Hi,there<br> I tried to load all road polylines in box 104,30,106,32(EPSG:4326) with sql:<br>SELECT AsSVG(intersection(the_geom,GeometryFromText('POLYGON((104 30,106 30,106 32,104 32,104 30))',4326)),1,1) AS svg_geom FROM road_polyline WHERE the_geom && setSRID('BOX3D(104 30, 106 32)'::box3d,4326)<br><br>I got some results like,<br>"M 104.1 -30.8 l 0 -0 0 -0 0 -0 -0 -0 -0 -0 -0 -0 0 -0 "<br>"M 104.2 -30.8 l 0 0 0 0 0 0 "<br>"M 104.2 -30.8 l 0 0 "<br>"M 104.2 -30.8 l 0 0 0 0 "<br>"M 104.1 -30.8 l 0 -0 0 -0 "<br>"M 104.1 -30.8 l 0 0 0 0 "<br>"M 104.2 -30.8 l 0 0 0 0 0 0 0 0 0 0 0 0 0 -0 0 0 0 0 "<br>"M 104.1 -30.8 l 0 -0 "<br><br>what does this mean? It should be something like,<br>M 104.1 -30.8 l 104.* -30.* l p3x p3y l p4x p4y<br>Why does there so many zero(0)?<br><br>I cannot make it display on my SVG document.<br><br>thanks in advance.<br>alex<br>
