    4242== Storage ==
    43 For portability, the default storage for Features is the normal database via Web2Py's [http://mdp.cti.depaul.edu/examples/default/orm DAL].
    44 
    45 In order to support Lines & Polygons we need to store as [http://en.wikipedia.org/wiki/Well-known_text WKT]
    46  * UI for Points can hide this behind simple Lat/Lon
    47  * Q: Which lib best for this?
    48   * !WorldMill: http://trac.gispython.org/lab/wiki/WorldMill
    49    * wraps OGR: http://www.gdal.org/ogr/osr_tutorial.html
    50   * Shapely: http://pypi.python.org/pypi/Shapely/
    51    * wraps Geos: http://trac.osgeo.org/geos/
    52 
    53 An option should be provided to store in [http://postgis.refractions.net PostGIS] instead, where available, as then can have spatial indexes for speed.[[BR]]
    54 Q: Could we extend DAL for spatial indexes?
    55  * [http://groups.google.com/group/web2py/browse_thread/thread/7551b50ef3ca72a8 DAL can be bypassed] to allow other ORMs to be used: {{{response.custom_commit=lambda: do_commit()}}}
    56 
    57 Q: integrate [http://featureserver.org FeatureServer]?
