More than a year ago i introduced an approach to process waterbody data for the purpose of generating a generalized worldwide river network. This method required quite a lot of ressources in processing so i did not reprocess it since … Continue reading

In my previous work on generalization of geodata for map rendering, including coastlines, waterbodies, settlements and relief i have so far not covered administrative boundaries. The main reason is boundaries are very tricky in this regard. The vast majority of … Continue reading

I have written about and demonstrated the generalization of data for natural features in a map like coastlines, waterbodies and glaciers. Artificial elements have so far not been included there. The most obvious starting point are the human settlements. I … Continue reading
