Sorting Rules Example

When running the layers command in flat mode (--mode flat), it is possible to sort the layers in the output by passing a path to a JSON file containing, sorting rules. See below for an example a sorting rules JSON file (use for example with: ngr-spider layers --sort sorting-rules.json -n 20 -m flat --pretty -p "OGC:WMS,OGC:WMTS" output.json):
