With mapserver map file and postgis, I need to construct st_slope postgis raster and then display it with mapserver dynamically
that is to say how can I operate following postgis expression in mapserver map file? WITH r AS ( -- union of filtered tiles SELECT 206 ST_Transform(ST_Union(srtm.rast), 3310) AS rast FROM srtm JOIN sfpoly sf stom extent SELECT ST_AsRaster(ST_Transform(sf.geom, 3310), r.rast) AS rast FROM sfpoly sf CROSS JOIN r )SELECT ST_Clip(ST_Slope(r.rast, 1, cx.rast), S T_Transform(sf.geom, 3310)) AS rast FROM r CROSS JOIN cx CROSS JOIN sfpoly sf; regards -- Ahmet Temiz Jeoloji Müh.
