This document provides an overview of The Simple Map Viewer and highlights a few of the primary tool areas users will most likely want to interact.

After clicking “View the map” and acknowledging the limitations of use as listed in the Disclaimer Window, the European map with the latest daily gamma-dose-rates (GDR) data will appear.

The Map viewer can be accessed from any computer with an internet connection and does not require a licence or subscription. It utilises a "responsive" design, meaning that its functionality and appearance is optimised to suit the type of device that it is being viewed on e.g. a desktop computer vs. a smart phone.

By default the map will show the latest Gamma Dose Rate aggregated averages from the approximately 5000 European gamma-dose stations as hexagons and discriminate these values as by colours.

  1. Map toolbar on the left-most side of the window allows the selection between average Gamma Dose Rate and maxima Gamma Dose Rate, both computed for last 24 hours. The threshold levels for each of these colours are indicated on the “Legend” area.
  2. Clicking or tapping on the area of interest will open stations bar at the left side of the window. This bar will contain the list of monitoring stations covered by the selected area. Clicking or tapping on the station will open the station time series charts.
  3. Buttons at the most right bottom corner are used to zoom in and zoom out. You may like to use mouse scroll for the same functionality.
    Quick geolocation button is very useful when you need to point at your present location, especially on mobile devices. NB: this functionality must be enabled in the settings of your computer or mobile device.
    If you have a computer with a touchscreen or use mobile device to display the map, you can use gestures (motions that you make with one or two fingers) for zooming and panning.
  4. [Deprecated] Search at the top of the map may be used for finding a place by name e.g. name of the country, city, town, village, region etc. After clicking the button “Go” map will zoom at the chosen place.
  5. When the station on the left side bar is selected a small popup window appears along with the time series. This popup contains 3 buttons. The button at the middle will reopen station's time series when it necessar, while the right button opens details map for this station.
    Note, you can to follow the selected station while changing the map extent. The popup doesn't get removed during zoon-in zoom-out or pan operations, unless the left button on the popup is pressed.

Each station displayed in the stations bar (2) acomplished with data time series. The most recent daily and hourly Gamma Dose Rate averages displayed in the form of line charts. Name of the station and country flag to which network this station belongs shown at the title.

  1. Daily Gamma Dose Rate averages, this chart shows how many gamma rays the monitor detects each day for the period of last 30 days
  2. Hourly Gamma Dose Rate averages, this chart shows how many gamma rays the monitor detects each hour for the period of last 24 hours.

Please note that hourly data may be absent due to various reasons such as instrument maintenance/repairs, telecommunication disruption, and server unavailability on the site of data provider or other technical issues. EURDEP does not take any responsibility for such data absence.

Stations details map

More detailed stations map appears when the side bar "Show more details" button or the left tooltip button clicked. This section contains 2 main parts.

  1. List of Gamma monitoring stations active over the last 24 hours. Each station has indicator for displaying Max, Min, and Average dose rate for the period of last 24 hours. Buttons on the right side may be used to indicate the map location and to show the time series of this station.
  2. The map shows all monitoring stations, including these which did not submit the data during last 24 hours. Blue circles show clustered station markers with the number of stations in the cluster. Clicking on the cluster will show all stations in that cluster. Use zoom-in functionality to de-cluster stations in smaller map area.
Information feeds

Registered users can create custom maps and subscribe to information feeds e.g. to track abnormal measurements reported by monitoring stations in the user's selected area e.g. home town, country region etc.

Log In required to use this functionality. How to register and log in is explained HERE.

  1. Optionally, search may be used for finding a place by name e.g. name of the country, city, town, village, region etc. After clicking a suggested option the map will zoom at the chosen place.
  2. Use map controls i.e. Rectangle or Polygon selectors to specify exact place where your favourite stations are. You can toggle between different selector types using buttons at the left top corner of the map.
  3. Specify a title (give a name to your selection, can be anything e.g. My town) and then click SAVE button. Your selected stations will be stored as RSS feed in My Feeds area. Use of this area is straightforward, thus is not described in this tutorial.
