New features:

  • Support for CUDA GPU dataframes (cudf and dask_cudf) (#794, #793, #821, #841, #842)

@jbednar jbednar released this Oct 8, 2019 · 44 commits to master since this release

This release includes major contributions from @jonmmease (quadmesh and filled-area support), @brendancol (geospatial toolbox, tile previewer), @philippjfr (distributed regridding, dask performance), and @jsignell (examples, maintenance, website).

New features:

  • Native quadmesh (canvas.quadmesh()) support (for rectilinear and curvilinear grids -- 3X faster than approximating with a trimesh; #779)
  • Filled area (canvas.area()) support (#734)
  • Expanded geospatial toolbox, with support for:
    • Zonal statistics (#782)
    • Calculating viewshed (#781)
    • Calculating proximity (Euclidean and other distance metrics, #772)
  • Distributed raster regridding with Dask (#762)
  • Improved dask performance (#798, #801)
  • tile_previewer utility function (simple Bokeh-based plotting of local tile sources for debugging; #761)

Bugfixes and compatibility:

  • Compatibility with latest Numba, Intake, Pandas, and Xarray (#763, #768, #791)
  • Improved datetime support (#803)
  • Simplified docs (now built on Travis, and no longer requiring GeoViews) and examples (now on examples.pyviz.org)
  • Skip rendering of empty tiles (#760)
  • Improved performance for point, area, and line glyphs (#780)
  • InteractiveImage and Pipeline are now deprecated; removed from examples (#751)
