[Gdal-dev] Simple SHP file creation with Python..API question

[Aykut KOÇAK]

Thanks those were very helpfull,

I have already written below code to update single point within a point 
type shape file, but it can not update the file.

I am not well experienced on OGR API yet!.

anybody comments on it ?

import ogr,getopt,sys

shpfile='point.shp'
location='32.862450,39.966323'
(options, arguments) = getopt.getopt(sys.argv[1:], 
"l:f:h",["location=","file=","help"])
for (switch, val) in options:
if switch in ('-h', '--help'):
sys.stderr.write("usage: updateshp [-h] [-l] [--location] [-f] [--file]\n")
raise SystemExit,0
elif switch in ('-l','--location'):
location = val
elif switch in ('-f','--file'):
shpfile = val

def main():
global shpfile
global location
map=ogr.Open(shpfile,1)
layer=map.GetLayer(0)
ftr=layer.GetFeature(0)
geo_ref=ftr.GetGeometryRef()
geo=geo_ref.GetGeometryRef(0)
loc=location.split(',')
geo.SetPoint(0,float(loc[0]),float(loc[1]),0)
map.Release()
return
main()
