1.5. How data is managedΒΆ

Geodata in Web GIS is managed with resource system. At the moment there are following types of resources:

Resources for managing local sources of geodata:

Resources for managing external sources of geodata:

  • Basemap (created to add external basemaps to Web maps)

  • PostGIS connection (created to connect to external PostGIS database)

  • PostGIS layer (created to connect to the specific table with geodata through existing PostGIS connection)

  • WMS connection (created to connect to an external WMS server)

  • WMS layer (created to connect to the specific raster layers through existing WMS connection)

  • TMS connection (created to connect to an external TMS server)

  • TMS layer (created to connect to the specific layers using an existing TMS connection)

Resources for displaying and publishing geodata:

  • Style (special type of resource, created inside Raster layers, Vector layers and PostGIS layers to add them to Web map or publish using WMS protocol)

  • Web map (created to display Raster layers, Vector layers, PostGIS layers and WMS layers on the map through built-in web client)

  • WFS service (created to publish Vector layers and PostGIS layers using WFS protocol)

  • WMS service (created to publish Raster layers, Vector layers, PostGIS layers and WMS layers using WMS protocol)
