Last change on this file since 13733 was 13733, checked in by wiktorn, 6 years ago

Imagery definition refactor

Extend imagery definitions by:

  • allowing setting default layers for WMS_ENDPOINT and WMTS
  • allowing setting minimum expires time for tile for this imagery
  • allowing setting custom headers that will be sent for all requests

(get map, get capabilities) for this imagery

Additional changes in code:

  • use TileJobOptions to pass miscellaneous options to loaders
  • refactor WMSImagery to use SAX parser

See: #15981, #7953, #16224, #15940, #16249
  • Property svn:eol-style set to native
