README toposplit - Split big topojson files into a file for each object. CURRENT VERSION 0.0.4 This is pretty much just a script I was writing for a very specific project, so I don't know how fully I will flesh this out, hence the very early version number. See CHANGES for more about each version. The EXAMPLE section describes how to use the demo, which is a pretty thorough example shell script that is probably just as effective as a tutorial would be. INSTALL from repo: npm install https://github.com/jakekara/toposplit -g from npm npm install toposplit -g NPM PAGE https://www.npmjs.com/package/toposplit USAGE toposplit --input INPUT_FILE[--outdir OUTPUT_DIRECTORY | --feature FEATURE_TO_SPLIT] --input INPUT_FILE INPUT_FILE is the json file you want to split --outdir OUTPUT_DIRECTORY OUTPUT_DIRECTORY is the directory you want the files to be stored in --feature FEATURE_TO_SPLIT This is for generating a file from only one object This option supercedes --outdir. EXAMPLE The demo dir contains demo.sh, which downloads a Census block file, splits it into layers using mapshaper, and then uses topojson to split that into separate files. NOTE: This demo requires wget (brew install wget) and mapshaper (npm install -g mapshaper) To use it, install toposplit, and then git clone this repository into some_dir $ git clone https://github.com/jakekara/toposplit.git cd into the demo folder $ cd toposplit/demo Run the demo script: $ chmod 755 demo.sh $ ./demo.sh ABOUT This is my first node program and package. I'm surprised this feature wasn't in the topojson utilities Mike Bostock wrote or mapshaper.
