5 The Preparatory Work of Intelligent Plotting System

5.1 Military Symbol Data Preparation

From the analysis and the demand of plotting, we need to determine the military sym-
bol, we can use a unique identification code to identify the military symbol, using this
code we can prevent the military symbol from ambiguity problems.
If we use the digital coding mode to mark military symbol, such as the identifica-
tion code of military symbol for a command post is 20001, then plotting personnel
should remember 20001, the problem is the number is not easy to memorize, we
should adopt a method which plotting personnel is familiar with.
According to the “The military symbol Regulations”, each military symbol has a
name, and the name used in the military is common, so we should use the name of the
military symbol, it accords with military personnel's habit. Therefore, it is reasonable
to use military symbol's name in the plotting command. Combined with the need of
computer recognition and people read, we can design the military symbol—name
table in order to realize the intelligent selection of military symbol, the structure of the
table is shown in the following table.

Table 4. The structure of military symbol - name corresponding table

Name Type

Military symbol name string

Military symbol library ID int

Military symbol code int

After the establishment of the corresponding table, we can use the plotting module to
plot, because we can use the military symbol name to query the military symbol code.

5.2 Geographic Spatial Data Table

In the speech plotting command, there are three ways to determine the military sym-
bol position, including latitude and longitude, Gauss coordinates and place names. By
using the latitude and longitude coordinates and Gauss coordinates, GIS can navigate
directly to the location, by using the place names, you need to find the place's corres-
ponding position coordinate.
In order to determine the corresponding position of the place, we should construct
a corresponding table, this table is used to record the corresponding coordinate of
places. The structure of the table is shown as follows.

Name Type

placename string
