Selection

The use of selection lists

Within a selection list you select one value with the left mouse button. However there are several ways to select more then one option:

• Select multiple consecutive values with [Shift] + [Left mouse button]
• Select multiple individual values with [Ctrl] + [Left mouse button]
• Navigate through the list by pressing on the first character

Criteria

On this page you can select pollutant or environmental theme, the year, and the environmental compartment. You can see the resulting map or graph by selecting the tab [2. Show], which shows the total emissions in the Netherlands. It is also possible to attune the selection to one or more specific sectors, activities or facilities using the tab [1. Select] - [1b. Sector/activity].

Emission sources

With an extensive tree structure you can select one or more economical Sectors, Sub-sectors, Activities and/or individual Facilities. It is possible to select a complete sublevel after selecting one level (which turns pink after selecting).

Presentation

Graph

The graph shows the development of emissions over the years. Every selected source, pollutant and sector is represented. The numbering of the lines showing the emissions is determined by the emission shown for the first year. See the table below the graph for the legend. You can order the table by selecting the heading of your preference. All emissions have a maximum of 4 significant digits. You can export the table to an Excel spreadsheet, which opens in the browser or in a separate window (depending on your settings).

NB: this is the best way to select your own sources or to see which economic sectors are important for your pollutant. However, you may want to select a mix of sources at different levels (sectors, sub-sectors, sources and facilities). Adding up these emissions in a spreadsheet could result in incorrect totals, so if you want to see all the sources it's better to use [3. Export] - [3a. Per Sector/activity].

Map

The map only shows emissions from the current selection given in [1. Select] - [1a. General] and [1. Select] - [1b. Sector/activity]. However, this selection can contain more than one year, source and pollutant and the map only shows one combination. For this reason you may want to make another sub-selection in de dropdown lists.

1. This section shows the choices made on tabs 1a en 1b. If you want to view a different year, a different compound or a different sector/activity then the ones supplied in the picklists you need to return to tab [1. Select] and repick. The picklist with in this example “gemeente” (municipality) shows the spatial representation layer. For each compartment (e.g. water, soil) other choices are availeble as representation layers. Compartments Air and Soil are represenented in grid cells 5x5 km, communal boundaries, provincial borders and some substances are displayed at 1x1 km grid cells. Emissions and load to water are displayed by: river basin districts, water board boundaries and catchment areas (gaf_90).
2. This input field is used to search the map. Initially it always searches through postal area codes. Depending on what is shown on the map other search options become available. E.g. when facilities are shown on the map than they become searchable; When municipality is used as a spatial representation, it is searchable. Search by starting to type, after two characters a result will be shown. It can be refined by continuing to type. After finding the item you want to see click it to select and zoom to it on the map. Also by hovering over an option in the picklist it will highlight on the map.
3. These three buttons are used to unselect , zoom the current map to full screen the current map by using[] and use to print or save a PDF of the current map results. Creating the PDF file requires up to 10-20 seconds.
4. These buttons are used to navigate the map. Zooming can be achieved by clicking the vertical bar or + and - buttons. Alternatively you can press [Shift] and drag the mouse over the map. Or use the mouse scroll wheel for zooming in and out. The arrows up and down, left and right can be used to pan the map. By clicking the globe you return to full map view.
5. With the options section the map can be further refined. Different background layers are available. Also alternative classifications can be made, or recalculation to emissions per km² can be shown. Please note, if you use the transparancy slider, the colours in the map change but the legend isn't updated accordingly. So the colours might diverge.

Classification of emissions in map

In general, emissions are not divided equally: many of the emissions are found in the lower range and a few extreme emissions in the upper range. If the standard classification of equal values is used, the lowest classes typically represent 90% of the values. This is why two alternative methods for classification are possible here: equal count and equal logarithmic value.

• Equal values: maximum value minus minimal value divided by the number of classes (8) (the standard option)
• Equal count: each class has the same number of values

Export

Per sectory/activity

The tab [3. Export] - [3a. Per sector/activity] gives an export of all sources for the selected pollutant(s), year(s) and compartment(s). All emissions have a maximum of 6 significant digits. The selected sources in the tab [1. Select] - [1b. Sector/activity] are not taken into account.

Per location

The tab [3. Export] - [3b. Per location] gives an export of the regionalized data for the selected pollutant(s), year(s) and compartment(s). All emissions have a maximum of 6 significant digits. The selected emission sources in the tab [1. Select] - [1b. Sector/activity] are not taken into account. You can limit the geographical area by de-selecting [Select All Areas] and selecting the individual areas or using the advanced filter.

Trouble shooting

Notation of numbers in Excel

Microsoft Excel has a default setting for decimal point or comma. This setting affects the import of CSV files. In the Dutch version a decimal comma (0,5) is normally used and in the English version a decimal point (0.5). You can change this in the settings of the Windows control panel by selecting 'Regional and language Options' or in Excel by selecting 'Tools - Options - International'. In Excel 2010/2013 you can find this option at File -> Options -> Advanced -> Use system seperators.

Settings

All emissions are presented in whole numbers, standard as kilograms per year. Here you can select another unit, e.g. grams per year for dioxin or kilotonne for CO₂. The selected unit is used in the graph, map and spreadsheet. However, in the tab [3. Export] the data is always presented with 6 significant digits, in kg and with a decimal point (in the Netherlands a decimal comma is standard). See Numbers in Excel, decimal point or comma.

Search

Search documents

After selecting [Search in documents] in the menu to the left, you can search any string inside the document itself. Documents may be written in Microsoft Word, Adobe PDF, Microsoft Powerpoint, Microsoft Excel or HTML pages. Your search-string should contain at least 2 characters and may contain a combination of the following keywords.

• Emission
• "Emi*"
• Emission AND 2010
• Emission NEAR 2010
• "Emi*" AND IPCC

Search facilities

When the field facility is selected you can search for a facility on a map by typing at least 2 characters of the name of the facility next to the button and pressing [Search]. One or more names are shown below. Selecting one name moves and centers the map to the given location.

Search postal/zip-code

In the homepage and in the page with the map itself (Show - Map) you can give in the four digits (xxxx) of your postal code. The map will zoom to that area.

Search in a map

You can search for names in a selected layer of the map (province, municipality, river basin district, catchment area or water board). Just type in at least two letters and press the search button.
