The Radius Selection command selects all objects that fall within a given radius. For example, you have a table of blood donors and a table of blood donation sites. Using the Radius Selection command, you could create a temporary list of blood donors that live within a one-half-mile radius of each blood donation site.

Use Radius Selection to select all objects whose centroid falls within the circle. The object does not have to be completely bounded by the circle.

To select objects within a radius:

  1. Make the layer that you want to select objects from selectable. On the HOME tab, in the Windows group, click Tool Windows, and click Layers from the list, to open the Layers window. Click the Selectable icon beside the layer name to turn selection On.
  2. On the MAP tab, in the Selection group, click Radius Selection from the selection list. The cursor becomes a hand when moved over the Map window.
  3. Click a place on the map that you would like to use as the center point of your radius search. For example, if you want to select all the homes of all of the children that live within three blocks of the school, click the school icon and use that as the center point.
  4. Hold down the mouse button and drag the mouse away from the center point. MapInfo Pro draws a circle around the point and reports the radius of the circle in the Status Bar (lower left corner of the MapInfo Pro screen).


  5. When you have the desired radius, release the mouse button. MapInfo Pro highlights all map objects that fall within that circle.
  6. To see a list of all the records that fall within that circle, on the TABLE tab, in the Contents group, click Browser. Choose Selection from the list of tables. MapInfo Pro creates a Browser window with the new selection table.
