3) The topographic information is collected by digital photogrammetric data acquisition 
in analytical stereoplotters equipped with graphic terminals. Asia Air Surveys is in- 
stalling a digital photogrammetric data acquisition system at their premises in Tokyo. 
It consists of a VAX 11/730 computer linked with several Kern DSR 1 stereoplotters. 
a Kern GTI plotting table, graphic terminals and magnetic tape units. 
The topographic data, compiled from color aerial photographs taken with a normal angle 
(c » 30 cm), 23 x 23 cm format camera at the scale of 1:3300. In these the targetted 
control points, transfer points and utility manholes are visible. Their coordinates can 
be recorded and marked by an appropriate symbol in the data base. Topographic fea- 
tures, such as houses, road limitations, vegetation boundaries. water boundaries and 
contours are also acquired in digital form. In Kuwait a DSR 1 will be installed in 1985 
for updating and checking of topographic information from new aerial photographs.

H) The utility information is compiled at 8 further Intergraph interactive graphic work 
stations linked to another VAX 11/750 computer to be installed in Kuwait by March 
1985. The total computer configuration will then consist of 8 Mb main storage in the 
dual VAX 11/750 system and of disk storage facilities of 3000 Mb linked with 10 Inter- 
graph work stations, a Kongsberg GT 5000 flatbed plotter and a rapid multicolor plotter. 
  
For 
  
  
The utility input is made from the following sources: 
a] the coordinates of manholes, determined by a simultaneous photogrammetric bundle 
block adjustment in an analytical aerial triangulation. 
b) terrestrial simple distance measurements to toopgraphic objects such as house cor- 
ners, walls and street curbs. Such surveys are required, where electricity cables are 
to be detected by electric or magnetic cable locators. 
c) utility reservations based on cadastral boundaries (e.g. for a 30 m wide road: high 
tension cables 0,5 m away from the boundary: sewer 1,0 m away: low tension cables 
1.35 m away: drinking water pipes 1,8 m away, gas pipes 2.7 m away. irrigation 
pipes 3,2 m awa, telephone cables 4.65 m away. 
d) graphical representation in the utility plans 1:2000, if necessary extracted by a di- 
ance | gitizing table.

The system must be continuously updated on the basis of new survey records. Graphic 
map representations may be plotted at periodic intervals and distributed in microfilm 
form. 
The generation and the upkeep of such a global information system creates a number of 
detailed questions, which can only be solved jointly with the user administrations in an 
ey interministerial committee, which is now already operating. 
ence It is planned that each user ministry (Communications, Electricity and Water, Justice, 
Planning Dept. of Kuwait Municipality, Public Works] will eventually, after the 
establishment of the system in a 8 year period, have the possibility to update its own 
data base as far as geometry and especially the legal or descriptive attributes are con- 
cerned. This can be done by supplying each user service with additional work stations 
ooperated by a VAX 11/730 linked to the Kuwait Municipality Survey Department system. 
This will enable these administrations not only to utilize and to update the data, but 
also to develop their own dedicated task data management systerns. 
The KUDAMS-Project constitutes a model for the establishment of a global land infor- 
mation system in urban areas for the following reasons:

vork. 
al The system was conceived by the Survey Department, which has the expertise to 
n geometrically integrate all data 
b) the area of 580 km? is large enough to install the system: it is also small enough to 
handle the amount of data in an existing and serviceable hard- and software system, 
cells which only amounts to 15 % of the total project costs. 
c) it has been made possible that this geometric information system is equally suitable 
for input and the updating with different data acquisition methods, such as simple 
tape measurements, digital tacheometry, analog or analytical photogrammetry and 
the digitization of maps, always maintaining and coding the original survey accuracy.
