Hello, I'm Saade from Turkey and so I'm working as an engineer at General Directorate of Land Registry and Cadastre so it's gonna be my first ever talk in FOSS event so I am a bit of excited so please pardon me. So I would like to talk about the project like briefly talk about the project that we
00:23
will develop or we are developing so firstly Turkey's national geographical information system is known as TU CBS aims to coordinate geographical information infrastructure among public institutions so it's just like established by a presentable degree and in
00:45
starting with 2011 so Directorate of General, General Directorate of Geographical Information System has handed over this mission to like maintain data and sharing and the project overview is just coordinating standard topographical maps
01:07
produced by map department of our institution so we have our own plane tool like creating orthophotos and aerial images started in 1955 so it involves photogrammetric
01:24
base map production at you know 5,000 scale covering 480,000 kilometers square and so like when we create raster data so we have some challenges so raster data presents issues such as deformation, distortion and varying quality accessing these characteristics
01:47
is crucial for automation and ensuring data accuracy so we were using Quantum.js to utilize this raster data and like coordination processes particularly on Ankara sheet
02:03
also like open source software offers flexibility and community driven support for us like to enhance project management and customization so we have successfully coordinated 1967 raster sheets demonstrating the effectiveness of the open source tools
02:24
so work is underway to publish a total of 82,000 data via web service using GeoServer the process of publishing old data has been completed and the process of publishing current data is in progress so we have also all the requirements when it comes to like
02:43
shared data and managed data so we are sharing our data using our GeoPortal that we had developed beforehand so called metadata GeoPortal so we are just making a representation of those kind of data using GeoServer again like using GeoTIFF so in the this slide so you are able to
03:05
see our web portal called Metadata. So when we use the open source approach so it just shows us it's a cost effective sustainable and accessible to broad user base and
03:21
so proposes a model for widespread adoption of this approach in a similar project so conclusions or improvements in map management process highlight the project success so like advocate for the adoption of the open source approach in the comparable project so
03:40
also like it's important step towards the digitalization of the public institutions so and thanks for listening thank you thank you
