topotrim

A simple tool to trim a topoJSON file based on values of a particular property and output the result to a new file

Usage:

topotrim -m property -s match -i source.json -o output.json

Where:

  • -m is the objects geometry property to match on. (defaults to POA_CODE16 because that is what i use it for :D)
  • -s is the match criteria string (defaults to 7 because again that is what I'm using it for)
  • -i is the input json file
  • -o is the output json file (defaults to output.json)

ToDos:

  • The matching property is string only. Modify this for multiple types
  • The match criteria is begins with only. Modify this to be regexy
