Thanks for your reply.
Here is a URL that contains information on what I would like to be able to
render
on an OpenMap application.

Well the issue isn't to provide a UI to create these symbols. We already
have UIs in place with code we
wrote to supply this information to other mapping engines. The issue is can
OpenMap draw these images
on its map. Now I realize that OpenMap can do simple renderings of
information that is represented as a
point, ie units, ground tracks, air tracks and pretty much all of the point
geometries. Some examples of these images are,
G*FPPCB---****X a Fire Support Point
SUAPMF----***** A AIR TRACK MILITARY FIXED WING, Unknown
All of these images are able to be drawn because there is a jar that
contains the actual images for each
of these entities in a PNG format. The name of the files have the exact mil
std representation. For example, suapmf---------.png is the symbol of the
unknown Air Track Military Fixed Wing icon.
Which for me raises a couple question.
1) Can OpenMap support modifiers for these symbols.
The MilStd spec also defines modifiers that can be placed around the symbol.
Can OpenMap support this?
Especially for Air tracks, one of the modifiers is a directional vector
showing the current course of the track.
2) Can OpenMap support echelon information.
Pg. 54 of the given URL. Little symbols above the units icons showing the
size of the displayed icon.
Example, Squad, Section, Platoon. This information I believe is represented
in positions 11-12 of the
mil std string.
Now with that said, what OpenMap already provides is huge. Implementation of
the
Military Standards for graphical display is not an easy task. For many
reasons, one
being that I do not think they really thought it through. For example,
AXIS OF ADVANCE FOR FEINT mil std G*GPPA----****X. Is defined by three
points. (Pg, B93 of spec)
A begin point, a end point, and a width. But in reality this geometry can
have
hundreds of points defining its path. Which makes the spec almost impossible
to implement.
Well I am getting off into a tangent, My question is can OpenMap draw this
Axis of Advance or does
only know how to handle what is in the jar.
Sorry for getting wordy and thanks for your time.
