Syntax to retrieve x/y coordinates in python?

ThomasMeyer — Wed, 22 Sep 2010 19:49:07 GMT

I'm opening a point shapefile cursor, while row: ...

shouldn't it be something like:

row.shape.x ??

I've tried for many hours looking for this answer online to no avail. Is there no api? I don't see Shape 'class' on the "Geoprocess Object Model", what am I missing?

Thanks a bunch! that got me on the right track. Although, sadly, I thought I'd be getting back a lat/long values as the x/y.

I'm starting with a shapefile of nad/stateplane, project it to geographic, and want to then extract all the lat/long values (all within the script). *sigh* back to google...

edit: nevermind, it works, I forgot to uncomment the projection command, lol. here is some code:

rows = gp.UpdateCursor(proj_shp)
row = rows.Next()
while row:
feat = row.shape
pnt = feat.GetPart(0)
print "x: " + str( pnt.x )

If they are points, just calculate xy values by calling the ArcToolbox tool, and populate the attribute table with lat/long. Then use a search cursor to extract the lat long for each point.

Sorry, what I meant to say was reproject the data into WGS84 and use the AddXY Coordinates tool to populate the attribute table with lats/longs, then use the cursor to step through the records.
