Especially for features where each observation is made at a different location the Map View layer type Observation Property as Value – Midpoint is a very good way of displaying not only where an observation was made but at the same time also show the value of a selected property of the observation as text together with an optional color coding and sizing according to the value.

While this layer will always show the observations as a simple point (using the midpoint of the actual geometry of the observation) that midpoint can be sized according to the observation value and can also be colored according to the value.

Configuring the layer

Configuring the layer is quite straight forwards.

If you get the expected result continue to the next section, else modify configurations or add or remove features.

Save the map view template

Saving a map view template will allow you to reuse the template as defined and reuse later. This will save a lot of time for you and enable using this template further say in report.

Saving a map view template steps

The steps to save a map view as template are:

  1. Click on the “Gear” for more settings.
  2. Enter a speaking name for the template and “Grouping path” text when you want the stored templates to appear in a folder in Data domain context tree.
  3. Drag and drop a Data domain in which the template will be stored. Please keep in mind the data propagation. For more information on this please refer to Presentation templates.
  4. Click the save button
