Grid Overlay widget

The Grid Overlay widget allows you to quickly render a U.S. Military Grid Reference System (MGRS) grid using client-side resources in a web application. MGRS is an alpha-numeric system, based upon the Universal Transverse Mercator (UTM) and Universal Polar Stereographic map projections, for identifying positions. An MGRS coordinate consists of a zone designation, alphabetic 100,000-meter grid square designator, and numeric coordinates within the 100,000-meter grid square. The widget allows an application to display MRGS grid dynamically at different index levels inside the application based on the scale of the map display.
