gpkg 0.0.9

  • 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)

    • Checks that gpkg_contents and gpkg_spatial_ref_sys exist
    • Checks that at least one tile or vector dataset (with at least 0 rows) is in the database and gpkg_contents

gpkg 0.0.8

  • Added 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.

    • Found a regression in {terra} behavior that was reported and fixed, so the likelihood of error in the future is lower.

  • 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 0.0.7

  • Added gpkg_bbox() as an application of gpkg_ogr_query()

gpkg 0.0.6

  • 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.

gpkg 0.0.5

  • 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/user/sql_sqlite_dialect.html and https://gdal.org/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.

gpkg 0.0.4

  • 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

gpkg 0.0.3

  • Refactoring table accessor methods (#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()

gpkg 0.0.2

  • 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

    • fixes error with updating contents of GPKG with extensions loaded

  • 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

gpkg 0.0.1

  • Initial draft of key features, R package structure, and naming of functions
