fig congress 2018 - Spatial datamanagement from local to center
Dr. Emin Bank
The importance of spatial data and the market of spatial sector are increasing day by day. The basic aim in the implementation of spatial data in a country is to have that data to be used as efficiently and economically. For this purpose, it is aimed to have the spatial data produced once and to be used by multiple users/institutions for many times as well as having the distributed data as integrated and saving up in data production and maintenance costs. It is possible to collect the spatial data under three main titles. The first title includes some basic base data like maps, plans, aerial photos and satellite images produced as based on horizontal and vertical geodesic network of the country. The second title includes manmade data and the infrastructure data like address, property, building, road, electric/water/sewage/rain water and finally the third titles includes the natural source data like forest, water, geology, landscape, environment, mine, climate, and protected areas. Natural source data is more static when compared with manmade data. There are institutes that responsible of gathering and archiving of the basic base and natural source data and that data is carried to the electronic environment and opened to web share through these institutes. The data called as manmade data is the one which is produced and updated in the transit process of rural to urban area. That data is produced through the projects applied by Local Government and opened to share as generating the country wide inventory by the institutes responsible in the center. It is more dynamic than the other data groups and needed constant development and update. It is too important to develop an inventory for the data produced by Local Government in the center authorities through an automation process to have the SDI updated all the time. For sample, each day many rural areas are zoned for housing, thousands of buildings got licenses, new parcels are being created and new roads or network systems are being developed. So, to create the country wide updated inventory of that data, distributed-center system integration should be provided.
