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.
