Materiale from the terrain interpretation are then send to 
the machine plotting group, which ie involved in planimetrie 
or planimetrie and contours plotting, depending on the needs 
/points 16 and 17 /• 
After finishing plotting of the individual sheet by the 
machine plotting groups, the material is forwarded to the 
field groups who carry out the supplementary surveying* If 
the photographs were not legible in the field, these groups 
complete the reconnaisance of property boundaries* After the 
completion of this work, these groups carry out the macro 
scopic review and check the accuracy of the map sheet, car 
rying the same responsibility for the final production of 
the map* 
The reviewed and corrected map sheet is then send to 
the cartographic section* 
3. ORGANIZATION AND ECONOMY OP LARGET SCALE MAPPING * 
In diagram 2 / resulting from technology / the intercon 
nected activity of the seperate groups is shown* 
In talking of economical and organizational aspects of 
plotting of large scale maps using the photogrammetrie me 
thod, we have to take under consideration the anlysis of 
large region* - The region of- southern Poland, as we said, 
is involved in a many year plan of mapping in a basic scale 
1*2000 / for urban areas 1*1000 or 1*500 /• 
In this study we are analysing one object having a area 
of 780 km and on its example we are showing certain accepted 
organizational forms of the production process f and the me 
thod as wise as possible use of equipment and technical per 
sonnel'! but only in reference to this object* However the 
whole problem is different if exist possibility of simulta 
neous organization of work on several of such objects and if 
we have opportunities in dead periods to move personnel from 
the field to the office* 
The full production cycle for an analysing object, ha 
ving an average degree of difficulty for photogrammetrie plo 
tting is shown on diagram 3* 
The production process shown on the diagram 3 encompas 
sing a cycle of 24 months and time synchronization of basic 
stages of production* It is not optimum cycle from the point 
of view of organizational efficiency and effectivness in the 
period of use of people and equipment* It is a conditioned 
cycle depending on * 
- flight period - in the area of southern Poland the best 
period for taking photographs is fall /September/, when the 
growing season has ended and atmospheric conditions allows 
taking the good quality aerial-photographs.
