precision by specifying the use of those coordinates
within the grid system defined by the Military Grid
Reference System (MGRS). Additionally, it
addresses specific presentation issues such as
grid spacing. The UTM coordinate representation,
the MGRS grid, and the specific grid presentation
requirements together define the USNG.
A coordinate-based data structure commonly used
to represent map features. Each object is vector image
represented as a list of sequential x,y coordinates.
Attributes may be associated with the objects. A
computer image can be represented in vector
format or in raster format. See
raster image .
The Vertical scroll bar appears at the right of the
most windows. Use the vertical scroll bar to move vertical scroll bar
up and down. The scroll box inside the scroll bar
indicates your vertical location. You can use the

A Web Feature Service (WFS) client retrieves
geospatial GML (Geography Markup Language)2 Web Feature Services
data using HTTP GET and HTTP POST requests
over the Internet or through a private intranet. The
WFS client was developed in accordance with the
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.
