the MGRS grid, and the specific grid presentation
requirements together define the USNG.

1.0.0 OpenGIS Web Feature Service
Implementation Specification, which is available
online:
A Web Map Service (WMS) is a technology that
gives you a source for data over your Intranet or
Web Map Services
over the Internet. This innovation is based on a
specification from the Open GIS Consortium (OGC)
and allows you to use raster map images from
servers that also comply with the specification. An
important element of this is that the WMS images
are registered using the data's coordinate system
so the WMS layer can be used with vector and
other registered raster images.
This specification supports transparent pixel
definition for image formats as well. This allows
you to use the images you retrieve as overlays and
not solely as the bottom layer of your map. This is
a very new technology and WMS may not exist for
the geography you are looking for. Further, the
WMS Server determines the data that is provided.
