this option you can also choose to create the rings centered on the selected point feature(s) rather than
manually specifying a center location. You can cancel creation of the range ring(s) at any time by pressing the
Escape key or right clicking.
After selecting the center of your range ring(s), the Select Range Ring Parameters dialog (pictured below)
appears and allows you to setup how many range rings you would like to create and how far apart you would
like to create them. You can choose to create rectangles with the specified range as the radius rather than a
ring if you would like. You can also choose to create a "multi-ring". Checking this box will delay the actual
range ring creation until you have added additional range rings and unchecked the box. Then all rings in the
"multi-ring" will be combined if possible to build nice looking combined range rings.
Once you have completed have completed creating the range ring(s), the Digitizer Tool will remain in the
range ring creation mode, so you can simply left-click to create additional range rings centered on another
location, or right-click to choose a different mode.
The range ring feature has numerous applications, including search-and-rescue and aviation.
Creating Buffer Areas Around Selected Features
Global Mapper User's Manual
After selecting the Create Buffer Areas Around Selected Feature(s) option in the Advanced Feature Creation
popup menu, the Setup Buffer Areas dialog (pictured below) appears and allows you to setup how many buffer
areas that you want to create around each selected feature and at what distance to space them. For example, if
you want to create buffers at distances of 100, 200, and 300 meters around each selected feature, you would
specify that you want to create 3 buffer areas with a buffer distance of 100 meters. If you would like to
combine all overlapping buffers into larger combined areas, simply check the option to Combine Overlapping
Buffer Areas. To create buffers some distance inside a selected area feature rather than outside of it, simply
specify a negative buffer distance.
Once you have completed have completed creating the buffer areas(s), the newly created areas will
automatically be selected so you can easily right-click to edit them, display measurement information, etc.
