I’ve created a new html template for the GMapCreator that uses Google’s API v3. In addition to not requiring the API key which is locked to the URL, this also means that you can take advantage of Google’s new styled maps base layers and Fusion table overlays. The following map shows UK geology as the […]

As the Windows native version of the Java Advanced Imaging (JAI) project that the GMapCreator depends on is 32 bit only, I needed to use the pure Java version of JAI. It’s not immediately […]

The API uses simple commands to query for a list of stations, for example: http://api.wunderground.com/auto/wui/geo/GeoLookupXML/index.xml?query=london,united+kingdom Using C# and .net, this is accomplished as follows: WebRequest request = WebRequest.Create(string.Format(GeoLookupXML, @”london,united+kingdom”)); HttpWebResponse response = (HttpWebResponse)request.GetResponse(); XmlDocument […]
