6.2. Thematic mapping

This section describes the four vector layers which the user has at his disposal for thematic mapping: "Thematic layer 1", "Thematic layer 2", "Facility layer" and "Symbol layer".

6.2.1. Thematic layer 1 and 2

The two thematic layer panels let you use your data for thematic mapping. All you need to do is selecting your desired indicator/dataelement-period-map combination, then the organisation unit level and finally the parent to define the boundary. If your database has coordinates for these organisation units they will appear on the map.

You may choose between legend types: automatic and predefined. Automatic means that the application will create a legend set for you based on your what method, number of classes, low color and high color you select. Method alludes to the size of the legend classes. Set to Equal intervals they will be “highest map value – lowest map value / number of classes”. Set to Equal group count the legend creator will try to distribute the organisation units evenly. Choose Fixed bounds and you may define your own class break values, type e.g. “20,40,60” using a comma to separate each of them. The legend will appear as an even gradation from the start color to the end color. Predefined legend sets are described in Section 6.3.2, “Register legend sets” .

Low radius and high radius only have effect on points (facilities) and decides the the circle radius for points with the lowest and highest value.

The map view combo box lists all map views (favorites) saved by the user. The settings that are stored in the map view is automatically applied to the thematic map panel. Favorite map views are described inSection 6.3.1, “Register favorite map views” .

All available layer options are now grouped together in the thematic layer menu, see picture below.

Edit layer: Opens up the layer configuration window, see the thematic mapping screenshot.

Refresh: Refreshes the map boundaries, data and legend. Usually not necessary.

Clear: Clears the entire layer, i.e. the configuration window, the map and the legend panel.

Filter: Opens up the filter window and lets you filter out organisation units from the map by value. See the picture below.

Search: Opens up the search window and lets you search for and locate organisation units on the map. See picture below.

Labels: Opens up the label window and lets you add labels to the organisation units on the map. See picture below.

Opacity: Set the layer opacity/transparency to 10, 20, 30, 40, 50, 60, 70, 80, 90 or 100%. Higher values of opacity make the layer more transparent, so that the underlying layer is more visible. An opacity level of zero will provide a fully opaque layer.

History: Provides you with a list of your 10 previous maps/selections. They are temporary and thus gone when the application is restarted.

6.2.2. Facility layer

This layer displays icons that represent facilities based on the facility type. Currently, "Type" is the only supported group set. Polygons will not show up on the map, so make sure to select a facility level. Click an icon on the map to open the context menu with two options. "Show information sheet" provides you with data for several data elements for this organisation unit. The data element group and period type are "system settings" called "Infrastructural data elements" and "Infrastructural period type". The second option in the context menu is "Relocate" and lets you graphically move the organisation unit to a different location. The new coordinate will be stored permanently.

6.2.3. Symbol layer

This layer displays icons that represent areas/polygons like provinces, districts etc instead of facilities/points. Thus, in this layer you are not supposed to select a facility level, but instead a level of provinces, districts etc. In order to render this layer you need to create a predefined legend set of images, described in Section 6.3.2, “Register legend sets”.
