Updating Transportation Data Theme of National Spatial Data Infrastucture with Participatory Geographic Information

Abstract

The purpose of this article is to examine the 'transport' geographic data theme of the Turkish National Geographic Information System (TUCBS) Project which is updated with a participatory approach. In this context, the results of the survey conducted with the representatives of the institutions, which provide a better understanding of the geographical data production and sharing status of the institutions, are analysed. In this study, similarities and differences between the TUCBS transport theme that is initially determined in 2013 and updated in 2018 with the participatory approach is also identified. Within the scope of the updates, it is determined that the number of feature types increased from 50 to 131, the number code lists increased from 33 to 42 and 26 feature types and 17 code lists remain common in both studies. It is necessary to update the spatial data infrastructures with a participatory approach, however, it is still not at the desired level yet. It is foreseen that the contribution of all the stakeholders in standardizing the transportation theme will make the standards be more operational.
