2.1 – Get feature info

The Get feature info tool is used to return attribute information for the queried layer*. To use this tool, activate Get feature info by clicking the tool so it becomes dark grey. The mouse pointer will appear with a question mark attached so you know that Get feature info is active. Click on an area of the map where you wish to find about more information about the features. A pop up will appear over the area selected displaying attribute information. To close the pop up, click the X.

You can deactivate the Get feature info tool by clicking on the tool again so it turns light grey.

*NOTE –  The Get feature info tool is enabled for all layers however, there may be some datasets that do not have valid attributes therefore will return none when selected.

2.2 – Zoom to home bookmark

To use this tool, you must set up a bookmark that you would like to use as your home bookmark. To do this, please refer to section 2.4.

This tool is used if you need to set a specific location in the map view that you frequently go back to. Once you have set your home bookmark, clicking the house icon will return the map view to the view extent set as your home bookmark.

To set your home bookmark:

  • Click Account
  • Click My Preferences
  • Choose the bookmark you wish to use as your home bookmark from the dropdown list
  • Click save
  • A popup confirming that you preferences have been changed will appear

2.3 – Toggle overview map

The overview map is a small map in the top right of the map view to give you context of where the map view is at a larger scale. Simply click the tool to turn it on or off. You can also move the red dotted rectangle within the overview map to move the main map view.

2.4 – Toggle bookmarks panel

Clicking on this tool will open up the bookmarks panel. A bookmark is used to save a particular view extent in the map view. There are some default bookmarks already saved for your use.

To create a bookmark:

  • Click the Toggle bookmarks panel icon
  • Click the + for add new bookmark

To delete a bookmark, click the bin symbol next to the bookmark you wish to delete.

2.5 – Zoom buttons

The magnifying glass symbol with the plus zooms in to the map by one level with one click. The minus sign magnifying glass symbol zooms out of the map one level with one click.

2.6 – The Layer Manager

The layer manager is a tool to help you view all the layers you have open in the map viewer and to control how the layers can be seen. For example, you can use the layer manager to reorder the layers to change which layer is shown on top or bottom of the map. It can also be used to change the opacity of a layer, the visibility and shows the coverage for some layers. This user guide will help you to make the most of the layer manager to create the maps you need.

2.6.1– Accessing the Layer Manager

The Layer Manager is available from the Map View. To access the Map View click Map at the top of the geospatial data service. You should then add in the layers you wish by using the slider. For more information on accessing the Map View and adding layers to the map, please refer to the Catalogue Menu User Guide.

Once you have added in the layers you require to the Map View, you can open the layer manager. To do this click the second from bottom button on the Map View Toolbar. This will open up the layer manager on the right hand side of the Map View, where you can see all the layers that have been loaded in the map. If a layer is shown in a grey colour, this means that the layer is not visible at that zoom level and a message will be shown to make you aware.

2.6.2 – Layer Manager Tools

The tools within the Layer Manager are described in the picture and table below.

1 Exit the Layer Manager This button closes the Layer Manager.
2 Add Layer This button is used to add WMS or WMTS layers to the map view. For more information, please see section 3.1.
3 Reorder layers To reorder which layer appears on top of the map, click and drag the layer name up or down the layer stack. The order shown in the layer manager will correspond to where the layers appear in the map. Further information on this tool can be found in section 3.1.
4 Opacity slider Drag the point along the scale to adjust the layer opacity. The layer is automatically set to 100% opacity.
5 Go to visible zoom level This button zooms the map viewer to the zoom level that the selected layer becomes visible. If you load in a layer and cannot see the data, use this button to take you to the correct viewing zoom level.
6 Delete layer This button removes the layer from the map view and unselects the layer from the catalogue.
7 Add layer to comparison map This button adds the selected layer to a comparison map. More detail on the comparison map can be found in section 3.2.
8 Coverage mode This button shows you the data coverage for each dataset. Additional metadata information may be available for some layers within the coverage layer and this can be found using the info tool or the map will be symbolised according to the information e.g. Aerial Photography’s coverage is coloured by the years flown.
9 Disable layer This button switches off visibility of the layer. The layer will not be deleted and will remain in the layer manager. If the layer is disabled, the icon will be greyed out. To switch visibility back on, simply click the icon again to bring it back into view.

2.6.2.1 – Add WMS, WMTS and shapefile layers

The Add Layer button at the top of the Layer Manager is used for adding in WMS and WMTS layers to the map. To do this, click the Add Layer button and a pop up box will appear.

Enter a name for your layer in the field at the top of the pop up. Then select the service type you require, either WMS or WMTS and whether authentication is required. Finally, enter the URL of the layer you wish to add and click Add. Your layer will now be visible in the map viewer.

2.6.2.2 – Reorder layers

You may wish to change the order of which layers appear at the top or bottom on the map viewer. This is simple to do using the Layer Manager. Just click and drag the layer you wish to move in the layer manager and place it in the correct location.

For example, in the layer manager below two layers have been added to the map. Currently, the Historic Map layer is listed above the OS Open Roads layer. The OS Open Roads layer is not visible in the map viewer because the raster layer is on top of the vector layer. If you want to view the OS Open Roads on top of the Historic Map layer, click and drag the layer names to reorder the stack so that OS Open Roads is at the top of the list. Now both layers are visible in the map view.

  

2.6.2.3 – Comparison map

The comparison map is a useful tool to view two maps side by side. To choose a comparison layer, simply click the two arrows icon as shown in section 3. This will show the selected layer in a separate map to the right hand side of the main map. The two maps will now be aligned to the same spatial area, so moving or zooming one map will move the other at the same time.

To exit from the comparison map tool, you can either click the X on the comparison map title or click exit within the layer manager.
