This is starting to become obsessive, but I can’t help wondering how many trains are running on the London Underground and where they all are. The Trackernet web service released by TfL allows you to see all the running boards for stations on a line, but doesn’t tell you where all the trains are. I did […]
Continue reading »In the previous three parts, I outlined the plan for getting geometry from MapTube via C Sharp into an FBX file using the C++ SDK provided by Autodesk. This final part shows data in a world map exported from MapTube and imported into 3DS Max. The above image shows the world countries 2010 outline from […]
Continue reading »The first two parts of the FBX export process dealt with getting the FBX SDK working and exporting some simple geometry. Now what’s required is the ability to pass complex geometry from the MapTube side using C# over to the FBX side using C++. The obvious way to do this is to pass the geometry […]
Continue reading »I’ve been looking at how to export the geographic information contained in a MapTube map into an art tool like 3DS Max or Maya. The reason for this is firstly to make it easier to produce high quality geographic presentations, but also, by employing a recognised art tool chain, we can also get the data […]
Continue reading »I’ve been meaning to look at TfL’s Trackernet API for a while now. It works through a REST based web service which gives access to all the London Underground running boards on a line by line basis. You issue an http request of the form: http://cloud.tfl.gov.uk/TrackerNet/PredictionSummary/V and the result is an XML file containing train information for […]

It was also a good opportunity to test out the new MapTube map creation software which can handle 35,000 clickable points on a map with ease […]
Continue reading »I’ve been looking at web-based sources of geographic data and Wikipedia links are something I’ve wanted to try out for a while. I found the following page containing Worldwide fossil sites: List of fossil sites This gives a list of sites, but with no locations: The “Site” column contains href links which can be followed to pages […]
Continue reading »We released a new feature on the MapTube website today which will make it easier to create new maps from data in CSV files. The underlying technology is used on the SurveyMapper site and for other real-time visualisations like http://bigdatatoolkit.org/2011/07/26/1yeartogo/ which shows tweets using the #1yeartogo hashtag for the London 2012 Olympics. The new update to […]
Continue reading »I’ve been looking at the Weather Underground API (http://wiki.wunderground.com/index.php/API_-_XML) which gives access to the observation stations and the data they are collecting. 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 […]
Continue reading »Recently, BBC Look East have been running a “Broadband Speed Survey”, asking people to use an online tester to check their broadband speed, and then enter the value, along with their postcode, into SurveyMapper. This generated 16,311 responses to the survey, but for each response people get to view the map containing the latest data, […]

Continue reading »We’ve just updated the MapTube website with a new release of the software that makes all of the Census maps clickable. Anything tagged with the “CENSUS2001″ keyword is clickable, as well as most of the maps made from the data on the London DataStore. The new clickable map icon. This is used to turn the clickable maps feature […]

Continue reading »With 649 of the 650 parliamentary seats from the 6th May 2010 General Election now declared, we can see how the policital map of the UK has changed. The one remaining seat is Thirsk and Malton where the death of one of the candidates means that the vote has been postponed until 25th May. This map has been […]
Continue reading »With the recent release of the OS Free Data and the up-coming election, I’ve been looking at Parliamentary Constituencies boundaries. It’s not clear from the accompanying documentation which boundary set the OS Free Data is based on, but the following image should clarify things. This is from the OS Free Data: Now compare that to the […]

The red thematic overlay is total population for every OA, which can be clicked to get the age group breakdown shown in the popup window. This map […]
