Population Area Centerpoint

Population Area Centerpoints

Description

A population area centerpoint is the center of mass of a populated area that includes States, Counties, Metropolitan areas, Cities, Towns. This information will be used in the programming of the new BCD996T and BCT15 scanners that include location based scanning capabilities.

The Site/System location setting on the scanners can be set for 0.5, 1, 3, 5, 10, 20, 30, 50 miles radius. This will create a circle of as small as 1 mile and as large as 100 miles in diameter. These circles should be placed over either the coverage area of a site or system or the center of population mass. Some areas will require multiple centerpoints for full coverage. This will require multiple sites or systems to be created on your scanner for coverage of that area. Since most areas have 4 greater sides the size of the circle (radius) should be large enough to cover the entire area (square - rectangle).

The Latitude Longitude information should be listed in whatever format works for you. There is a converter located here. Later when there is clarification there will be a required format.

The format should be added as the Arizona entry (in a hierarchical manner).
