Summary

Add WMS Time support in QGIS server

Proposed Solution

Add in the vector layer properties / QGIS Server a section named WMS Time with the following attributes:

• Field: Combo boy with disable and compatible fields
• Advance => Extent: text field with e.g.: min1/max1/res1,min2/max2/res2, Default: text field
• Resolution: integer field combo with years Y, months M, days D, time T, hours H, minutes M, seconds S
  It we want to put more advance resolution like: P1M10D or PT1.5S use the advance field
• Extent: from date (time) picker to date (time) picker
• Default: date (time) picker

Impact the WMS server:

• GetCapabilities

• Add the Dimensions for the vector layers
• Copy the Dimensions for the WMS layers

• GetMap and GetFeatureInfo for vector layers

• Add a Filter Expression eventually a Filter SubsetString for the Postgis layers

• GetMap and GetFeatureInfo for WMS layers

• Just a pass throw of the TIME parameter

Points to investigate:

• what's don in the time manager (client part) https://plugins.qgis.org/plugins/timemanager/
• should we have a solution that manage all the Dimensions...
• should we add the settings int the server part or in a new tab of the layer for an eventual implementation in QGIS desktop

Next steps:

• Also avalable for WMTS layers
• Have a GUI in QGIS desktop like the TimeManager
• Also support the elevation spec
