    terrain50-cli

    CLI for parsing Ordnance Survey Digital Elevation Model files

    This is the CLI for the sister terrain50 library on npm for parsing Ordnance Survey DEM files I also implemented.

    Install

    Install via npm:

    npm install terrain50-cli --global

    Usage

    The command-line interface works on a subcommand-based system using applause-cli (another package of mine).

    Display the usage information like this:

    terrain50 --help

    If you installed it locally, you'll need to do this:

    path/to/node_modules/.bin/terrain50 --help

    Environment Variables

    Additionally, a number of environment variables are supported.

    Variable Purpose
    NO_COLOR Disables ANSI escape codes in output (i.e. coloured output). Not recommended unless you have a reason.
    QUIET Suppress all output except for warnings and errors (not fully supported everywhere yet)

    Notes

    image subcommand: --boundaries argument

    This argument's purpose is the divide the incoming data into categories so that an AI can be potentially trained on the data (e.g. water depth data, as I'm using). It takes a comma separated list of values like this:

    0.1,0.5,1,5
    

    ...and turns it into a number of bins like so:

    • -Infinity ≤ value < 0.1
    • 0.1 ≤ value < 0.5
    • 0.5 ≤ value < 1
    • 1 ≤ value < 5
    • 5 ≤ value < Infinity

    Each bin is assigned a colour. Then, for each value in the input, it draws the colour that's assigned to the bin that the value fits into.

    Read-world use

    • I'm using it for the main Node.js application for my PhD in Computer Science!
