and long separated by a comma, or a comma and a space. But if it has anything in the string other than numbers, spaces, dots, minus signs and commas, then it should fail the match. Hope this makes sense, and TIA! ^[+-]?\d+\.\d+, ?[+-]?\d+\.\d+$ The ^ at the start and $ at

All I want to do is find out the person IP address so that I can reverse geocode it to find out their latitude and longitude from which they are viewing my web site from. I can do that using Google ClientLocation API but it's unclear to me if I have to load the huge Google Map framework just to use it. Is it possible to simply use the ClientLocation API without having to load all of Google Maps? If so, how? Yes, you only need to use the ClientLocation object in the google.loader namespace so you need not reference the maps api or anything else. For example. <script src="http://www.google.com

Maxmind offers a binary DAT file format for downloading their GeoIP database. http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz Does anyone know how this has been packaged? Also, is there any kind of copy protection on the data? I'd like to offer up a set of data in a similar way. Anyone with any knowledge of this will receive my undying gratitude :-) It's just a proprietary binary format, heavily optimized for IP address querying. It doesn't have any copy protection. If you really want to reverse-engineer the format, take a look at the C# or Java API. I don't know if this

I am using the location manager's requestLocationUpdates() method to receive an intent to my broadcast receiver periodically. The system is correctly firing the intent to my receiver, and I have been able to use it correctly. The only problem is that the GPS location provider only stays active for a few seconds after the initial location acquisition, and I need it to stay on a little longer so that the location estimates are more accurate. My question is how to make the GPS location provider stay active for each periodic request that comes from the LocationManager requestLocationUpdates. Does

When I enter a screen, I check for if GPS is turned on, if not, the dialog to enable GPS is shown. When user clicks Yes, onActivityResult -> GPS is turned on and I try to get the location but this always returns null When I enter the screen with GPS already on, location is retrieved properly. I have been struggling with this for few days now and can't seem to find any resources.

Closed . This question needs to be more focused. It is not currently accepting answers. Learn more . Want to improve this question? Update the question so it focuses on one problem only by editing this post . Closed 5 years ago . Is there a way in rails via some mapping API/gem where I can define map areas/map zones (with polygon bounds) and detect if an address falls within a particular zone/area. This is easily done with geokit . First construct a polygon from LatLng: polygon = Geokit::Polygon.new([ Geokit::LatLng.new(0,0), Geokit::LatLng.new(10,0), Geokit::LatLng.new(10,10), Geokit::LatLng

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?
