Enhanced geometric accuracy will result 
from: 
(i) special affine transform actions; 
(ii) improved accuracy in relationship 
between the stereoplotter's floating 
mark and raw image through use 
of eight fiducial marks with 
unambiguous central marks 
Viewing comfort of the Operator may be 
increased by the special application 
of anamorphic corrections in the image 
scanline direction to compensate for the 
viewing angle effect and for Earth's 
curvature. 
CONCLUSIONS AND RECOMMENDATIONS 
(a) Developing countries subsist 
virtually. entirely on agriculture, 
In addition, they are experiencing 
the highest population explosion. 
Border mapping, therefore, has 
assumed an intrinsic value for 
Developing Countries. 
(b) In view of its prevailing circum- 
stances, border mapping demands 
fast production and presentation 
of the mapping data in a format 
that allows unimpeded retrieval of 
any required scale, as well as easy 
up-dating and storage. 
(c) Satellite mapping is best suited to 
meet the requirements of border 
mapping in terms of timeliness, 
format of presentation and up-dating 
possibilities. 
(d) The proposals itemised in section 6 
of this presentation are recommended. 
They will lead to a higher quality 
of border mapping. 
(e) Developing Countries should see 
satellite mapping technique as a 
means of achieving border mapping.
