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