I have included all of the point data, the EMS
dispatching centers, fire stations, medical centers, and police facilities are
all items that should be on an emergency management reference map. I included schools because they are often
used as staging areas, relief centers, and temporary shelters in
emergencies. The location of jails may
be relevant if outside law enforcement agencies are called in for assistance. Looking at the data attributes, some of the
facilities appear to be administrative sites, which might not be needed on the
map, however, the location of these facilities might need to be shown since
they may have an administrative use or parts may be occupied by outside
agencies during an emergency. The line
data included a street, stream, and railroad file. I used all of these, but used queries so that
only interstates, major roads, and active railways would display to reduce
clutter. I used the airport, county, and
flood plain polygons, but did not use the forestry polygon.
The point data was symbolized using standard mimetic symbols
in ArcView. The stream, railroads,
interstates, and major roads are also symbolized using ArcView standards. The polygons are outlines with no fill except
the floodplain where I used a light grey so that it could be recognized without
adding unnecessary clutter to the map.
At this point I have labeled all of the point line and
polygon features that needed labels using ArcView’s auto-labeling
capabilities. Significant editing of the
label locations and styles is still required.
Although not called for at this stage of the lesson, I did
include a basic legend, north arrow, scale bar, and date (my pet peeve, all
maps should be dated). I expect to
improve them in the next lesson.
