ceramic 0.9.5

• Patch for CRAN when mapbox not available.

• Add zero block code for 401 error (think that means we have no valid key, but manifests as cache problem).

ceramic 0.9.0

• Added a suite of Tasmap sources for ‘cc_location()’.

• Removed bad-practice use on terra internals, thanks to Robert Hijmans.

ceramic 0.8.0

o BREAKING CHANGES

• base_url is now ignored by cc_location() and family, use get_tiles() for custom Mapbox styles. This is part of the decoupling of raster load from tile getting.

• tiles_to_polygon() now returns wk rct vector, not sf.

• Made functions casey(), mawson(), and davis() defunct, because mapbox doesn’t work down there now? (might update with virtualearth)

• Functions cc_location() and friends now return terra SpatRaster. These functions now ignore arguments ‘max_tiles’ and ‘zoom’, but gain a new argument ‘dimension’. If this is not set something resembling the graphics device is used.

o CHANGES

• Removed magrittr.

• New function unpack_rgb() to calculate elevation from packed Byte Mapbox terrain-rgb.

• New function read_tiles() replaces old use of cc_location() to actually read downloaded tiles.

• ceramic no longer imports from spex.

• Objects from {terra}, {stars}, {wk} and {geos} are now supported for using in cc_location(loc = ).

• No custom styles are available now for cc_location, there’s only ‘mapbox.satellite’.

• Removed raster handling support.

• Removed virtual tiles (see hypertidy/grout).

• Begin move to use GDAL for the read, separate tile downloading from raster input.

• Fixed cc_kingston location.

• Removed all references to non-supported mapbox styles, we now have ‘mapbox.satellite’ and and ‘mapbox.terrain-rgb’. Others can be used with a custom styles URL from your own mapbox account.

• Removed unused LazyData in DESCRIPTION.

• Removed dependency rgdal.

• Standardized use of longlat and spherical mercator spec.

• Tweaked behaviour of debug argument, thanks to prompt by Grant Williamson.

• Fix bug in cc_elevation that prevent use of Amazon tiles.

ceramic 0.6.0

• Removed unused data set.

• Added Value elements for several documentation pages.

ceramic 0.5.0

Breaking changes

• Function down_loader() is no longer exported.

• Function slippy_cache() is now deprecated, please use ceramic_cache().

New features

• New focus on tile-downloading versus tile-loading (as a raster object). The function get_tiles() does nothing but download the tiles. The functions cc_location() and cc_elevation() trigger get_tiles() to download if needed, and then merge tiles into the appropriate raster object.

• New function ceramic_cache() to replace deprecated older function.

• Function get_api_key() is now exported.

• In debug mode the files are only printed, not downloaded. In this case the tile object is returned invisibly.

• down_loader() and higher level functions that use it will report on the download task about to occur.

• Function get_tiles() will happily download tiles for any source at any zoom for the entire world.

• Renamed internal get_loc() function to get_tiles().

• Imagery getter functions now accept type = "elevation-tiles-prod" for AWS terrain tiles.

• Function cc_location, cc_elevation and friends now allow loc input to be sf, raster, sp types in any projection.

• Function cc_location and cc_elevation and friends now allow input of either max_tiles or zoom.

ceramic 0.1.0

• Now aligned to slippymath 0.3.0.

• Added function cc_elevation.

• Early dev, with Miles McBain at FOSS4G Oceania 2018!
