# the SpatiaLite extension enables SQLite to support spatial data too aka GEOMETRY, in a way conformant to OpenGis specifications
# Available at: [L1 ]
- supports standard WKT and WKB formats
- implements SQL spatial functions such as AsText(), GeomFromText(), Area(), PointN() and alike
- the complete set of OpenGis functions is supported via GEOS, thus comprehending sophisticated spatial analysis functions such as Overlaps(), Touches(), Union(), Buffer() ..
- supports full Spatial metadata along the OpenGis specifications
- supports importing and exporting from / to shapefiles
- supports coordinate reprojection via PROJ.4 and EPSG geodetic parameters dataset
- supports locale charsets via GNU libiconv
- implements a true Spatial Index based on the SQLite's RTree extension
# the VirtualShape extension enables SQLite to access shapefiles as VIRTUAL TABLEs
- you can then perform standard SQL queries on external shapefiles, with no need for importing or converting them
# the VirtualText extension enables SQLite to access CSV/TxtTab files as VIRTUAL TABLEs
- you can then perform standard SQL queries on external CSV/TxtTab files, with no need for importing or converting them

JMN 2009-11-07 Looks interesting - but I see no reference to Tcl on the site. I'm assuming by 'extension' this refers only to it being an extension to SQLite, and that there is no Tcl interface?
