Announce
1

Hi,

On behalf of the GDAL/OGR development team and community, I am pleased to

announce the release of GDAL/OGR 2.2.0. GDAL/OGR is a C++ geospatial

data access library for raster and vector file formats, databases and

web services. It includes bindings for several languages, and a variety

of command line tools.

http://www.gdal.org/

The 2.2.0 release is a major new feature release with the following

highlights:

  • New GDAL/raster drivers:

  • DERIVED driver: read-support. Expose subdatasets in a a new metadata domain, called DERIVED_SUBDATASETS

  • JP2Lura driver: read/create support for JPEG-2000 images using Luratech JP2 Library

  • PRF: add read-only support for PHOTOMOD PRF file format driver (github #173)

  • RRASTER driver: read-support .grd/.gri files handled by the R ‘raster’ package (#6249)

  • New OGR/vector drivers:

  • CAD driver: read support for DWG R2000 files (GSoC 2016 project)

  • DGNv8 driver: read-write support for DGN 8.0 format (using Teigha ODA libraries)

  • GMLAS driver: read-write support. XML/GML driver driven by Application Schemas.

  • New utility script: ogrmerge.py to merge several vector datasets into a single one

  • New /vsigs/ and /vsigs_streaming/ virtual file systems to read Google Cloud Storage non-public files

  • Significantly improved drivers:

  • NWT_GRD: write support (#6533)

  • FileGDB/OpenFileGDB: add support to read curve geometries (#5890)

  • VRT derived band: add the capability to define pixel functions in Python

  • Add read support for RasterLite2 coverages in SQLite driver

  • GPKG: implement tiled gridded elevation data extension

  • ISIS3: add write support and improve read support

  • RFC 63: Add GDALRasterBand::GetDataCoverageStatus() and implement it in GTiff and VRT drivers

  • RFC 64: Triangle, Polyhedral surface and TIN

==> this RFC introduces potential backward incompatible behaviour.

  • RFC 66: OGR random layer read/write capabilities

  • RFC 67: add null field state for OGR features, in addition to unset fields

https://trac.osgeo.org/gdal/wiki/rfc67_nullfieldvalues

==> this RFC introduces potential backward incompatible behaviour.

Consult MIGRATION_GUIDE.txt

  • Upgrade to EPSG database v9.0 (#6772)

  • Python bindings: Global Interpreter Lock (GIL) released before entering GDAL native code (for all, in GDAL module and a few ones in ogr like ogr.Open())

  • Continued major efforts on sanitization of code base

  • Remove bridge and vb6 bindings (#6640)

  • GNM built by default
