Arguments

x: A geopackage object
column_name: Default: "srs_id"
default: logical or character. If TRUE, or one or more of "cartesian", "geographic", or "crs84", then these default Spatial Reference Systems are added.
query_string: logical. Return SQL queries without executing? Default: FALSE
srs_name: character. Spatial Reference System Name, for example "WGS 84 geodetic"
srs_id: integer. Spatial Reference System ID, for example 4326L
organization: character. Organization, for example "EPSG"
organization_coordsys_id: integer. Organization Coordinate System ID, for example 4326L
definition: character. WKT2019 Coordinate Reference System description string
description: character. Description

Value

gpkg_spatial_ref_sys(): data.frame

gpkg_list_srs(): vector of values from specified column_name

gpkg_create_spatial_ref_sys(): integer. Result of running sequential gpkg_execute() statements. This method is run for the side-effect of creating the table if needed, and adding any "default" records.

gpkg_add_spatial_ref_sys(): integer result of executing SQL statement

gpkg_delete_spatial_ref_sys(): integer result of executing SQL statement
