Re: GML to svg

2004-05-21 14:24:14


for the sake of comprehension, what svg 
fragment should this gml fragment output:


    <gml:Box 
srsName="http://www.opengis.net/gml/srs/epsg.
xml#4326">
      <gml:coordinates>0.0 0.0,100.0 
100.0</gml:coordinates>
    </gml:Box>

whatever svg path you require, can you 
describe the correlation between that path 
and these gml:coordinates?

Hello,
I have a valid GML file descriped follow, 
it was validated by xmlspy. I want to 
transform
it to SVG format using xslt but I m newbie 
in xsl language.
follow the xsl file that I writed but it 
cant give me a the same result described in 
the
output svg file.
from this can any one see this files to 
help me to write the xslt file correspind to 
my
gml file to give me the same result of the 
svg file described in follow. 
thanks advanced.
