[FWTools] Fwd: Get projection from shp using GDAL and Python

[David Fawcett]

Susana,

I just ran this code on my local machine and it works.  It prints the
text representation of the SRS.  (I am actually running these Python
modules from OSGEO4W, but it shouldn't really matter.)

from osgeo import ogr,osr

shpPath = "c:/workshop/examples/data/mn_counties.shp"
shapeData = ogr.Open(shpPath)
layer = shapeData.GetLayer()

srsObj = layer.GetSpatialRef()

srsText = srsObj.ExportToWkt()

print srsText
