 In order to set this filter the user can:
 
 * Select the *Filter type* by choosing between **Viewport**, **Rectangle**, **Circle**, **Polygon** (selecting Rectangle, Circle or Polygon it is necessary to draw the filter's geometry on the map)
 
 * Select the *Geometric operation* by choosing between **Intersects**, **Is contained**, **Contains**

 Once this filter is set, it is always possible to edit the coordinates and the dimensions of the drawn filter's geometry by clicking on the **Details** button <img src="../img/button/edit-icon-1.jpg" class="ms-docbutton"/>. Editing a circle, for example, it is possible to change the center coordinates (*x*, *y*) and the radius dimension (*m*):

+     Also for [Dashboard](exploring-dashboards.md) [widgets](widgets.md) (charts, table and counter) it is possible to define a spatial filter without necessarily connect the widget to the map widget by using the usual **Area of interest** filtering section. The example below sows how:
