lazysf: Delayed Read for 'GDAL' Vector Data Sources

Lazy read for drawings. A 'dplyr' back end for data sources supported by 'GDAL' vector drivers, that allows working with local or remote sources as if they are in-memory data frames. Basic features work with any drawing format ('GDAL vector data source') supported by the 'gdalraster' package.

Package Options

There is a debug option options(lazysf.query.debug = TRUE) which if set will cause the generated SQL statement to be printed before every call. In addition it will print the number of rows actually read.

Default geometry format can be set with options(lazysf.geom_format = "WKB"). Default SQL dialect can be set with options(lazysf.dialect = "SQLITE").
