Tcl扩展阅读和显示各种栅格/矢量空间数据格式。

This GSoC 2009 project attempts to extend Tcl support for GIS applications in general. In particular it introduces Tcl bindings to GDAL/OGR libraries, that allow access to many different raster and vector geospatial data formats. Furthermore, a new Tcl extension will allow for reading and redenring of these formats in a Tk canvas (Tkpath) widget. The exact supported GIS file formats can be found at: http://www.gdal.org/formats_list.html http://www.gdal.org/ogr/ogr_formats.html
