                     UK AURN Stations in Google Earth™ – User Guide


    This document describes how to use Google Earth™ to display information about the UK
    Automatic Urban and Rural air quality monitoring network. In order to have full functionality,
    please ensure that you have the latest version of Google Earth™ installed on your computer.
    You can click here to check for updates.

    1 - Open AURN stations file in Google Earth™
    The file “AURN Stations.kmz” can be downloaded from the AURN website. When clicking on the
    download button, if you have previously installed Google Earth™, the file should open directly in
    the interface. If not, download the file in a local directory then double-click on it to open it in
    Google Earth™. You can also open Google Earth™ first then go to File menu, and choose
    “Open” to load the file.

             Depending on configuration and version of some internet browsers, the file will sometimes be recognised as
             a zipped file (.zip compressed file format). If this happens, then save the file in a local folder, unzip it (using
             WinZip software) and double-click on the extracted file (.kml) to open it in Google Earth™. Note: This feature
             will be removed when we will transfer the website on our new server.




    By default, the file will be loaded in your “Temporary Places” folder, which can be accessed in
    the “Places” panel on the left side of the interface. You can then drag and drop the file in your
    “My Places” folder. This way, the file will be automatically loaded next time you open Google
    Earth™. Otherwise, next time you want to open the file, just double-click on the file
    AURN Stations.kmz, which will launch Google Earth™.

    The file is actually linked to other files on our server, which contain all the information to be
    displayed (Network Link). These files will be updated on a regular basis. Therefore, you will
    always load the latest available data, in case new AURN stations are installed or previous ones
    are closed.

    The first time you open the file, Google Earth™ will connect to the server to download the
    information, which may take up to a minute or more, depending on your internet connection.
    However it will be much quicker next time you open Google Earth™. If you experience
    connection issues with the server, you may need to refresh the folders on the “Places” panel, as
    shown in the figure below:
         o   Select relevant folder (for example, “Current AURN Monitoring Stations”)
         o   Right-click and select “Refresh”

    Google Earth will then try to reconnect to the server to download the relevant data.




    2 – Display AURN Stations and additional data
    By default, when opening the file, Google Earth™ will zoom out and show the whole UK map in
    the main window and display the AURN stations, as follows:

AURN Monitoring Station – Google Earth User Guide




    You can navigate in Google Earth™ and zoom in to check the exact location of the monitoring
    stations. You can either double-click on a station to fly to the area (at street level), or zoom in
    progressively by double-clicking next to a station or using the mouse wheel. If Google Earth™ is
    too slow to zoom in/zoom out, the speed can be changed in “Tools” “Options” in Tables
    “Touring” (Fly-to speed) and “Navigation” (Mouse wheel settings).

    Note that the maximum resolution of satellite images can vary depending on the area, so you
    may not be able to see the detailed location, especially for monitoring stations in rural areas.
    Google first started to provide high-resolution images for large cities and urban areas, but they
    keep on updating the coverage over the UK on a regular basis, and higher resolution images
    should be available later on.

    It is also possible to display additional information in the main window, using the Google Earth™
    built-in layers in the “Layers” panel on the left side. For example, it can be useful to select
    features such as road network, nearby places or terrain to view the close environment of a
    monitoring station.

    3 – Display monitoring station detailed information
    When clicking on a monitoring station, a pop-up window will appear in the main window (see
    figure below). The window contains detailed information about the station, such as the address
    and type of the station, pollutants measured, start and end of monitoring, etc…

    The information window also contains web links, which you can click to open a website for
    further information. Normally, the web link will open a web browser within Google Earth™. If this
    is not the case, you can set up Google Earth™ to display web pages within the main interface:

    o    Go to “Tools”  “Options”
    o    In the “General” Tab, under the “Display” section, unselect “Show web results in external
         browser”
    This way, you will be able to navigate on the website from the interface, as shown in figure
    below. The web browser window can be displayed either at the bottom or on the right side of the
    screen using the buttons right of the URL box.

                                                                                                               the web browser
                                                                                                                   window

    The links available in the detailed information window are:

    o    Details on AURN website: this will open the AURN website to give you access to other
         extra information such as details of the location and photos of the site
    o    Site Type: This will display more information on the classification of monitoring sites
    o    Pollutants: This link gives access to all monitoring data of a specific station available on the
         National Air Quality Archive website. You can then open Excel files of measured
         concentrations for each pollutant and each year within Google Earth™.
    o    Street map view: this will allow you to view the detailed map of the surroundings of a
         station at street level (based on Google Maps™). This can be useful to identify roads
         nearby, as Google Earth™ does not automatically display all road names (see Figure
         below).

    4 – Filter and select monitoring stations
    By default, Google Earth™ will display all the current monitoring stations over the UK, classified
    by pollutants. However, the drop down list of folders in the “Places” panel allows you to display
    a number of information:

    o    Current AURN monitoring stations: this folder contains all active monitoring stations over
         the UK
    o    Closed AURN monitoring stations: this folder contains the monitoring stations that are no
         longer in activity. However, all the air quality data are still available and can be downloaded
    o    Automatic Hydrocarbon Network: this folder contains only the monitoring stations which
         are part of the national automatic hydrocarbon network. Both open and closed stations are
         listed
    o    UK Zones: you can use this layer to display the borders of the UK geographical areas
    o    Legend: Select this folder to display the AURN monitoring station legend

    For both open and closed AURN monitoring stations, you can choose to display only a category
    of stations, by site type, geographical area or by pollutant. This can be useful if you only want to
    see, for example, kerbside sites, stations in London area, or stations monitoring SO2 only.

    The following figure shows the contents of the “Places” panel with a description of available
    options.

    To display a specific subset of monitoring stations:

    o    If all monitoring sites are displayed, first unselect the box on the left of the file “UK Automatic
         Monitoring Networks.kml”
    o    Then if you cannot see the full drop down list of folders, click on the “+” button next to the
         folder name you want to explore. This will expand the folder and show its contents.
    o    You should see 3 subfolders called “Site Type”, “Geographical Area” and Pollutant”. First
         click on the “+” button next to one of these folders

    o    Now you should see a list of subfolders, which contain stations from the specified category
         only. For example, if you chose to expand the folder “Site Type”, you will see subfolder
         named “Kerbside”, “Roadside”, “Rural” and so on. If you expand one of these folders again,
         you will see the stations sorted by name in this category. The figure in brackets is the
         number of stations within this category
    o    If you tick the box next to a specific folder, Google Earth™ will display only the stations of
         that type in the main window. If you have zoomed in to street level and you want to see at
         once the location of all stations within a specific category, you can also double click on the
         relevant folder (“suburban” in the example below) and Google Earth™ will zoom out until
         displaying the entire zone covered by the stations, as shown below
