pyogrio 0.4.0

Version 0.4.0

on Python PyPI

Major enhancements

• support for reading from file-like objects and in-memory buffers (#25)
• index of GeoDataFrame created by read_dataframe can now optionally be set
  to the FID of the features that are read, as int64 dtype. Note that some
  drivers start FID numbering at 0 whereas others start numbering at 1.
• generalize check for VSI files from /vsizip to /vsi (#29)
• add dtype for each field to read_info (#30)
• support writing empty GeoDataFrames (#38)
• support URI schemes (zip://, s3://) (#43)
• add keyword to promote mixed singular/multi geometry column to multi geometry type (#56)
• Python wheels built for Windows, MacOS (x86_64), and Linux (x86_64) (#49, #55, #57, #61, #63)
• automatically prefix zip files with URI scheme (#68)
• support use of a sql statement in read_dataframe (#70)
• correctly write geometry type for layer when dataset has multiple geometry types (#82)
• support reading bool, int16, float32 into correct dtypes (#83)
• add geometry_type to write_dataframe to set geometry type for layer (#85)
• Use certifi to set GDAL_CURL_CA_BUNDLE / PROJ_CURL_CA_BUNDLE defaults (#97)
• automatically detect driver for .geojson, .geojsonl and .geojsons files (#101)
• read DateTime fields with millisecond accuracy (#111)
• support writing object columns with np.nan values (#118)
• add support to write object columns that contain types different than string (#125)
• support writing datetime columns (#120)
• support for writing missing (null) geometries (#59)

Breaking changes

• read now also returns an optional FIDs ndarray in addition to meta,
  geometries, and fields; this is the 2nd item in the returned tuple.

Potentially breaking changes

• Consolidated error handling to better use GDAL error messages and specific
  exception classes (#39). Note that this is a breaking change only if you are
  relying on specific error classes to be emitted.
• by default, writing GeoDataFrames with mixed singular and multi geometry
  types will automatically promote to the multi type if the driver does not
  support mixed geometry types (e.g., FGB, though it can write mixed geometry
  types if geometry_type is set to "Unknown")
• the geometry type of datasets with multiple geometry types will be set to
  "Unknown" unless overridden using geometry_type. Note:
  "Unknown" may be ignored by some drivers (e.g., shapefile)

Bug fixes

• use dtype object instead of numpy.object to eliminate deprecation warnings (#34)
• raise error if layer cannot be opened (#35)
• fix passing gdal creation parameters in write_dataframe (#62)
• fix passing kwargs to GDAL in write_dataframe (#67)
