an interactive cli/library toolkit to interact with geojson via cli, primary for optimization, mapbox-prefer format
- reduce size 50% by removing precision from 15 to 6 in some polygon geojson.
- remove/split properties that are not used.
- add
indexproperty to each feature for mapbox-prefer format. reduce frontend processing time. - compression with gzip(
.gz) or zstd (.zst) for smaller file size.
given a geojson file, the toolkit will create a set of geojson combined a set of operations.
given input.geojson
| operation | description | file_example_name |
|---|---|---|
| reduce precision to 6 precision or ~10 cm | reduce the precision of coordinates | input.10cm.geojson |
| split properties | split properties that are not used. | input.10cm.noproperty.geojson, input.propertyonly.geojson, input.10cm.indexonly.geojson |
| add index | add index property to each feature | input.10cm.index.geojson |
| compression | compress with gzip and zstd | _all_above_.geojson.gz, _all_above_.geojson.zst |
