Changeset 8568 in josm for trunk/src/org/openstreetmap/josm/data/projection

Timestamp:

2015-07-04T22:52:23+02:00 (9 years ago)

Author:

Message:

Basic WMTS support.

• added information about units and to_meter to EPSG projection definitions (needed for WMTS)
• added WMTSTileSource and WMTSLayer classes
• a bit of cleanup of AbstractTileSourceLayer and align so it will work properly with WMTS tile definitions
• added Imagery Preferences panel for WMTS and icon for button
• added removal of wms: / tms: / wmts: prefix, if user will paste them into the field
• CachedFile - added possibility to send custom headers with request
• added support for unit and to_meter in CustomProjection
• AbstractTMSTileSource cleanups (change of Coordinate to ICoordinate)
• moved JCSCachedTileLoaderJob.read() to Utils

Addresses: #10623

Tested with Polish WMTS service proivders, Walonnie needs still some debugging, as it is not working right now.
