4. Elements of comparison among the 
coordinate of the places 
A comparison among the coordinate estimated 
with the adjustment of the two networks and 
from that one obtained from the cartography at 
small scale, can be done with statistical 
methods and with the examination of all the 
coordinate even if the sample doesn’t allow to 
make a reliable observation. 
The principal statistics gave, for each 
component, the mean and the variance. 
The sample is not big enough to allow to use 
robust statistic such as the median or the 
median absolute value (mav). They have 
respectively the following values: 
Mean 
Variance 
• Meridian component: -14 
249 
• Transversal component: 156 
208 
The following tables report the coordinate of 
the places, estimated with the adjustment of the 
two network and of the cartography at small 
scale.
