<div dir="ltr"><div>hello, everyone!</div>
<div> I got the table of the map from the shp file. but the data of coordinate looks like in the form of very big double datas. such as x="-4106.111" y="-1492.8695",</div>
<div> I got those data in this way:<strong>select name,assvg(the_geom,0,4) from PT_bgyl_point</strong> </div>
<div> but the coordinate system of the svg is the same as the shape file table. as the coordinate system is not suitable to be used on the mobile phone to display.</div>
<div> and how can I do to formate the data, so that I can make the data in my own coordinate system and got the (0,0). then display the svg in the mobile device.</div>
<div> can anyone give some advice?</div>
<div>btw:Icarry out this using java and postgresql 8.3.</div>
<div> thankyou very much.</div>
