Added auto_nodata argument for gpkg_write() automatic selection of a appropriate NoData value when NoData = NULL
Default NoData values are now set using the new gpkg_default_nodata() function when auto_nodata = TRUE and no explicit NoData value is provided
Added gpkg_default_nodata() to return appropriate default NoData values for supported raster datatypes, following GDAL and terra conventions. This function is documented and exported for user access
destfile argument to gpkg_write() and replaced with y, which now accepts geopackage or DBIConnection objectsMajor cleanup and more consistent use of internal SQLiteConnection usage to ensure open connections don't get garbage collected
Added gpkg_disconnect() convenience methods for tbl_SQLiteConnection and src_SQLiteConnection
Added gpkg_connection() a user-level function for accessing or creating SQLiteConnections given a geopackage object or a path to GeoPackage file
Added [ and [[ methods for accessing/replacing tables in a geopackage object
Replaced vapour functionality for driver detection with gdalraster equivalents
Added gpkg() alias for geopackage()
Added gpkg_create_geometry_columns(), gpkg_geometry_columns() and gpkg_add_geometry_columns()
Added gpkg_sf() convenience method for creating an sf object from tables. Defaults to a sf tbl_df, use as_tibble=FALSE for data.frame.
Now using new gpkg_create_spatial_ref_sys() function internally to ensure GeoPackages have the minimum required tables
gpkg_collect() and gpkg_table(collect=TRUE) gain support for selecting a subset of columns of interest
Deprecate gpkg_create_dummy_features() function name and replace with gpkg_create_empty_features()
Deprecate gpkg_contents(template=) argument, provide new arguments for each data element (SRS ID and bounding box)
Implemented GDAL driver detection for file paths via {vapour} for #15
Implemented functions for creating gpkg_spatial_ref_sys table and adding or removing spatial reference system records:
gpkg_create_spatial_ref_sys(), gpkg_add_spatial_ref_sys() gpkg_delete_spatial_ref_sys(), gpkg_list_srs()Implemented basic gpkg_validate() routine (will be expanded)
gpkg_contents and gpkg_spatial_ref_sys existgpkg_contentsAdded gpkg_create_spatial_view() for creating spatial views, which are dynamic layers accessible as if they were typical static geometry layers (for #6).
gpkg_write() now properly writing attributes from a data.frame source (which is not nested in a list) when table_name argument is
gpkg_tables() better handling for terra::vect() failures with non-spatial table function fallback.
gpkg_write() now can handle SpatVectorProxy input by querying it. Note this will not work for data that will not fit in memory. May try to implement an ogr2ogr-like interface for this in the future (#15).
gpkg_bbox() as an application of gpkg_ogr_query()geopackage() internal connection object has been moved to an internal environment (<geopackage>$env$con rather than <geopackage>$con)
gpkg_connect() allows for in-place modification of an existing object for the purposes of creating an internal SQLiteConnection
Improvement to gpkg_add_contents() and gpkg_update_contents(): more intelligent choice of data type when heterogeneous (non-attribute) data are in database but not registered. Fix for broken tests on Windows/GDAL 3.5.2.
Fixed bug in gpkg_tables() when multiple attribute tables were present.
Added gpkg_ogr_query() (and ogr argument to gpkg_query()) to support querying OGR data sources using a 'terra' SpatVectorProxy back end. This allows for use of GeoPackage-specific SQL functions and the OGR/SQLite dialects: https://gdal.org/en/stable/user/sql_sqlite_dialect.html and https://gdal.org/en/stable/user/ogr_sql_dialect.html; requires latest 'terra' (1.7-33+)
Added gpkg_rast() (analog of gpkg_vect() for terra::rast()) for lazy manipulation of gridded data in a GeoPackage
Added gpkg_create_dummy_features() which is a workaround for use of gpkg_vect() on a GeoPackage with only attribute data. This creates innocuous entries in gpkg_geometry_columns and an empty table to "trick" GDAL into reading arbitrary data sources.
Added gpkg_list_contents() and gpkg_ogr_contents(); the former returns only table names registered in gpkg_contents table, which are optionally intersected with tables defined in gpkg_ogr_contents when ogr=TRUE.
Fixed bug in .gpkg_gdaloptions_add() that could cause addition of options with no value set
Added gpkg_vect(): a terra::vect()-based analog of gpkg_table() for lazy manipulation of vector and attribute data in a GeoPackage
gpkg_update_table() defaults to wherecol=NULL which allows updating rows with no SQL WHERE clause specified
Refactoring table accessor methods (https://github.com/brownag/gpkg/issues/2)
Renamed lazy.frame() -> gpkg_table_pragma()
Renamed dplyr.frame() -> gpkg_table()
gpkg_table() gains collect argument (toggles materializing data.frame v.s. 'dbplyr' approach). collect requires only 'RSQLite' not 'dbplyr'.
gpkg_tables() gains pragma argument to toggle use of gpkg_table_pragma() over gpkg_table(). It also supports collect argument.
gpkg_update_table() is now exported; this method is/was used internally for updating the NoData entry for existing layers via gpkg_tile_set_data_null()
Updated definitions of lazy.frame() and dplyr.frame() and related docs
Updated gpkg_write() for raster, vector, and attribute data
General cleanup and refactored approach for splitting input data sources between attributes, vector, and tiled grid coverage.
New approach still contains hard-coded logic related to the allowed object types and file data sources (that will be generalized in the future)
RASTER_TABLE name is now properly injected into GDAL options from named list input (when not otherwise specified)
Bug fix in geopackage(<list>) related to appending v.s. overwriting raster data
gpkg_update_contents(): Handle gpkgext_ and sqlite_sequence as standard GPKG table prefixes
Added {dbplyr} backend option to return tibble object via geopackage object internal SQLiteConnection
Changed formatting of PRAGMA table_info child data.frame in lazy.frame() result
