The data


In this chapter, a few data sources will be used as examples. All these sources are freely available on the Internet.

For the data model explanation and first processing examples, we will use the Natural Earth national borders data, specifically the Admin 0 - countries layer. It is available for download at http://www.naturalearthdata.com/downloads/10m-cultural-vectors/.

The data simplification topic will be discussed using the Czech hydrological dataset, called DIBAVOD. It is considered public information and is therefore free to download and reuse. The data can be downloaded from http://www.dibavod.cz/index.php?id=27. We'll need the following layer (download links are visible after expanding the A section): A08 - hydrologické členění - povodí III.řádu - the watershed dataset.

Note

There is also a more detailed version - the A07 dataset with fourth-order watersheds. It can be also used, but it will take more time to process.
