CS Relief Map Tile Image Generator

An one stop tile image generator of CS Relief Map written in Python, integrated with Luigi and numpy.

What is CS Relief Map (CS立体図) ?

The "CS Relief Map" (CS立体図) is a terrain visualization method with high visibility of Curvature and Slope. This was proposed by Nagano prefecture forest center (長野県林業総合センター).

This implementation is based on these articles.
