factory, waterhouse, hospital, clinic, welfare institution, 
asylum for incurables, almshouse, police station, prison, 
stable, poultry farm, etc.) and are considered to the 
correspond to one title each. 
The total number of titles (for buildings in 1990) is 
5,628,000, so for 1996 there could be 6,000,000 titles, 
which according to the N.S.S. belong to 3,500,000 
landparcels. Knowing that the total number of landparcels 
in the jurisdiction is estimated to be 15,000,000, it can be 
concluded that the remaining 11,500,000 landparcels 
correspond to an equal number of titles for rural or urban 
parcels which have no building on them. 
The total 6,000,000 titles referring to building titles have 
been classified into three classes. Building of small 
landparcel value are estimated to be the 309^ of the total, 
where buildings of medium landparcel value account to the 
50% and of large landparcel value to the 20% of the total. 
By considering an average recovery charge for each 
class, it is given: 
6,000,000x 30% x 30,000 drch = 54 billion drch ($220 M) 
6,000,000x 50% x 70,000 drch =210 billion drch ($857 M) 
6,000,000x20% x 200,000 drch=240 billion drch ($980 M) 
For the remaining 11,500,000 landparcels without 
buildings, it is estimated that the 10% of them is barren 
land, the 30% is of small mean landparcel area, the 50% is 
the mean landparcel ownership in Greece and the 10% is 
large ownerships. This classification gives: 
11,500,000x1096x10,000 drch = 11.5 billion drch ($ 47 M) 
11,500,000x30%x20,000 drch = 69.0 billion drch ($282 M) 
11,500,000x50%x30,000 drch =172.5 billion drch ($704 M) 
11,500,000x1096 x80,000 drch - 92.0 billion drch ($375 M) 
In total, it is estimated that the recovery charge will be 845 
billion drch ($ 3.45 million). Yet, the cost for the collection 
fees for this charge should be substracted. These fees will 
be the 596 of the total, so the final recovery charge will be 
approximately 800 billion drch or $ 3.3 billion. 
3.2 Transaction Duties 
The income of the Cadastral Bureax can be derived from 
the following sources: 
e the right to sell to the owners, cadastral information 
concerning their ownership. This information can be 
either documentation certificates such as title copies, 
mortgages etc, or cadastral diagrams and maps of the 
ownership 
e the right to sell digital data, geometric information (i.e. 
network information, utilities, roads etc, useful to the 
local authorities and other agences) and thematic 
information (i.e. land uses, land values etc) which will 
be collected during the compilation phase. The 
Cadastre could also sell cartographic information of 
high accuracy for the whole country, such as DTM, 
orthophotos, orthophotomaps or other products useful 
for regional planning etc. 
The income derived from the transaction duties are 
comparatively equivalent to the income of the Mortgage 
Bureax for similar services. According to very recent 
statistical data, the mean annual average of this profit for 
the period 1991-1993 was approximately 8 billion drch or $ 
32.5 million, with an increasing tendency, for the whole 
country. Taking into account that the Cadastral Bureax will 
provide much more information, i.e. cadastral maps, it is 
rational to be expected that the income of the Cadastral 
Bureax will be bigger at least to 15%. This gives a total 
annual income of at least 9 billion drch or $ 37 million. 
126 
The income of the other sources can not be added to this 
amount, because there is not yet such decision taken by 
HEMCO for selling the information to the private and public 
sector. If this is to be decided there is a need for special 
legislation about the ownership rights over this information 
and a cost policy has to be defined. 
4. COST-RECOVERABILITY OF THE CADASTRE 
According to the international experience, it can be said 
that traditionally there has been a recognition that the 
State has the responsibility for the provision of 
fundamental mapping. So, Cadastral systems are usally 
financed through government funding. However the 
general trend in developed countries is to seek financing 
towards other sources, such as privatisation or cost- 
recoverability. 
For the investigation of the recoverability of the N.C. 
through the recovery charge, the following consideration 
has been made. 
It is presupposed that the total of the necessary money is 
acquired through a loan from international banking 
sources, at a fixed interest rate of 6.596, repayable in 
annual instalments. 
The amount of money given in the following will be 
referred to an area of 1 hectar: 
e The compilation of the Cadastre will last for 3 years in 
total and will cost $ 100. The money for the payment of 
the responsible companies/firms should be found in 
three stages: 1/3 at the beginning, 1/3 by the end of the 
first year and 1/3 by the end of the second year. 
e In parallel with the compilation of the Cadastre, the 
other expences for the installation, instrumentation etc 
of a total of $ 149 will begin: 50% by the end of the 
second year and 50% by the end of the third year. 
e The collection of the recovery charge is expected to 
start by the end of the fourth year (one year after the 
completion of the compilation work) and will account to 
$ 251 (mean average for the whole country). 
e 80% of the owners is expected to be known by the 
completion of the compilation work for the Cadastre 
and it is expected that the recovery payment will be 
completed in three years: 70% of them will pay by the 
end of the first year, and the remaining 30% of them 
10% annually. 
e 2096 of the owners is expected to be unknown 
persons (a pessimistic suggestion) and the recovery 
payment when they appear is expected to be 
completed: for the 5096 of them during the next five 
years and for the remaining 5096 in the next two years 
after the first five. 
According to this consideration the whole system is 
completed eleven years after the beginning of the 
cadastral survey. Then there is a remaining deficit of $ 83 
per he, which accounts to 33% of the total cost per he for 
the establishment of the N.C. This amount should be 
covered by other funding, i.e. governmental investment, so 
that the N.C. to be completed. 
However, the establishment of the system is a “one off” 
cost which usually is supported by the State. On the 
contrary the maintainance of the system or the provision 
of information from the system is more often, 
internationally based on cost recovery or even designed to 
generate government revenue.
