Topic name: Automated Generalisation in Reality
Generalisation of spatial data set is the process used to reduce complexity and density of objects according to the scale, while cartographic generalisation should resolve cartographic conflict (e.g. overlaps) to obtain readable map. Traditionally cartographers this works are doing manually in most of the countries. But unfortunately the process is slow and expensive.
More than 10 years Lithuania maintenance of high quality core spatial data set at scale up to 1:10.000 (GRPK). Therefore it was one of the reasons to approach automatic generalisation. After successful research of possibilities to make automatic generalisation of GRPK, Lithuania decided to invest in innovative cartographic solutions. 4 technologies for preparing DLM and DCM at scale 1:50.000 were developed until 2018: 2 for civilians according to the national needs and other 2 separately to Lithuanian militaries according to NATO standards for topographic data/maps. These technologies can change work of cartographers, but not prohibit manual correction of the results if cartographer wants or needs to do that.
Most of us use ArcGIS possibilities in our daily work. All mentioned technologies were developed mostly using geoprocessing tools and model builder as well. This presentation will cover overview of Lithuanian technologies, ArcGIS possibilities and challenges in automatization processes, and requirements for staff needed for implementing solutions.
