random-geojson

random-geojson is a command-line tool written in Rust for generating random GeoJSON geometries. It supports multiple geometry types (Point, LineString, Polygon, and All) and coordinate systems (WGS84, WebMercator, 4326, 3857). The tool can generate a collection of random features with customizable properties and output them to a file in either compact or pretty-printed JSON.

Features

• Generates random GeoJSON FeatureCollection
• Supports Point, LineString, Polygon, and All (all geometry types)
• Output geometries in either WGS84 (EPSG:4326) or Web Mercator (EPSG:3857)
• Randomized properties with string, number, and boolean values
• Configurable number of features and properties
• Output to a file in compact or pretty-printed format

Usage

random-geojson [OPTIONS]

Options

• --num-properties <NUM_PROPERTIES>
  Number of properties to generate for each feature (default: 0)

• --length <LENGTH>
  Number of features to generate (default: 100)

• --geometry-type <GEOMETRY_TYPE>
  Type of geometry to generate. Possible values: Point, LineString, Polygon, All (default: All)

• --coordinate-system <COORDINATE_SYSTEM>
  Coordinate system to use. Possible values: WGS84, WebMercator, 4326, 3857 (default: WGS84)

• --pretty
  Output GeoJSON in pretty-printed format (default: false)

• --output-file <OUTPUT_FILE>
  File name to save the generated GeoJSON (default: random.geojson)

Example

Generate 10 random points in WGS84 with 3 properties per feature and pretty-printed output:

random-geojson --length 10 --geometry-type Point --num-properties 3 --pretty -o mydata.geojson

Output

The tool generates a valid GeoJSON FeatureCollection with the specified number of features and properties. Each feature has a unique UUID as its id, random geometry, and random property values.

To do

• Add examples
• Allow fine-grained control over generated property types and values
