Today, the amount of spatial data produced by users on the web is increasing rapidly day by day. This, of course, makes spatial data on the web into an important source of information especially for the development of spatial applications. Particularly with the open data policy, the spread and success of crowdsourced initiatives has prompted spatial data producer institutions and organizations to evaluate the possibilities of using crowdsourced geographic information in data collection. In this context, national mapping agencies either use open map resources created with a crowdsourcing approach to update their databases or develop mobile and web applications to collect data with a volunteered geographic information approach. From this point of view, in this study, POI data determined as part of the national mapping agency applications have been extracted from OpenStreetMap, Wikimapia and GoogleMaps map services and the differences between data sources have been assessed.

Kitle Kaynak POI verilerinin Çıkarılması

Öz

Günümüzde web üzerinde kullanıcılar tarafından üretilen konumsal verinin miktarı her geçen gün büyük bir hızla artmaktadır. Bu da, özellikle konumsal uygulamaların geliştirilmesi için web üzerindeki konumsal verileri önemli bir bilgi kaynağı haline getirmektedir. Özellikle açık veri politikası ile birlikte kitle kaynak girişimlerinin yaygınlaşması ve başarısı, konumsal veri üreticisi kurum ve kuruluşların veri toplamada kitle kaynaklı coğrafi bilgileri kullanma olasılıklarını değerlendirmeye sevk etmiştir. Bu bağlamda ulusal harita kurumları, veri tabanlarını güncellemek için ya kitle kaynak yaklaşımıyla oluşturulan açık harita kaynaklarını kullanmakta ya da gönüllü coğrafi bilgi yaklaşımıyla veri toplamak için mobil ve web uygulamaları geliştirmektedir. Bu noktadan hareketle, Harita Genel Müdürlüğü uygulamaları kapsamında belirlenen POI verileri, OpenStreetMap, Wikimapia ve GoogleMaps harita servislerinden çıkarılarak veri kaynakları arasındaki farklılıklar irdelenmiştir.
