At Saudia.xyz service we use OpenStreetMap and a few other open and public domain sources to create regularly updated spatial datasets for Saudi Arabia.
The datasets are provided in ESRI Shapefile, ESRI Geodatabase, Mapinfo TAB, GeoJSON, PBF, OSM (XML), SQL (PostgreSQL), CSV and PDF formats and can be used in most of the existing GIS.
All datasets at Saudia.xyz are published under the Open Database License (ODbL).
Data management tools built into Saudia.xyz allow for integrated creation of data, metadata, and map visualizations. Each dataset in the system can be shared publicly or restricted to allow access to only specific users. Social features like user profiles and commenting and rating systems allow for the development of communities around each platform to facilitate the use, management, and quality control of the data the Saudia.xyz instance contains.
It is also designed to be a flexible platform that software developers can extend, modify or integrate against to meet requirements in their own applications.
