geolocation

This is a followup to this question . I seem to be stuck on this. Basically, I need to be able to convert back and forth to referring to coordinates either in the standard degree system OR by measuring a distance north from the south pole along the international date line, and then a distance east starting from that point on the date line. To do this (as well as some more general distance-measuring stuff), I have one method for determining the distance between two lat/lon points, and another method that takes a lat/lon point, a heading and a distance, and returns the lat/lon point at the end

Is it possible to get the longitude and latitude value from IP address in asp.net? If it is possible, please let me know how can I get this. MaxMind Geolite city is free . If it is not good enough, you can apparently upgrade to a more accurate paid-version. I can't speak for the quality of the paid version, as I have never used it. If you like your SQL, download the CSV version . Load it into your database of choice, and query away. The faster and space-efficient option is to download the file binary blob version of the same database, and then use the C# class to query it. Alternatively, I

I would like to redirect my users to specific location areas in my website, by detecting their location from their IP address. What would be the best way to achieve this under Django 1.1.1 ? Thanks Edit: I want city based locationing on europe. GeoDjango looks like it will suit your needs. I'm not sure exactly how you would want to direct users, but using the GeoIP API , you can do something like: from django.contrib.gis.utils import GeoIP g = GeoIP() ip = request.META.get('REMOTE_ADDR', None) if ip: city = g.city(ip)['city'] else: city = 'Rome' # default city # proceed with city The Docs

How can I check if a geopoint is within the area of a given shapefile? I managed to load a shapefile in python, but can't get any further. Richard This is an adaptation of yosukesabai's answer. I wanted to ensure that the point I was searching for was in the same projection system as the shapefile, so I've added code for that. I couldn't understand why he was doing a contains test on ply = feat_in.GetGeometryRef() (in my testing things seemed to work just as well without it), so I removed that. I've also improved the commenting to better explain what's going on (as I understand it). #!/usr/bin

Right this is confusing me quite a bit, i'm not sure if any of you have noticed or used the "my location" feature on google maps using your desktop (or none GPS/none mobile device). If you have a browser with google gears (easiest to use is Google Chrome) then you will have a blue circle above the zoom function in Google Maps, when clicked (without being logged into my Google Account) using standard Wi Fi to my own personal router and a normal internet connection to my ISP, it somehow manages to pinpoint my exact location with a 100% accuracy (at this moment in time). How does it do it? they
