./geography/gdal-lib, Translator library for raster geospatial data formats

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 2.2.4nb4, Package name: gdal-lib-2.2.4nb4, Maintainer: brook

GDAL is a translator library for raster geospatial data formats that
is released under an X/MIT style Open Source license. As a library, it
presents a single abstract data model to the calling application for
all supported formats. The related OGR library (which lives within
the GDAL source tree) provides a similar capability for simple
features vector data. It includes roughly 60 format drivers. Current
translators include:
* GeoTIFF (read/write)
* Erdas Imagine (read/write)
* ESRI .BIL (read)
* .aux labelled raw (read/write)
* DTED (read)
* SDTS DEM (read)
* CEOS (read)
* JPEG (read/write)
* PNG (read/write)
* Geosoft GXF (read)
* Arc/Info Binary Grid (read)
A full list is available at http://www.gdal.org/formats_list.html.

with VRT for example

SXF driver:
 * fix wrong use of endianness macros to fix behaviour on big-endian hots
 * add recoding from CP1251 for TEXT attribute that is now decoded
 * fix various issues (#6357)

VRT driver:
 * implement CloseDependentDatasets()
 * fix editing with 'direct' geometry mode which could cause attribute column to \ 
be empty (#6289)
 * fix crash with a OGRVRTWarpedLayer using a source layer that would have non \ 
geometry column (unlikely to happen currently as this would require explicit \ 
disabling it, but more likey with following commit that createe VRT non-spatial \ 
layer implictly when the source is non-spatial, linked to #6336)
 * avoid creating an implicit wkbUnknown geometry field when the source has no \ 
geometry column and there's no XML elements related to geometry fields (#6336)

XLSX driver:
 * fix reading sheets with more than > 26 columns and 'holes' (#6363)

XPlane driver:
 * extend ICAO identifiers to 5 digits (#6003)

== SWIG Language Bindings ==

All bindings:
 * add a options parameter to gdal.ReprojectImage() to pass warp options
 * Change ReadRaster and WriteRaster to use GIntBig and the *IOEx-methods
 * prevent NULL file pointer from being passed to VSIF*L functions
 * make gdal.Rename() accept Unicode strings
 * add SpatialReference.GetAxisName() and SpatialReference.GetAxisOrientation() \ 
 * add SpatialReference.GetAngularUnitsName() (#6445)

Java bindings:
 * Fix typemap for input parameter of type GIntBig (fixes GetFeature(long), \ 
DeleteFeature(long), etc...) (#6464)
 * Bump minimal java version to 1.5 in case SWIG generates anotations (#6433, \ 
patch by Bas Couwenberg)
 * GNUmakefile: add -f in rm commands
 * GNUmakefile: add support for all hardening buildflags

Perl bindings:
 * Fix #6050: string formatting in croak.
 * Perl Makefile.PL: add support for all hardening buildflags (#5998)
 * use strict and warnings in overridden constructors.
 * add $VERSION to ogr_perl.i (OGR.pm), which is required by pause.perl.org.
 * Add some basic module info for CPAN.
 * Bugfix for Geo::OGR::Feature->new().
 * Add many utility level algorithms as methods to various classes.
 * New class for XML stuff
 * New Makefile.PL, which can download and build GDAL. This allows automatic \ 
testing of the CPAN module.
 * Wrap VSIStdoutSetRedirection and allow creating datasets via an object, which \ 
can write and close.
 * Geo::OGR::Driver and Geo::OGR::DataSource are now Perl wrappers for \ 
respective GDAL classes.
 * Add to the error stack also errors from the bindings
 * Fix sending utf8 from Perl to GDAL. Should also remove some \ 
"uninitialized value" warnings.
 * ReadTile and WriteTile methods for Dataset, ReadTile accepts now tile size \ 
and scaling algorithm.
 * Improved Parent - Child management.
 * Improved support for 64bit ints.
 * Measures support in Geometry class.
 * Many new tests

Python bindings:
 * make Feature.ExportToJson() output boolean value for a boolean field
 * support floating point coordinates for the source windows of \ 
Band.ReadRaster() and Band.ReadAsArray()
 * fix build with SWIG 3.0.6 (#6045)
 * make gdal.OpenEx() throw a Python exception in case of failed open when \ 
exceptions are enables with gdal.UseExceptions() (#6075)
 * Disable opening a NumPy dataset with a filename returned by \ 
gdal_array.GetArrayFilename(() unless GDAL_ARRAY_OPEN_BY_FILENAME is set to TRUE
 * disable the warning about using deprecated wkb25DBit constant as it uses a \ 
trick that prevents the bindings from being used by py2exe / pyinstaller (#6364)
