Fixed leaks from valgrind, thanks CRAN and rhub.
Cleaned up a number of address sanitize issues and segfaults, thanks to CRAN.
Old warper code is removed, now uses 'gdal_raster_' from warpgeneral.
Fixed putting bad options in (empty strings).
Fixed type problem in internal get projection strings.
Urgent release to fix segfault on CRAN, instances of int instead of IntegerVector for R devel.
Fix incorrect format string for "-te".
Use pkg-config on Windows when available, thanks Tomas Kalibera and CRAN.
New function gdal_raster_nara() to return nativeRaster in a list understood by ximage().
New function vector_vrt() to generate VRT for SQL and/or reprojection.
Fix cross-compilation for ARM on universe, thanks to Jeroen Ooms.
New function buildvrt() as a special-case for -separate from gdalbuildvrt app.
vapour_vrt() gains 'options' argument, so we can in particular do options = c("-expand", "rgb", "-ot", "Byte") to warp
16-bit integer colour palettes from GTiff to PNG. :)
gdal_raster_dsn() can now write to non-GTiff/COG via options = c("-of", DRIVER).
New function vapour_geolocation() retrieves any existing geolocation information.
vapour_vrt() called with geolocation arrays now scrubs the geotransform from the output (which ensures the
warper uses the arrays without setting '-geoloc').
vapour_create() gets creation options, data type options, and driver options.
Fixed failure to close file created by vapour_create() fixes #202.
vapour_vrt() gains an 'overview' argument. Wish of https://github.com/hypertidy/vapour/issues/186
gdal_raster_data(), gdal_raster_dsn(), and gdal_raster_image() now allow a source with geolocation arrays to be warped to a non-longlat projection.
The extent reported by 'vapour_raster_info()' is now correct for the general case including non-zero skew geotransforms.
'vapour_raster_info()' gains a 'corners' element.
All functions that read or query data source/s now check for tilde "~" at the beginning of the string/s, and normalize the path as needed. Reported by @Sibada in #193.
vapour now imports nanoarrow and includes internal experimental support for GDAL (>= 3.6) stream reading (RFC 86). Nothing is exposed for general use yet.
New Makevars.ucrt with patch contributed by CRAN, Tomas Kalibera.
raster read gains "unscale" argument, TRUE by default which means offset and scale values are applied and return value is of type Float64, set to FALSE to avoid applying scale/offset to band values (this was always implicitly false (no offset scale applied) if the output type wasn't suitable). .
Fix inefficiency in gdal_raster_data() which was warping all bands in MEM lol.
Fix for vapour_vrt() where 'geolocation' was not being included. Fixes #192.
New capability to drop dataset and band metadata, used by functions vapour_vrt() and vapour_warp_raster() which gain a new argument 'nomd', which
is FALSE by default. If TRUE, the dataset and band metadata are removed from an open dataset before it is converted to VRT.
This particularly makes VRT DSN strings a lot smaller, for use by whatarelief and raadtools for example. There should be no change to current default uses, the argument 'nomd' must be specified for the change.
New function vapour_crs_is_lonlat() to test crs string.
Removed C++11 requirement.
remove LDFLAGS from configure, as per sf #1369 and vapour #188, thanks to @gremms1 and @sgoslee for report on Fedora.
Removed FromHandle (introduced GDAL 2.3) and undeclared use of down_cast, and now tested on GDAL 2.2.3.
New Makevars.ucrt with patch contributed by CRAN, and removed outdated C++11 requirement.
Resubmit after 0.9.1 was rejected, fixed configure.ac and checked on on M1MAC/macbuilder.
The SQL dialect in use for the 'sql' argument can now be controlled, it is set to "" by default. See ?vapour-package for details.
'vapour_layer_info' now supports spatial filter, the 'extent' argument in 'vapour_layer_info' is now for limiting the spatial extent of a layer query (was for controlling whether extent calculated or not).
'gdal_read_names' removed from gdallibrary, and 'read_names_gdal_cpp' renamed to 'read_fids_gdal_cpp' and now returns a numeric vector rather than a list.
Fixed another stray cast (int), now checking more robustly for nodata value for integer bands. We have made some inroads into better consistency of use of long integer values in the code base, but vapour does not yet support long vectors.
Big cleanup.
Resubmit after 0.8.82 was rejected.
Fix examples and documentation for 'sst_c', 'vapour_read_geometry', 'vapour_read_fields', 'vapour_create()', 'vapour_read_raster_block()' and 'vapour_write_raster_block()' from CRAN submission.
Clarified authorship for Jim Hester (listed as copyright holder in DESCRIPTION), removed comment from code in CollectorList.h.
Resubmit after 0.8.8.81 was removed.
Remove obscure NetCDF/HDF5 tests that don't work on CRAN macos.
'vapour_sds_names()' now returns a character vector not a list.
'gdalraster::gdal_list_subdatasets' now returns unprocessed subdataset strings, of the form 'SUBDATASET_{i}_NAME={DRIVER}:{URI}:layer', and the strings are cleaned in R (but, can use vapour_raster_info, vapour_sds_names() for a separate pathway to this.)
Fixed CRAN warnings due to incorrect use of boolean operator, #158.
vapour_raster_info() gains a subdatasets vector, this is just the source input if subdatasets are not present.
Subdatasets can now be named by variable name or by index in 'vapour_vrt()'. Note this can't always work as some services don't have names in the sense that classic subdataset sources (like netcdf) do.
'warp_options' and 'transformation_options' has been removed from the 'gdalwarpmem' namespace, and from the R and Rcpp wrappers. All options are now assumed to be bundled into one string list (CharacterVector).
Setting options for the 'vapour_warp_raster()' has been reconfigured. Arguments 'warp_options', 'transformation_options', 'open_options', and 'dataset_output_options' correspond to the 'NAME=VALUE' configuration provided by gdalwarp as '-wo', '-to', '-oo', and '-doo'. All of these should be entered in bare form (without the '-wo', '-to' etc) but for 'options' these must be entered as per standard gdalwarp options. Some are disallowed and are checked for, triggering an error because we either set them via other arguments, or they can't be supported atm.
New options setting support means we can support all gdalwarp options, notably '-cutline', '-csql', '-cwhere', and '-crop_to_cutline' which allow masking by a a polygon layer from a vector data source. Thanks to Hugh Graham for the motivation for this. :)
New internal function raster_has_geolocation_gdal_cpp(), early begin of does
this datasource have geolocation arrays (because if it does we can just push it
through the warper, otherwise nominate them with vapour_vrt(geolocation = )).
vapour_vrt() gains geolocation argument, which can be named dsns for each of
longitude,latitude. Currently assumed to be 'OGC:CRS84'.
Now depend on GDAL 2.2.3 as a minimum, because ubuntu 18.04 is still in wide use. GDALInfo() lib needs GDAL 2.1 as minimum. Some info features need later, but do not fail (AFAIK).
vapour_raster_info() now has dimension element, intended for use instead
of dimXY (for standard idiom like {gdalio} uses with 'extent', 'dimension',
'projection' as the basis of what a raster is). dimXY will be removed in
future.
New namespace 'gdalapplib' with one utility for GDALInfo(), this is vectorized
at the cpp level and includes subdataset handling. It does not include listing
of TAR and ZIP archives. vapour_raster_info() now uses this.
New functions vapour_create() vapour_read_raster_block() and
vapour_read_raster_block() for creating and writing to files.
Moved C++ functions gdal_sds_list(), gdal_extent_only()
gdal_raster_info(), gdal_raster_gcp(), init_resample_alg(),
gdal_read_band_values(), gdal_read_dataset_values(),
gdal_raster_dataset_io(), gdal_raster_io() to gdalraster namespace from
gdallibrary namespace. (Some of these will get refactored out).
New function vapour_vrt().
vapour_warp_raster() default has changed for bands, it's now NULL which
means "all bands", not 1L.
New functions vapour_set_config() and vapour_get_config() to control configuration
options for GDAL.
Flushed out memory bugs with valgrind.
Refactored read from raster and warp raster. The warping uses the same band reader as the RasterIO reader, and more cases of 'GDALOpen()' for rasters go via the underlying 'gdalraster' namespace pathway.
Faster layer extent determination in vapour_layer_info(), new function vapour_layer_extent().
Better escaping for layer name, needed quotes around layer 'SELECT' when counting features with SQL for FlatGeoBuf.
(This never made it to CRAN.)
Patch release for R UCRT changes. Applied patch provided by CRAN.
Removed invalid missing value setting for type raw and int in the warper, causing representable range errors on cran.
Raster read now detects type of the source and return raw, integer, or double as per the native type in the source.
wkt argument for the target projection in warper functions is now replaced
by 'projection'. If 'wkt' is given it is used to set the value for 'projection'
and a message emitted. No change has been made at the C++ level, which still uses the
original names.
Fixed configure.ac, upgraded syntax causing warnings on CRAN.
Fixed huge SDS name wrecking bug. So now works for WMTS sources, for example.
Fixed bug in use of scaling, was applied without conversion to floating point type.
vapour_raster_info() gains datatype field.
Warp read functions gain warp_options and transformation_options.
New feature to provide band_output_type to raster read functions, to take
Byte, Int32, or Float64.
New functions vapour_read_raster_raw(), vapour_read_raster_int(),
vapour_read_raster_dbl(), vapour_read_raster_chr() and its alias
vapour_read_raster_hex() to return specific types of atomic vector. _chr and
_hex convert raw bytes to colours.
New function vapour_read_raster_block() a helper around the internal C++
reader for the simple case of offset/dimension read. There's a matching but
non-exported vapour_write_raster_block(). See issue/PR #123 for examples.
Remove unused vapour.cpp which trigger unused warnings: MAX_INT variable and code GetPointsInternal, warnings on CRAN r-devel-linux-x86_64-fedora-clang, 2021-08-03.
Fixed dependence on GDAL, require version GDAL >= 2.3.0. Older versions not const correct for OGRGeometry::importFromWkt(), triggering errors on Solaris CRAN which was GDAL 2.2.4 at 2021-08-03.
Fixed vapour_layer_info(), now accepts name of layer not just index to be more consistent across other layer functions. Now includes
more information about the layer.
vapour_read_fields() will now return binary fields.
vapour_srs_wkt() now accepts more inputs, not just proj strings.
Include OFTBinary in supported field types.
REALLY fixed the CRAN UBSAN problem. Listed here: https://github.com/hypertidy/vapour/issues/110
vapour_raster_info() gains 'extent' element.
vapour_report_fields() new function aliased to vapour_report_attributes() and vapour_read_fields() to vapour_read_attributes() as more sensible names for what they do. The '_attributes' versions might be deprecated in future.
vapour_layer_info() gains driver, layer name/s, fields, and feature count.
vapour_raster_info() now returns $projstring, the proj string version of $projection (was called 'proj4' and previously
unimplemented). The value may be an empty string.
File list from vapour_raster_info() now returns a missing value (NA) when no files are in the list.
Fixed a serious bug caused by 'vapour_raster_info()' attempting to create a character vector from a null pointer when no file list exists for a source (such as an image server).
Fixed input type problems found on CRAN, see https://github.com/hypertidy/vapour/issues/110. Thanks to CRAN for explaining.
Warper input can now include multiple sources.
Fixed CRAN windows problem with NetCDF.
New internal functions vapour_read_geometry_ia() and vapour_read_geometry_ij() to read by feature id arbitrary
and range - not sure if will make export ... _fa() counterpart is problematic.
New function vapour_layer_info() to return the previous internal projection string info for a vector
layer.
Fix to configure for Fedora thanks to Inaki Ucar (@Enchufa2) https://github.com/hypertidy/vapour/issues/95
vapour_warp_raster() now accepts an extent for the extraction with giving a dimension, it returns native
pixels found within that extent. This is a special case for when you have control over the input window extent
and now the dimensions implicitly. (We might formalize around storing the dimensions, extent, and crs as an
attribute but that's been unnecessary so far.)
Input projection strings for wkt or source_wkt in vapour_warp_raster may be anything acceptable by GDAL itself. These
include WKT variants, PROJ strings, EPSG strings, and file names.
The function vapour_warp_raster() now uses argument 'bands' rather than 'band' at the R level. The warper function
correctly handles repeated band numbers in bands and can be set to NULL, to return all bands. (Note that vapour_read_raster()
still uses 'band').
User interface for `vapour_warp_raster()' now changed to use 'extent' and 'source_extent' in place of 'geotransform' and 'source_geotransform', which are now deprecated.
Function vapour_warp_raster() now exported, properly handles input-replacement geotransform or projection
for sources that have insufficient metadata. This works with a variety of input data source names (files, URLs,
image servers, etc.) Overviews are automatically dealt with (by choosing the right level of detail) by using
the gdalwarp app library functionality. (This warp function may be refactored to use extent rather than geotransform).
Added vsi example with zipped shapefile.
Fixed missing stdlib.h declaration for exit() in configure tests, thanks to CRAN. #88
New function vapour_read_type() to return the integer geometry type (GDAL's
wkb enum code).
vapour_read_geometry(what = "point") is now defunct
Major refactor to use C++ headers, so other packages can access the API without using R functions. There's a more comprehensive set of identifier, names, fields, extent, and geometry readers, and an addition of the GDALwarp() facility which is a generalization of RasterIO. This will now work on a much greater range of sources than the older RasterIO (still WIP).
New function vapour_geom_name() to get a data source geometry "column name".
Non-database sources return an empty string unless ExecuteSQL() was called,
and then it is "ogr_geometry".
Typical names are 'geom' in GPKG, 'SHAPE' in GDB.
Deleted compile tests from configure, we can add proper tests if this is needed.
Now set env vars GDAL_DATA and PROJ_LIB to vapour/gdal/ and vapour/proj/ when present (i.e. Windows generally, MacOS on CRAN).
Update to configure to ensure data copy of proj/ and gdal/ on MacOS on CRAN, thanks to CRAN, Roger Bivand, and to James Balamuta for enormous help on github actions and installing the CRAN mac binaries.
Now using GDAL 3 on Windows.
Get available overview sizes, wish of #78.
Improve tests to be more robust, thanks to CRAN. #77
Removed pesky message and failing tests thanks to Joseph Stachelek (@jsta) #76.
vapour_read_raster() now returns a list of (one) numeric vector. This change
is so a future version can return more than one band for this and related functions.New data set tas_wkt a Well-Known-Text string to simplify an example
in the documentation.
The function vapour_read_raster() now returns a list with a single vector of
values from the requested band. In future this may return values from multiple
bands. The new function vapour_warp_raster() uses the same scheme.
Fixed static linking for MacOS build, thanks(!!) to Jeroen Ooms for guidance and thanks to CRAN for reporting the issue.
New function vapour_srs_wkt() to convert PROJ4 strings to Well-Known Text.
New internal-only function vapour_warp_raster() to return a warped version from
a raster source. Please use with caution, it's still flaky for certain cases and will
crash your session (setting projection on NetCDF 0,360 is one example but not fleshed
out yet - see hypertidy/lazyraster for in-dev usage examples.)
New internal function warp_memory_cpp() to warp small in memory rasters.
Updates to configure to remove deprecated R CMD config CPP (thanks to CRAN).
Updates to enable use of the deprecated PROJ API.
New function vapour_vsi_list() to list contents of virtual files. See https://twitter.com/mdsumner/status/1158335706483179521 and https://github.com/hypertidy/vapour/issues/55 for inspirations.
Added a hex sticker! Thanks to @Maschette.
Added 'proj4' string as well as 'projection' (WKT) to the output of vapour_raster_info()
(these aren't always available, especially not for longlat NetCDF).
Fixed failure in limit_n, skip_n behaviour for reading names (FIDs) and attributes,
(#60).
Fixed incorrect use of C-level printf() and unnecessary tests thanks to CRAN
feedback.
Add 'type' to output of vapour_geom_summary(), the integer code for each
geometry type.
Restructured conversion to text geometries to properly free up memory, was causing memory leaks (found with valgrind).
Use of sql now correctly uses 'GDALDataset::ReleaseResultsSet()' in each
applicable function. Query with the 'sql' argument was not being executed in
vapour_layer_names() but now is - only has utility for insert and drop queries,
so will be rarely used and probably never had any impact before.
Raster read gains a new argument native = FALSE to control use of the native
window without specifying it. If native = TRUE then the native dimensions
are used and read in full.
Vector read functions gain new extent argument to apply a spatial filter in
conjunction with the sql argument, per discussion (#34). The extent can be of
type sp, sf, raster, or generic vector c(xmin, xmax, ymin, ymax). The extent
is ignored if the sql argument is not specified, with a warning. Applies to
vapour_geom_summary(), vapour_read_attributes(), vapour_read_extent(),
vapour_read_geometry(), vapour_read_geometry_text(), and vapour_read_names().
Thanks to Joseph Stachelek for the suggestion.
Vector read functions gain new limit_n and skip_n arguments to specify a
sequential set of features to be read, added to vapour_geom_summary(),
vapour_read_attributes(), vapour_read_extent(), vapour_read_geometry(),
vapour_read_geometry_text(), and vapour_read_names(). Their effect occurs
after that of the sql argument.
New function vapour_driver() to determine chosen driver (vector, short name)
of the data source.
New argument min_max to allow fast default use of vapour_raster_info(), as
per (#50).
New function vapour_raster_gcp() to return GCP (ground control points) if
present.
New function vapour_report_attributes() to return a string description of
the internal GDAL type for data attributes wish of Grant Williamson.
Attribute types 'OFTInteger64' are now returned as doubles, 'Date' and 'DateTime' are returned as strings.
New functions vapour_gdal_version() and vapour_all_drivers() to return
information about the GDAL library in use.
Function vapour_read_names() is now implemented using the library API, rather
than via OGRSQL. All trace of the OGRSQL FID workaround and warning has been
removed.
New function vapour_geom_summary() to return basic identity, validity, and
extent of feature geometries.
Values for the extent (bounding box) of a feature are now set to NA values for an empty or missing geometry.
Fix drastic memory leak in vapour_read_attributes(), thanks to Grant Williamson.
Functions that include a layer index now accept a layer name which is used to find the (0-based) layer index.
This is a breaking release, all old functions have been made defunct or removed entirely.
All C++ functions now have explicit R wrappers instead of Rcpp exports.
New naming convention uses vapour_ for vector sources, raster_ for raster sources
to make function names a little more consistent.
New wrapper vapour_sds_names to replace sds_info and raster_sds_info which are now deprecated.
New wrapper vapour_read_geometry_what to replace vapour_read_feature_what which i is now deprecated.
New function vapour_read_names to return the vector of FID values.
The read for raster data now returns numeric or integer appropriately.
vapour_raster_info now includes bands as the count of available bands.
The IO read now allows a 4-element window to return data at native resolution, by
copying the third and fourth values (source dimension) to the fifth and sixth values
(output dimension) respectively.
Subdatasets are now supported.
Added sanity check behaviour to vapour_raster_read to avoid out of bounds read attempts.
Resampling options added to raster data read.
Upgraded to rwinlib gdal 2.2.3.
added function vapour_layer_names to return character layer names, and
implicitly provide a layer count
feature iteration now avoids "GetFeatureCount" and collects each element in a growing list, thanks to Jim Hester
renamed format argument to textformat, this is ignored unless what = "text"
Created a single C++ feature read to remove repeated logic, vapour_read_geometry, vapour_read_geometry_text, and vapour_read_extent all call the same function.
