that has been gathered. Geometric relations can be
applied at this stage or as a part of the computation
for the connection to the existing maps.
6. CONCLUDING REMARKS
This paper contains only a brief sketch of the contents
of the parts on photogrammetry and quality assurance
of the new manual for the technical activities of the
cadastral agency of The Netherlands. The standards
and guidelines for new aspects of photogrammetric
mapping in The Netherlands have been emphasized,
e.g. the use of digital photogrammetry and mono-
plotting for map revision.
Applying mono-plotting one should be aware of the
effects of height differences on the position of the
features in the map, even in a flat-looking country like
The Netherlands.
The possibilities of a smaller photo scale (currently a
factor 3 between map and photo scale is adopted)
needs further investigation. With the current contents
and precision requirements for the large-scale base
map, image interpretation is the limiting factor for the
photo scale.
