Salih Yalcin
I worked as an Android Developer and Engineer at the Map Department of the General Directorate of Land Registry and Cadastre in Türkiye, bringing over eight years of expertise in app development and geospatial sciences. During my time, I led innovative projects to smoothly integrate technology into land registry practices.
Starting my career in 2014, I played key roles in well-known companies like Getir in Ankara and KAYAK in Berlin, making significant contributions to Android development and improving map functionalities.
Aside from my professional roles, I kept things busy at GISLOG Studios, where I explored new technologies and released apps with over 200K downloads on my Google Play account.
My educational journey included being a Geomatics Engineering Ph.D. candidate at Istanbul Technical University, specializing in smart city applications. With a master's degree in Geodesy and Geoinformation Science from Technische Universitat Berlin and another in Geographical Information Technology from Istanbul Technical University, my academic background added depth to my practical experience.
As a conference speaker, I brought a unique mix of technical expertise and real-world application, sharing insights into the dynamic intersection of Android development, geospatial sciences, and land registry advancements.

In our country, coordination among public institutions for the Turkey’s National Geographic Information System (NSDI) (Türkiye Ulusal Coğrafi Bilgi Sistemi - TUCBS) and its infrastructure, the establishment of goals and strategies, the generation and maintenance of geographic data within the thematic areas of geographic information, and ensuring its currency, management, use, access, security, sharing, and distribution are determined by the procedures, principles, and standards to be developed with the Presidential Decree No. 49.
This proposal covers the project for coordinating Standard Topographic Maps produced by the Map Department of General Directorate of Land Registry and Cadastre, highlighting significant developments in map management processes and the successes of the project, along with the detailed use of open-source software. The Department, through its photogrammetric base map production at a 1/5000 scale since 1955, examines efforts to digitize a 480,000 km² dataset. The characteristics of raster data, focusing on deformation, distortion, and quality issues in scanned data at different resolutions, are investigated to assess their suitability for automation. The testing conducted within the project includes the coordination processes using QGIS on the Ankara 1/250,000 sheet, emphasizing the contribution of open-source software to the project. The flexibility and community-driven development of open-source software have facilitated more effective project management and customization of the software. Test results indicate the successful coordination of 1,967 raster sheets and demonstrate the feasibility of more extensive testing through remote working methods.
The proposal also dives into institutional requirements related to 1/5000 sheet demands, such as registry needs, storage requirements, usage through the Metadata GeoPortal (Harita Bilgi Bankası – HBB), and web presentation. The management of open-source GeoTiff files used in the presentation with GeoServer is particularly emphasized, illustrating how storage needs change during the presentation. The use of open-source software is highlighted for its cost-effectiveness, sustainability, and increased access to a broad user base, proposing a model for the widespread adoption of this approach in similar projects.
In conclusion, this work emphasizes improvements in the map management processes of the General Directorate of Land Registry and Cadastre and the successes achieved in the coordination of Standard Topographic Maps, advocating for the adoption of this open-source approach in comparable projects.
