The order of the layers of the printed map is set by the order in
which the layers were turned on. The last layer selected will
appear on top. The drawing order on the mapping portal is pre-set,
therefore the printed image may differ from what is seen in the
current map view. All layers will have no transparency in the
printed map view.

: Clicking this
button opens a pop-up window. There are different categories of
filters that can be applied such as Protected species in Special
Areas of Conservation. Multiple features within each category can
be selected by holding down the ctrl button on the keyboard while
clicking options from the list. Clicking the “Filter” button to the

for at least one of the chosen features will be highlighted.
The pop-up can be closed using the “x” in the top-right hand corner
of the pop-up and the filter layer will still be visible on the
More than one filter category can be applied at once. They all
highlight MPAs in a different way, so it is possible to see which
MPAs are included in which filter.
The legend for the filters will be visible on the Key tab of the
main map page.
All filters will remain on the map until the “Remove Filter From
Map” button at the bottom right of the Layer Filter pop-up is
clicked. Clicking this button will remove all filters that have
Search for MPA
: There is a
search box above the mapping window to the right. Type the name, or
part of the name, of a Marine Protected Area (MPA) you are
interested in and a list of search results will appear below. Click
the name of the MPA you want and the map will zoom to the site
(depending on the dimensions of your screen, you may need to scroll
the page towards the right to see the full names of the search
results). If the relevant MPA boundary layer was not already turned
on, it will come on automatically.
Three tabs offer you different functions without having to
re-draw the main map page.
The welcome tab is shown on entering the webpage, which gives
an introduction to the Interactive Map.
All map layers are listed on this tab with the layers grouped
into folders and subfolders. Clicking on a folder or subfolder will
display the expandable list of layers within it; clicking the
folder again will collapse the layers. Make a layer visible by
clicking the check box next to its name. The legend for that layer
will appear once it is selected.

Adding layer(s) from other mapping
Using the UK MPA Interactive Map it is also possible to view
layers from other Interactive Maps, such as MESH Habitat data. This
is achieved by clicking on the Add more Layers
button at the bottom of the Layers tab.
Portals can be chosen from the drop-down list, or if a Web Map
Service (WMS) address is known, using the Custom...
option. If the WMS server has arranged layers in groups, the
Use layer groupings tick-box may be ticked to view the
layer in a simpler format.
Layers will appear in a new folder below the permanent layers
folders. Sliding bars beside the layer name allow the
transparencies to be changed.
