DESCRIPTION:The National Land Survey of Finland has renewed its topographic
  data management system. The new system is built on QGIS and utilizes Post
 GIS databases for data storage. The development process has taken four yea
 rs\, and the first implementation will take place this spring. The system 
 will be used by over 100 operators\, providing them with tools for data ma
 nagement. The goals of the renewal are: \n\n- Utilization of new technolog
 ies and standards \n- Advancement in the transition from producing map dat
 a to producing spatial data \n- Enhancement of the quality and timeliness 
 of data \n- Enhancement of the production through automation and better to
 ols\n\nDuring the first two years of development the focus was on concurre
 nt data management and on the integration of the stereo mapping tools (pro
 prietary). Data management has been implemented as a separate backend serv
 ice for QGIS. After that\, we have implemented quality assurance tools to 
 maintain the logical consistency of the features concerning attributes\, g
 eometries\, and topology. Furthermore\, we have implemented tools for hand
 ling elevations and made several improvements to facilitate better data ma
 intenance.\n\nIn this presentation\, I will discuss the solutions implemen
 ted in the new system\, including quality management tools and topological
  editing features. I will explain how these tools enhance the accuracy and
  reliability of maintaining topographic data using QGIS. Additionally\, I 
 will share the successes and challenges we have encountered during the dev
 elopment process and in the early stages of production use.
