well-defined statement of the problem in terms, which can be 
understood clearly by people involved in the problem area. 
Problem analysis and formulation of a method of solution is 
the most difficult and crucial step. To obtain a correct and 
efficient solution to a problem, existing mathematical and 
other pertinent techniques and tools relevant to the problem 
arca must be used and whenever necessary new techniques 
must be developed. At this step, the type and organization of 
the data to be handled, the mathematical procedures are 
determined. The method of solution is expressed as a 
sequence of precisely described logical steps. Such a 
description of method of solution is called am algorithm. 
Once a method of solution formulated, the logical steps and 
the sequence of operations to be performed at each step are 
next represented in a pictorial form, which is called a 
flowchart. 
A flowchart is just a visual aid, but a computer cannot 
understand it. The method of solution must be expressed in a 
computer language to be understood by it. Many languages 
have been developed in order to communicate with the 
computers. Expressing the method of solution in terms of a 
computer language is called programming. 
The last step is to run the program on a computer to get the 
desired answers, to correct the mistakes made in formulating 
the method of solution and/or programming until valid results 
are obtained and to document all the work done so that the 
same program can be used over and over again by different 
people to solve the same problem with different data values ( 
Arkun and Gungor, 1977 ).

3.1. Material and Method 
Land Consolidation Project is carried out according to 
instructions of both General Directorate of Rural Service and 
Directorate General of Agricultural Reform. Therefore, This 
study aimed at algorithm developing benefit from Land 
Consolidation flow chart of General Directorate of Rural 
Service and flow chart symbols for algorithm preparing ( 
Iscan, 2003). 
Figure 2 shows the flow chart prepared by General 
Directorate of Rural Service applications.

3.2. Calculate of Sharing Ratio of Common Area and 
Land Area Given Back to Owner 
All parcels are necessary to benefit from canal and road 
network. Therefore, Project area is planed with suitable and 
enough canal and road system. After this planning, canal and 
road areas are calculate. 
This calculated area is given from registration external lands. 
Latter, area is reduced proportional land value given back to 
owner. Remaining area is registered in the name of Village 
Legal Personality. 
Equation (1) is used to compute sharing ratio of common 
area.

(OTKPO) 9 ———— (1) 
h 
Where; 
OTKPO= sharing ratio of common area, 
h = total area of cadastre parcels , 
r = total area of blocks, 
a = registration external lands, 
According to OTKPO, Cadastre parcels are necessary to read 
and gather from formed database. Latter, total areas of blocks 
are necessary to calculate from block corner coordinate. All 
data for Equation (1) are ensuring to calculate and computer 
entering registration external lands. 
Terms shows below is used in the Algorithm 1; 
h = total area of cadastre parcels, 
r = total area of blocks, 
a = registration external lands, 
I = loop, 
K = block number, 
M = number of block corner, 
X, Y = block corner coordinates, 
T = block area, 
F = area of cadastre parcel, 
N = number of cadastre parcel, 
OTKPO = sharing ratio of common area, 
OTKP = sharing of common area, 
GF = land area given back to owner,
