[OSGeo-Announce] GDAL 2.2.0 is released

[Jorge Sanz]

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

https://trac.osgeo.org/gdal/wiki/rfc63_sparse_datasets_improvements

* RFC 64: Triangle, Polyhedral surface and TIN

https://trac.osgeo.org/gdal/wiki/rfc64_triangle_polyhedralsurface_tin

==> this RFC introduces potential backward incompatible behaviour.

Consult MIGRATION_GUIDE.txt

* RFC 66: OGR random layer read/write capabilities

https://trac.osgeo.org/gdal/wiki/rfc66_randomlayerreadwrite

* 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
