SpatiaLite - VirtualShape [version 2.2]

Quick intro

• SQLite is a popular DBMS, simple, robust, easy to use and really lightweight
• each SQLite database is simply a file; you can freely copy it, compress it, send it on a LAN or WEB with no complication at all
  They are also portables; the same database file will work on Windows, Linux, MacOs etc
• the SpatiaLite extension enables SQLite to support spatial data too [aka GEOMETRY], in a way conformant to OpenGis specifications
  • 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, this comprehending sophisticated spatial analysis functions such as Overlaps(), Touches(), Contains() and so on
  • 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
• the GUI tool supports all this, in an user friendly way
