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.

Setup

sudo pip install -r requirements.txt

Examples

generate by coordinate

# around Tokachi
python CSReliefMap.py GenerateImageByBounds --west 142.74810791015625 --north 43.25320494908846 --south 42.21224516288584 --east 143.72589111328125 --zoom 14 --workers 4 --local-scheduler

# around Tokyo
python CSReliefMap.py GenerateImageByBounds --west 139.559326171875 --north 35.77994251888403 --south 35.36217605914681 --east 140.2569580078125 --zoom 15 --workers 4 --local-scheduler

# generate each tile (curvature only)
python CSReliefMap.py GenerateImageCurvature --x 29139 --y 12936 --z 15 --local-scheduler

# generate each tile (slope only)
python CSReliefMap.py GenerateImageSlope --x 29139 --y 12936 --z 15 --local-scheduler

# generate each tile
python CSReliefMap.py GenerateImageCSReliefMap --x 29139 --y 12936 --z 15 --local-scheduler

Resizing large image to small image (experimental)

# single tile
python CSReliefMap.py resizeTileImage --x 3641 --y 1616 --z 12 --sourceZ 14 --sourceTask generateImageCSReliefMap --workers 4 --local-scheduler 

# around Tokyo
python CSReliefMap.py GenerateResizedImageByBounds --west 139.559326171875 --north 35.77994251888403 --south 35.36217605914681 --east 140.2569580078125 --zoom 10 --workers 4 --local-scheduler

Utility for coordinate picking

leaflet-areaselect

generate by japanese level-1 mesh(1次メッシュ)

python CSReliefMap.py GenerateImageByMeshCodes --meshcodes "[6341,6342]" --zoom 14 --workers 4 --local-scheduler

# resized tile map based on zoom 14 (experimental)
python CSReliefMap.py GenerateImageByMeshCodes --targetTask generateResizedImageByBounds --meshcodes "[6341,6342]" --zoom 10 --workers 4 --local-scheduler
