A platform for building spatial data infrastructure and deploying browser based GIS.

The GC2/Vidi framework helps you build a spatial data infrastructure quickly and easily. Powered using open source components for a scalable solution focused on freedom rather than fees.

GC2/Vidi comprises two software projects:

  • GC2 – makes it easy to deploy PostGIS, MapServer, QGIS Server, MapCache, Elasticsearch, GDAL/ogr2ogr. And offers an easy-to-use browser application to configure the software stack.
  • Vidi – a modern take on browser GIS. It is the front-end client for GC2.

Core features

  • GC2 enables you to:

    • Import into PostGIS from different spatial vector and raster formats like ESRI Shape, MapInfo TAB/MIF, GeoJSON, GML, KML, ESRI fileGDB, GeoTIFF and ACS. And non-spatial formats like CSV and MS Access.
    • Use roles, versioning and workflow management to take control over your data.
    • Make maps using MapServer or QGIS Server and scale to many users with the help of MapCache.
    • See and edit your data in applications that supports the OWS standards.
    • Use PostGIS SQL language as a web service and get the result as GeoJSON, CSV or Excel.
    • Get data from PostGIS indexed in Elasticsearch by a click on a button.
    • Deploy the whole software stack using Docker.
  • Vidi enables you to:

    • Display GC2 layers as either non-tiled, tiled or vector.
    • Query data using geometry and buffers.
    • Add drawings with measurements, styles and labels.
    • Print scaled PDF maps based on Mustache templates.
    • Save, restore and share projects. A project comprises the extent of the map, which background map is visible and which layers are turned on, which filters are applied as well as your drawings.
    • Write your own modules using an extension mechanism.
  • Vidi is a Progressive Web App (PWA), which:

    • Starts without network.
    • Caches vector layers in browser, so they can be used without network.
    • Partial caches tiled baselayers in browser for use without network.
    • Edits data without network. Transactions are queued and submitted when online again.
