However, in the forest areas the cadastral works are still carried out under a different law next (No. 6831) undertaken by General Forest Directorate [5].2.2. selleck chemical Abiraterone Technical ProcessFrom a technical perspective, Inhibitors,Modulators,Libraries Turkish cadastre has two different cadastral periods. These are the written and linear cadastre periods, respectively.2.2.1. Written Cadastre PeriodWritten cadastre means that cadastral information is expressed in words instead of linear data. In the written cadastre period, technical infrastructure was not sufficient for the visualization of the position based data and also there were not enough technical staff to carry out this process.
In the written cadastre, real estate boundaries were identified in the land title document with the features to the north, south, east and west of the property, for example there is a village road to the south, a river to the north.
Such studies had been carried out from Ottoman Empire period to 1934. These documents are Inhibitors,Modulators,Libraries still used as property evidence in Inhibitors,Modulators,Libraries the areas where linear cadastral works have not yet been carried out [6].2.2.2. Linear Cadastre PeriodWith the introduction of arithmetic and geometric applications, Inhibitors,Modulators,Libraries cadastre gained a technical perspective. In this context, the Turkish linear cadastral works were initiated in the early 1990′s. The linear cadastre period can be grouped into four categories: graphic, classic, photogrammetric and electronic tachometry methods.
a)Graphical Method: In Turkey, this was the first type of cadastral work; parcel corner coordinates were surveyed with chain surveys based on the polygons which exist on the ground but having no coordinate values (Figure 1).
Thus, the Inhibitors,Modulators,Libraries parcel Inhibitors,Modulators,Libraries surveying values derived from this method generally have no control procedures and the bases produced by graphical method do not have sufficient quality for today’s requirements. In other Inhibitors,Modulators,Libraries words, most of these bases have ground-sheet inconsistencies. The bases produced by graphical method constitute 20% of the whole cadastral bases in Turkey.Figure 1.A sample cadastre map produced by the graphical method.b)Classical Methods: These are generally orthogonal and tachometric methods. Those works carried out before 1968 were based on polygons, later they were based on localized land surveying triangulations.
While, the orthogonal method was used in urban areas under Law No. 2613, Inhibitors,Modulators,Libraries the tachometric method was used in rural areas under Law No.
766. After 1974, based on national land surveying triangulation Entinostat network these surveys became widespread. The obligation to produce cadastral bases in national overnight delivery coordinate system was put into practice after 1993.c)Photogrammetric Method: After 1950, this method was frequently used in order to accelerate cadastral work. The photogrammetric Anacetrapib method was used in the selleck chemicals Lenalidomide areas where land cover and topography is suitable.
