    Article

    Data and GIS

    Catalogues and maps of open data: geodata sources, incident reports geocoded and served from one registry.

    The category holds 47 original repositories, written most often in Ruby, JavaScript, Elixir and Shell. Featured: Data Atlas and Crisis map.

    Key concept: GIS.

    How categories are made: nobody assigns them by hand. A repository falls into a category when its name, description or topics match the rule’s keywords, otherwise its primary language decides; forks and mirrors never count as the owner’s work.
