Modernising topographic mapping in Cyprus

In December our sister organisation in Cyprus, the Department of Lands and Surveys, welcomed us to learn from our experience in modernising topographic mapping processes. We offered a practical 3-day training course on topographic map production.  

Challenges in map production

The course covered theoretical backgrounds, implementation methodologies, and practical demonstrations. We guided participants through the developments and changes in management practices and workflows for topographic map production. We discussed how to handle different challenges, such as budget cuts, NSDI restructuring, and staff reductions. 
 

5 years of effort in 2 days

We also looked at emerging technical opportunities. Since 2011, Kadaster has transformed its topographic map production, using modern automatic generalisation techniques. As senior adviser Magdalena Grus put it: “What if 1 click could turn 5 years of effort into 2 days? Let’s aim for that.” Furthermore, we introduced LEAN methodology, open data policies and applications of these new data. 

Key takeaways

After 3 intensive days, our colleagues from Cyprus had gained knowledge of: 

  • the main steps involved in automated generalisation, including the importance of input data (topology and data cleansing), pre-processing, quality and purpose of output data.
  • multi-resolution data representation techniques. For instance scale-specific symbolisation and geometry transformation.
  • the key components of quality assurance processes prior to generalisation. Such as completeness, positional accuracy, attribute consistency and topological correctness.
  • practical examples of generalisation workflows and implementations.
  • translating Kadaster's approach to its own organisational context by contributing to a roadmap for implementing generalisation at DLS.
