GDAL algorithms

  • GDALCreateReprojectionTransformerEx(): do not emit error if reverse transformation fails, and fix crash when trying to use null reverse transformation
  • Warper: fix GDAL 2.3 regression in a situation with source nodata value, multiple bands and nearest resampling where the logic to detect which source pixels are nodata was inverted (#1656)
  • Contour generator: fix SegmentMerger list iterator skipping and out of bounds error. (#1670)
  • Rasterize: fix crash when working buffer is larger than 2GB (fix also gvBurnPoint) (#1338)

GDAL core

  • GDALInvGeoTransform(): make it work with scale and rotation/skew coefficients of small absolute value (#1615)
  • GDALCopyWholeRasterGetSwathSize(): fix potential int overflows for big values of GDAL_SWATH_SIZE or GDAL_CACHEMAX
  • PAM: preserve existing metadata when setting new one (#1430)

GDAL utliities

  • Fixed NaN-streaking in output images when the --allBands option is given to tiled images, and removed redundant calculation of nXValid.
  • fix outputing to geojson without explicit -f switch (#1533)
  • gdal_contour: remove explicit width/precision=12/3 of the elev field (#1487)

GDAL drivers

VRT driver:

  • Python pixel functions: also probe (#1660)

WMS driver:

XYZ driver:

  • fix regression regarding header lines that are not X,Y,Z (#1472)

OGR core

  • segmentize(): fix 2.4.1 regression when 2 points are really close compared to the segmentizatin distance (#1414). Also handle the M dimension
  • RawDataset: use generic RasterIO() implementation when non-nearest resampling is asked (#1301)

OGR utilities

  • add shared='1' to speed-up -single mode with many layers

OGR drivers

EEDA driver:

GeoJSON driver:

  • fix recognizing some documents with members sorted alphabetically (#1537)
  • avoid SetFeature() to repeat first feature when looping over features (#1687)

GeoJSONSeq driver:

GML driver:
