raster-frames changelog

Changelog History

• v0.6.1 Changes

  March 31, 2018

  • ➕ Added support for reading striped GeoTiffs (#64).
  • 🚚 Moved extension methods associated with querying tagged columns to DataFrameMethods for supporting
    temporal and spatial columns on non-RasterFrame DataFrames.
  • GeoTIFF and GeoTrellis DataSources automatically initialize RasterFrames.
  • ➕ Added RasterFrame.toMultibandRaster.
  • ➕ Added utility for rendering multiband tile as RGB composite PNG.
  • ➕ Added RasterFrame.withRFColumnRenamed to lessen boilerplate in maintaining RasterFrame type tag.

• v0.6.0 Changes

  March 18, 2018

  • ⬆️ Upgraded to Spark 2.2.1. Added VersionShims to allow for Spark 2.1.x backwards compatibility.
  • Introduced separate rasterframes-datasource library for hosting sources from which to read RasterFrames.
  • Implemented basic (but sufficient) temporal and spatial filter predicate push-down feature for the GeoTrellis layer datasource.
  • ➕ Added Catalyst expressions specifically for spatial relations, allowing for some polymorphism over JTS types.
  • ➕ Added a GeoTrellis Catalog DataSource for inspecting available layers and associated metadata at a URI
  • ➕ Added GeoTrellis Layer DataSource for reading GeoTrellis layers from any SPI-registered GeoTrellis backend (which includes HDFS, S3, Accumulo, HBase, Cassandra, etc.).
  • Ability to save a RasterFrame as a GeoTrellis layer to any SPI-registered GeoTrellis backends. Multi-column RasterFrames are written as Multiband tiles.
  • ➕ Addd a GeoTiff DataSource for directly loading a (preferably Cloud Optimized) GeoTiff as a RasterFrame, each row containing tiles as they are internally organized.
  • 👍 Fleshed out support for MultibandTile and TileFeature support in datasource.
  • ➕ Added typeclass for specifying merge operations on TileFeature data payload.
  • ➕ Added withTemporalComponent convenince method for creating appending a temporal key column with constant value.
  • 💥 Breaking: Renamed withExtent to withBounds, and now returns a JTS Polygon.
  • ➕ Added EnvelopeEncoder for encoding JTS Envelope type.
  • 🔨 Refactored build into separate core and docs, paving way for pyrasterframes polyglot module.
  • ➕ Added utility extension method withPrefixedColumnNames to DataFrame.
