cjseq

A program to create/process/modify CityJSONSeq files, and convert CityJSON.

Installation/compilation

To install the binaries on your system easily

1. install the Rust compiler
2. cargo install cjseq

To compile the project (and eventually modify it)

1. install the Rust compiler
2. git clone https://github.com/cityjson/cjseq.git
3. cargo build --release (this will ensure the binaries are compiled too)
4. ./target/release/cjseq --help

Usage

cjseq can either take its input from stdin, or from a file. It always outputs to stdout the results (either a CityJSON object or a CityJSONSeq stream).

CityJSON => CityJSONSeq

cjseq cat -f myfile.city.json > myfile.city.jsonl will convert the file myfile.city.json to a CityJSONSeq stream and write it to the file myfile.city.jsonl.

cat myfile.city.json | cjseq cat will output the stream to stdin.

CityJSONSeq => CityJSON

cat ./data/3dbag_b2.city.jsonl | cjseq collect > 3dbag_b2.city.json

filter CityJSONSeq

cat myfile.city.jsonl | cjseq filter --bbox 85007 446179 85168 446290 > mysubset.city.jsonl

Input constraints

1. the input CityJSON/Seq must be v1.1 or v2.0 (v1.0 will panic)
2. the input JSON but be CityJSON schema-valid, use cjval
