has_spatialite: Is SpatiaLite available?

Description

has_spatialite() returns a logical value indicating whether GDAL was built with support for the SpatiaLite library. SpatiaLite extends the SQLite core to support full Spatial SQL capabilities.

Usage

has_spatialite()

Value

Logical scalar. TRUE if SpatiaLite is available to GDAL.

Details

GDAL supports executing SQL statements against a datasource. For most file formats (e.g. Shapefiles, GeoJSON, FlatGeobuf files), the built-in OGR SQL dialect will be used by default. It is also possible to request the alternate "SQLite" dialect, which will use the SQLite engine to evaluate commands on GDAL datasets. This assumes that GDAL is built with support for SQLite, and preferably with Spatialite support too to benefit from spatial functions.
