Feature Description

SimpleJSON (*.json) is a proprietary data format supported by SuperMap software. Similar to GeoJSON, it uses key-value pairs as data type. Supported geometry types include points, lines, and polygons. Features in SimpleJSON contain both geometry and their attributes. SimpleJSON data consists of two files: (*.json) and (*.meta). The (*.meta) file stores metadata information including geometry type, projection, and selected fields; while the (*.json) file contains member information of the data.

A single-file SimpleJSON (*.json) contains both a (*.json) and a (*.meta) file. For SimpleJSON Folder data, one folder corresponds to one (*.meta) file. When selecting files for import, the program defaults to choosing (*.json) files and folders to open data.
