For the verification of the orthophotoplan precision the sets of
image coordinate are compared with the correspondent ones in
the field. We close with a synthetic table referring to the
precision requested in the DTM and orthophotoplan realization,
according to the flight scale and the orthophoto scale:

4. CONCLUSIONS
During the transition/post-transition period, the National Project
and the applications in the field of digital photogrammetry (in
both hypostases - hybrid and complete) proved to be adequate
to the national interest and to the requests of the European
integration: economical development, social stability and
environment management. In truth, according to Romania’s
long-term strategy, the orthophotoplan represents the
informational fundament for the realization of the index
cadastral plan, but also for the realization of thematic GISs, for
the LPIS (Land Parcel Information Systems), which is
stringently current for the subsidizing of Romanian agriculture
by the European Union.
