ABSTRACT: 
In Turkey cadastral works and registrations in the means of establishment of determination parcel boundaries and owners have been 
completed as 99 % for urban area and 88% for rural area by General Directorate of Land Registry and Cadastre of Turkey (GDLRC). 
Rural areas which are mostly mountainous and forestry are remaining. In most of the cadastral works completed areas are expected to 
be renovating in cadastral means. 
Currently many projects are started with related to cadastral works and land registration. One of them is MERLIS (Marmara 
Earthquake Region Land Information System). Cadastre Renovation and Land Management (A4 Component of MERLIS) financed 
by the World Bank in Marmara Earthquake Region. Another one is ARIP (Agricultural Reform Implementation Project). The aim of 
project is to design and form the NRF (National Registry of Farmers) system under the Direct Income Support (DIS). This sub- 
component of the DIS is aimed supporting GDLRC to increase the inclusion of agricultural areas that are not yet in computerized 
part of the cadastre. For the realization of this aim, true and reliable Cadastre and Land Registry information is needed in 20 
provinces, especially in Eastern Anatolia and Southeastern Anatolia. These projects are required land information such as parcel 
boundary, owner, area etc. To get such information cadastre and land registry must be completed and served in digital medium. 
These paper presents an investigation on comparison to 1/5000 scale digital photogrammetric measurements and satellite image 
measurements of the same cadastral boundary points. Initial aim was to compare with real time GPS measurements, unfortunately 
winter conditions in the test area are prevented us doing GPS measurements. Before the Congress GPS and total station 
measurements probably will be carried out. Results of the tests have been evaluated as accuracy, time and costs. 
l. TEST AREA SPECIFICATION 
Test area is SIVAS-Sarkisla region which is located on eastern © Test area also reflects typical characteristics of 
part of Turkey have been chosen. Size of test area is 10*10 km uncompleted cadastral areas. 
and has same characteristic of areas which is uncompleted 
initial cadastre. Main characteristics specifications of test area After densification of : geodetic points in test area, aerial 
are; photographs have been taken in year 2000. Photogrammetric 
standard map production has been completed in 1/5000 scale. 
* Some part of the area flat, plain and somehow Terrestrial map verification has not been completed yet. As 
mountainous, undulating and rural areas, comparison critters unverified photogrammetric data and 
e Some part of area open and somehow forestry, satellite based data were used. In addition terrestrial based data 
e Very dense parcel, infrequent parcel distribution and in the measured by RTK GPS were planned to use a comparison but it 
rural area forestry related parcels available is not completed because of winter season.
