Schema

• H: Represents HANREI_C (See 凡例コード for details)
• C: Represents {DAI_C}{CHU_C}
• S: Represents {SHOKU_C} with original additional codes

Create mapbox tilemaps

1. Get vg67 shapefiles from Biodivercity Center of Japan

http://gis.biodic.go.jp/webgis/sc-023.html

2. Unzip all the archives

Path should be like vg67/vg67_01/shp644441/p644441.shp or vg67/vg67_22/shp523852/shp523852/p523852.shp.

3. Convert shapefile to geojson

See geojsoner.

and Run:

# Insert a newline after each file
$ awk '{print $0}' ./data/geojson/*.geojson > data/geojson-lines/vg67_sai.geojsonlines

This merge improves tippecanoe performance by 2x.

5. Trim geojsons for lower zooms

See trimmer

and Run:

# Insert a newline after each file
$ awk '{print $0}' ./data/geojson-trimmed/chu/*.geojson > data/geojson-lines/vg67_chu.geojsonlines
$ awk '{print $0}' ./data/geojson-trimmed/dai/*.geojson > data/geojson-lines/vg67_dai.geojsonlines

6. Create label symbols

See labeler

and Run:

# Insert a newline after each file
$ awk '{print $0}' ./data/geojson-trimmed/sai-labels/*.geojson > data/geojson-lines/vg67_sai_labels.geojsonlines

7. Create xyz style mvt tile files

Install felt/tippecanoe and run:

$ tippecanoe -Z10 -z12 -d14 -l vg67_sai --no-simplification-of-shared-nodes --no-tile-compression --no-tile-size-limit --no-feature-limit --no-tiny-polygon-reduction --name="vg67_sai" --description="1/2.5万植生図GISデータ(環境省生物多様性センター) http://www.biodic.go.jp/kiso/vg/vg_kiso.html を加工して作成" -e data/mvt/sai/out/ --force --read-parallel data/geojson-lines/vg67_sai.geojsonlines
$ tippecanoe -Z8 -z9 -l vg67_chu --no-simplification-of-shared-nodes --no-tile-compression --no-tile-size-limit --no-feature-limit --no-tiny-polygon-reduction --name="vg67_chu" --description="1/2.5万植生図GISデータ(環境省生物多様性センター) http://www.biodic.go.jp/kiso/vg/vg_kiso.html を加工して作成" -e data/mvt/chu/out/ --force --read-parallel data/geojson-lines/vg67_chu.geojsonlines
$ tippecanoe -Z6 -z7 -l vg67_dai --no-simplification-of-shared-nodes --no-tile-compression --no-tile-size-limit --no-feature-limit --no-tiny-polygon-reduction --name="vg67_dai" --description="1/2.5万植生図GISデータ(環境省生物多様性センター) http://www.biodic.go.jp/kiso/vg/vg_kiso.html を加工して作成" -e data/mvt/dai/out/ --force --read-parallel data/geojson-lines/vg67_dai.geojsonlines
$ tippecanoe -Z12 -z12 -d15 -l vg67_sai_labels --no-tile-compression --no-tile-size-limit --no-feature-limit --name="vg67_sai_labels" --description="1/2.5万植生図GISデータ(環境省生物多様性センター) http://www.biodic.go.jp/kiso/vg/vg_kiso.html を加工して作成" -e data/mvt/sai-labels/out/ --force --read-parallel data/geojson-lines/vg67_sai_labels.geojsonlines

• -d14: Keep high resolution on the max zoom
• -l: Merge all the geojson files into one layer
• --no-tile-compression: Required for mapbox / QGIS
• --no-simplification-of-shared-nodes: Cleanful polygon simpify (No overlaps, No empty spaces)
• --no-tiny-polygon-reduction: Disable small polygon show up as a square polygon

8. Upload maptile files to some block storage

For example...

$ cp rclone.conf.example rclone.conf
$ edit rclone.conf
$ docker run --rm -it -v ./rclone.conf:/config/rclone/rclone.conf:ro -v ./data/mvt/dai/out:/data/source:ro rclone/rclone copy /data/source/ r2://{r2 bucket}/vg67/mvt/dai/ --no-check-dest --s3-no-check-bucket --progress
$ docker run --rm -it -v ./rclone.conf:/config/rclone/rclone.conf:ro -v ./data/mvt/chu/out:/data/source:ro rclone/rclone copy /data/source/ r2://{r2 bucket}/vg67/mvt/chu/ --no-check-dest --s3-no-check-bucket --progress
$ docker run --rm -it -v ./rclone.conf:/config/rclone/rclone.conf:ro -v ./data/mvt/sai/out:/data/source:ro rclone/rclone copy /data/source/ r2://{r2 bucket}/vg67/mvt/sai/ --no-check-dest --s3-no-check-bucket --progress
$ docker run --rm -it -v ./rclone.conf:/config/rclone/rclone.conf:ro -v ./data/mvt/sai-labels/out:/data/source:ro rclone/rclone copy /data/source/ r2://{r2 bucket}/vg67/mvt/sai-labels/ --no-check-dest --s3-no-check-bucket --progress

$ docker run --rm -it -v ./rclone.conf:/config/rclone/rclone.conf:ro -v ./data/hanrei/descriptions:/data/source:ro rclone/rclone copy /data/source/ r2://{r2 bucket}/vg67/hanrei/descriptions/ --no-check-dest --s3-no-check-bucket --progress
$ docker run --rm -it -v ./rclone.conf:/config/rclone/rclone.conf:ro -v ./data/hanrei/images:/data/source:ro rclone/rclone copy /data/source/ r2://{r2 bucket}/vg67/hanrei/images/ --no-check-dest --s3-no-check-bucket --progress

$ docker run --rm -it -v ./rclone.conf:/config/rclone/rclone.conf:ro -v ./data/page:/data/source:ro rclone/rclone copy /data/source/ r2://{r2 bucket}/ --no-check-dest --s3-no-check-bucket --progress

Debugging

Run:

$ python3 -m http.server -d data

• Open http://localhost:8000/page/ on your browser to view the map
• Set http://localhost:8000/mvt/sai/out/{z}/{x}/{y}.pbf with max zoom level 12 to view the vector tiles on QGIS
