    v25 v26  
    22[wiki:"CookBook Eda"] 
    33= First an example for Britany = 
     4We chose to work on a reduced scale to build the queries as the clc is just damn too big for us, and raster approches are not yet avalaible in postgis, though we fancy using the functions displayed in the developpement page http://trac.osgeo.org/postgis/wiki/WKTRaster. 
    45== building a table of clc only for Britany == 
    56After several trial neither --- ST_Crosses --- nor  --- ST_Contains --- did work, the example with ST_Intersects provides a surface that is larger than britany, but ST_Crosses missed the area near the coasts as the geom had to be fully within Britany.
