Using the Radius Select Tool
The Radius Select tool 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 Select tool, you could create
a temporary list of blood donors that live within a one-half-mile radius of each blood donation site.
The Radius Select tool selects 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 you want to select objects from selectable. On the Map menu, click Layer Control
and click the Selectable icon for the layer. Make sure the layer is either at the top of the list, or
that the layers above they layer you want are not selectable.
2. Choose the Radius Select tool from the Main toolbar. 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 Professional
draws a circle around the point and reports the radius of the circle in the Status Bar (lower left corner
of the screen).
5. When you have the desired radius release the mouse button. MapInfo Professional highlights all
map objects that fall within that circle.
6. To see a list of all the records that fall within that circle, choose New Browser Window from the
Window menu. Choose Selection from the list of tables. MapInfo Professional creates a Browser
of the new selection table.
